Description

The present invention relates to a knowledge management device that manages manufacturing knowledge using the 3D CAD model, a terminal of the knowledge management device, and a program for the knowledge management device.

  In recent years, in the manufacturing industry that manufactures heavy industry, plants, shipbuilding, vehicles, electricity, electronic products, etc., there are global competitions such as quality assurance, low cost, and development and production lead time reduction. In global product development, production, and service operations, further quality assurance and efficiency are required among companies, companies, and companies.

In recent years, demands for products differ for each region in the world for companies, and the types of products are increasing. In addition, the procurement of parts and materials for products has been localized, and the work of product development, production, and service operations has become complicated and specialized.

In order to carry out such operations rationally, companies have global bases and operate according to local needs and the environment. However, the people who make up a company's organization are people, and human resource development is indispensable for the growth of a company. To this end, it is necessary to continuously carry out global and complex operations while changing the human resources that have been nurtured at the bases and organizations and developing them more extensively.

Methods for controlling things such as parts procurement arrangements, logistics control, and product sales and distribution have progressed along with technological advances in information systems, and global location information has also been acquired and management without waste has been implemented. However, work methods for performing business such as product development, production, and service are not so advanced.

In recent years, in order to solve these problems, for example, CAD, PLM (Product Lifecycle Management), etc. are being used for product design. However, CAD does not come to support design thinking and is often used as a modeling tool with an emphasis on shape creation. CAD annotations (notes, etc.) serve as functions for supplementary description of drawings such as dimensions. The relationship between the product design intention, purpose, and means cannot be read from CAD. In addition, the communication of design intentions between set manufacturers and component suppliers is inefficient for global design and production because there are many paper drawings and specifications. The same applies to facility design work.

The PLM also has an attribute for each part number, and cannot handle manufacturing unit data such as quality accuracy for a part of the part shape and manufacturing cost for a part of the part shape.

Although software called a knowledge system is also available on the market, the management unit of this software is the document unit (document unit). The title name, date of creation, department name, creator name of the document. By inputting a plurality of keywords called tags, necessary documents are retrieved and displayed to the user. However, since it is a document unit, there is a problem that necessary knowledge such as knowledge relations cannot be quickly obtained. Moreover, it cannot be classified into knowledge units, and systematic understanding is difficult. In order to know the purpose and means, the reason for choosing the means, etc., you have to read many documents. There is also a problem that I do not know if there is enough description there. The PLM has the same function and is not sufficient.

Design review checklists for 3D CAD models for new product development and model change products are created by hand-printing past trouble collections, designs, production requirements documents, etc., which takes time and is not accurate enough The maintenance of the checklist is not performed continuously. For this reason, technical judgments vary depending on the person, such as pointing out problems in design reviews at the product development stage, and there are many reworks in product design.

Technical comparisons of products are conducted as needed by examining documents such as past drawings and reports, but the person in charge may change due to personnel changes. Because they are not uniform and fragmented, it is easy to make a difference in technology comparison and judgment. Also, not all of the advanced technologies are known.

There is also a system for recording actual processing scenes as videos as a knowledge storage system, but even if you can understand visually, the reason why you adopted that method needs to be supplemented by voice or text There is a problem that editing is not easy due to the time-consuming method. Further, since this method does not target knowledge in designing such as a design intention of a product designer, the knowledge that can be accumulated is limited.

Knowledge is based on the past knowledge of many designers and experienced workers at the product development stage, or the knowledge is gathered systematically while acquiring new knowledge to increase the amount of knowledge, and the design drawing is created with that knowledge Has been. In this natural organizational activity, there is a need for a method that can accumulate and manage knowledge, and methods such as going back to memory after design completion and organizing knowledge can lead to memory-dependent leaks and the dissolution of product development teams. There is a problem that it is not fixed because the method is out of timing.

As described above, it cannot be said that the accumulation of knowledge has been sufficiently realized as a countermeasure against moving with people due to the transfer of human resources and the mobility of human resources between companies. For this reason, it is also true that quality problems such as misjudgment by people are occurring globally. There are also cases where the company is struggling to compete in the market due to price differences with similar products from other companies.
Companies are responsible only for their specialized departments. However, in order to carry out product development, production and service, it is necessary to carry out business with an awareness of the balance between appropriate quality, function and production cost. To solve such problems, it is important for companies to accumulate and manage knowledge that all employees should have in common sense.

For example, a system described in Patent Documents 1, 2, and 3 has been proposed as a system for managing knowledge in design and production operations.

In particular, this input data is converted into integrated data described in a tagged language that can be expressed in a hierarchical structure, and stored and managed. However, this Patent Document 1 does not consider the knowledge storage format.

First, when a processing instruction for 3D CAD model acquisition management is transmitted from the terminal 100 to a specified product name, the 3D CAD model acquisition management means 71 transmits the instruction to the management server via the network 500. 2 receives and sends the command to the 3D CAD model capture server 1. In this server, all the 3D CAD models of the designated product name are converted by the program that performs format conversion processing to Viewer data, and all the converted 3D CAD models of the designated product name are transmitted to the knowledge storage server 5. The knowledge storage server 5 stores the converted 3D CAD model in the 3D CAD model storage unit 51 together with the product name by operating the program of the knowledge storage server 5.

The technical classification management means 72 is for handling technical terms in the company in a unified manner by the knowledge management apparatus 1000. For example, as shown in FIG. 9, the structure of the storage table is divided into a function classification name and a detail classification name for a product divided into a large classification, a middle classification, and a small classification, and a plurality of classifications are provided for the small classification. A function name, which is a word that describes the performance of the function, is registered as a master, and a word code is assigned to the word of the function name by processing the program in the knowledge storage server 5 and stored in the word storage unit 52.

An example of an input method to the table in the word storage unit 52 is shown in FIG. The screen of FIG. 10 is displayed on the terminal 100 by operating the terminal 100 in which the program of the knowledge management apparatus 1000 is installed. For example, when a classification name is input, the terminal 100 transmits the information to the management server 2. The management server 2 recognizes that the information is information for the knowledge storage server 5 and transmits it to the knowledge storage server 5. When the knowledge storage server 5 receives the data, the knowledge storage server 5 determines the classification table of the word storage unit 52 and compares it with the data in the table. If there is no same data, the knowledge storage server 5 additionally stores it in the target data field. For example, a classification name “function” is registered as a table name, and braking and acceleration are stored as an example in which an automobile is a product as a word expressing the function. At this time, a unique word code is assigned to each word of braking and acceleration and stored. If there is already the same data, a message that it is duplicated is transmitted to the management server 2, the terminal 100 receives the message via the management server 2, and cancels processing cancellation information according to the input to the terminal 100. Then, the operation of the management server 2 and the processing of the knowledge storage server 5 are finished.

Thus, the registration of the data of the words belonging to each category stored in the word storage unit 52 of the knowledge storage server 5 is registered from the terminal 100. By this registration, the word storage unit 52 registers the data of this word in the classification name. For example, in the above description, the classification name of function is registered as a table name, and when braking and acceleration are stored as words expressing the function, the component name belonging to braking, which is the function name, is registered here. For example, register words such as brake pedals.
In response to an instruction from the terminal 100, the input data is transmitted. Similarly, the word storage unit 52 additionally stores the word “brake pedal” in the storage table of the brake component names. A unique word code is given to the word “brake pedal”, which is the input component name, by the program processing of the knowledge server 5 and stored. The overlapping process is the same as described above, and the operation will be omitted later.

This word code is used for correspondence with foreign language words representing the same word code when converting knowledge data to foreign languages. That is, it has a table that holds words representing the same meaning of a plurality of foreign languages for the word code. As a result, the knowledge data stored in the knowledge management apparatus 1000 can be accumulated using words having a globally common meaning.

Similarly, FIG. 11 shows a structure of data in which processing techniques are divided into a large classification, a medium classification, and a small classification, and a plurality of processing names are registered for the small classification, and word codes are assigned and stored. .

Thus, the language classification system used for the expression of knowledge is shown in FIG. 12, for example. As the language classification system, the words used by each business function are classified into technical words and management words for each business function such as design and production. Product functions and quality realization, design words expressing design intent, production management words used in production, quality control words, product failure expressions used in service operations after sales, repair expressions, etc. Is input and registered in the word storage unit 52 of the knowledge storage server 5 by a technology classification management program. For example, when a functional expression table is registered as an example of a technical language table used by the designer in the knowledge management apparatus 1000, the table is registered as a functional expression 004 table corresponding to the design 01 and the technical language A. This table has a data structure for registering functional expression words. Accordingly, the ID of the table in this case is determined as a table ID for storing functional expressions which are technical words used in the design by 01A004 by combining the symbols in order.

The display screens on the terminal 100 and the terminal 200 of the knowledge management apparatus 1000 display a choice using design words when a design is selected as a business function specified by the user. When production is selected, production words are displayed. That is, in the program of the knowledge management apparatus 1000, words to be assigned in the screen display are searched from the table of the word storage unit 52, and the words are displayed and are not embedded in the program. The words displayed at the time of the user's selection operation by the terminals 100 and 200 are also words searched from the table of the word storage unit 52. When using a word that is not a candidate for selection, registration processing is temporarily performed in the temporary word storage unit 52, and formal registration processing in the word storage unit 52 is performed based on human judgment. For this purpose, the registered language has formal and temporary registration classification flags.

Adjectives such as large and light and evaluation symbols such as ○ and △ are also registered as words.

The knowledge storage server 5 has a function of registering a knowledge input form described later. In the terminal 100, the knowledge input form is selected by the user's operation by selecting the classification and words stored in the word storage unit 52 by the technical classification management means 72 and the input form title and the selection candidate of the input unit. The knowledge input form thus created is displayed and created, and is transmitted to the management server 2 by an operation from the terminal 100. The management server 2 stores it in the word storage unit 52 together with the name of the knowledge input form. For example, a knowledge input form 557 shown in FIG. 15 described later is an example. The data input to the knowledge input form 557 at the terminal 200 is stored in the knowledge storage unit 53 of the knowledge storage server 5 , and the knowledge input form 557 is transferred to the terminal 200 by a call command from the terminal 200. Is displayed.

The knowledge management apparatus 1000 also combines the words registered in the word storage unit 52 to express the name of the part. The 3D CAD model stored in the 3D CAD model import storage unit 50 is provided with management information such as a product number, a product name, and a component table configuration code that are assigned to identify one 3CAD model in the CAD or PLM of the design. ing. In particular, in the development stage, the product number, product name, and component table configuration code are often changed and are not suitable for accumulating general knowledge. Instead, a unified part name used in the knowledge management apparatus 1000 (hereinafter referred to as a unified part name, and also referred to as a unified part name code in the description of the system processing ) is registered.

How to make a unified part name is, for example, the position classification names such as the front and rear parts that divide the position of the smallest unit part in the product and the detail position classification names such as the right and left of the front part representing the detailed position, A function classification name that represents a function in a product and its detailed classification name are used, and a single part is replaced by a combination of a specification expression word, a customer name, a destination name, etc. that expresses part variations. Define a unified part name that can be specified. This definition is created by the terminal 100 by combining words in the word storage unit 52. For example, one part name is created and registered by an expression such as a steering wheel of a G-grade right-hand drive car for domestic use. By this method, it is possible to accumulate knowledge about the term steering handle, knowledge about a narrow range of term steering handle for domestic use, and hierarchical knowledge about the steering handle for G-grade right-hand drive cars for domestic use. . This hierarchical knowledge accumulation is difficult only by product number and product name.

In this way, the technology classification management means 72 of FIG. 8 not only defines the technology classification and the words, but also each of the 3D CAD models that are Viewer data registered in the 3D CAD model storage unit 51 of the knowledge storage server 5 for the first time. The process of assigning a unified part name is performed in accordance with a user operation of the terminal 100.

This operation is performed by using the menu screen shown in FIG. 30 displayed on the terminal 100 to display the product number, product name, and parts table initially assigned to the 3D CAD model in response to an operation instruction by the user pressing the button of the 3D CAD model import management unit. Management information such as a configuration code is displayed on the screen, and by the selection operation of one 3D CAD model by the management information displayed by the user at the terminal 100, the search instruction information is transmitted from the terminal 100 via the network 500 to the management server. 2 is transmitted. The management server 2 transmits the received search instruction information to the knowledge storage server 5. In the knowledge storage server 5, processing for searching the received search condition is performed by the program, and the corresponding 3D CAD model is specified. The 3D CAD model is displayed on the terminal 100 via the management server 2. The displayed 3D CAD model is checked by a person together with management information such as the product number, product name, and component table configuration code originally assigned to the 3CAD model, and the word registered and stored in the word storage unit 52 in advance is selected. Combined to determine the unified part name. By this operation, the unified part name in the knowledge management apparatus 1000 is newly assigned to the 3D CAD model, and the unified part name is stored in the knowledge storage server 5 together with the 3D CAD model. The management information such as the product number, product name, and parts table configuration code originally assigned to the 3CAD model is also stored in the knowledge storage server 5 together with the unified part name for use when the design change data is imported next time. To do.

FIG. 13 shows an example of the data structure in the knowledge storage server 5 of the knowledge management apparatus 1000. Here, the 3D shape information represents information about the shape, has a unified part name code, and the external management information has management information such as a registered product number, a product name, and a component table configuration code by an external CAD or the like. Part. The knowledge model has a unified part name (code) as knowledge management information in order to specify the data of the 3D CAD model. In the knowledge management apparatus 1000, the 3D CAD model is specified by the unified part name code instead of the management information given externally. Further, feature point information to be described later is stored together with the 3D shape as 3D shape information. Here, 3D shape information and feature point information are divided separately. This corresponds to the change of the 3D shape, and is separated from the feature point information.

FIG. 14 shows an example of a method for associating knowledge in the knowledge management apparatus 1000 with a 3D shape. This is a basic user interface of a knowledge registration screen displayed on the terminal 200. On this screen, an operation in which the user determines the position of knowledge at the feature point 552 of the 3D shape of the terminal 200 is drawn as an arrow 553. To do. In this case, the user represents an operation of registering knowledge in a portion indicating a hole in the 3D shape. This drawing is a three-dimensional drawing. When the arrow is drawn, a circle mark is created and displayed on the arrow head 556 by the program of the terminal 200 in order to facilitate the operation of the pointing device such as the user's mouse. At this time, saved information such as the coordinates (x, y, z) of the feature point 552 and the line type, shape, and end point coordinates of the feature point drawn by the operation by pressing the save button from the terminal 200 are displayed. It is transmitted to the management server 2. The method for drawing the feature points may be any method that can be visually understood by the user other than the arrows.

When the management server 2 receives the storage information, the management server 2 transmits the storage information to the knowledge storage server 5. The knowledge storage server 5 recognizes the unified part name code from the received stored information and operates a process for determining a management number (hereinafter referred to as a feature point management number) for managing a new feature point to be given to the unified part name code. Then, the determined feature point management number is transmitted to the management server 2, and the management server 2 transmits this feature point management number to the terminal 200.

The terminal 200 displays the received feature point management number on the display unit 565 of the head 556 of the arrow 553 of the 3D CAD model displayed on the terminal 200 by the program of the terminal 200. A confirmation message prompting the user to confirm registration is displayed, and the feature point 552 is stored in the knowledge storage database server 4 of the knowledge storage server 5 together with the unified part name code by pressing the confirmation OK button on the terminal 200 by the user. The

The knowledge storage server 5, arrow 55 3 and information such as the coordinates and line type head 556 is added with the feature point management number to the 3D shape, 3DCAD model storage unit of 3DCAD model storing server 3 a unified component name code as the file name 51. The knowledge storage unit 53 stores the feature point management number using the unified part name code as a key.

Thus, 3DCAD model holds feature point management number, information such as coordinates and line type of the arrow 55 3 and head 556 are stored, the feature point into a unified part name code for specifying a 3DCAD model for knowledge management information I have a management number. The knowledge storage server 5 can store knowledge in the stored feature point management number and the management number.

If the user designates a unified part name by operating the terminal 200, the designation information is transmitted to the management server 2, and the terminal 200 acquires the 3D CAD model acquired from the knowledge storage server 5 and the arrow 55 held in the model. 3 , the head 556, and the feature point management number are displayed, and further, by specifying the feature point management number of the terminal 200, the operation of acquiring knowledge management information information from the knowledge storage server 5 is performed.

Subsequently, when information for acquiring only the 3D shape of another 3D CAD model is transmitted to the management server by the operation of the terminal 200, the management server 2 receives the corresponding 3D from the 3D CAD model storage unit 51 of the knowledge storage server 5. The shape is received and transmitted to the terminal 200. The terminal 200 displays guidance on the screen for replacing the received 3D shape with the currently displayed 3D shape. The displayed 3D shape is replaced with another received 3D shape and displayed by the user's replacement request operation.

In this case, ahead and the displayed have held to have feature point management number to the 3D shape and the arrow 55 3 head 556 is displayed in the original coordinates. The stored knowledge and 3D CAD model can be selected and displayed in a 3D shape according to the request of the user of the terminal 200 by the knowledge storage structure of FIG.
Any combination display of knowledge and 3D shape is possible on the simultaneous display screen of knowledge and 3D shape, and knowledge reference and diversion processing are possible.

Copy the feature points and knowledge described in the 3D shape of the reference product to the 3D shape of the new product development or model change product as the knowledge of the new product development or model change product. A feature point assigned to the 3D shape of the referenced product, a unique management number of knowledge, and a diversion section for storing the diversion are added and stored as knowledge about the 3D shape under development.

For the unified part name code, the feature point management number is stored in the table of the knowledge storage database server 4 of the knowledge storage server 5 such as the feature point management number, the feature point classification, the processing classification, and the knowledge management number.

Furthermore, a plurality of feature points are grouped, and the new upper feature point is separated from the feature point management number for the unified part name code, and the upper feature point management number and the lower feature are added to the feature point management number. The point management number is stored.

For example, requirements and conditions necessary for designing a certain function are knowledge registered in a higher-level feature point management number. Furthermore, when the 3D shape is specifically expressed as a structure that satisfies the requirements and conditions, the feature point of the 3D shape is related to the lower feature point management number below the higher feature point management number. Become.
The method of inputting this procedure in reverse is the processing method of the knowledge management apparatus 1000.

Generally, there are a number of possible design stories for realizing functions and quality, and an idea evaluation table, for example, QFD (Quality Function Deployment quality function deployment) is created using specific implementation means as a matrix. . One idea is adopted from this idea evaluation result, and the idea is embodied. In the case of an automobile, words expressing the classification registered in the secondary and subsequent feature point management numbers are a braking function, an acceleration function, and the like. There can be multiple ideas that can be considered for achieving this performance value for this function. Each of the plurality of ideas is broken down, and the final conclusion is a shape as a 3D CAD model, which is its material.

The feature point of the knowledge management apparatus 1000 uses a 3D CAD model in order to realize specific communication with a person. For example, in product development, a model in the middle of design and a 3D CAD model of a similar product in the past are objects of feature point description. In facility design, a model in the middle of design or a 3D CAD model of past facility design is a description target of feature points.

The 3D CAD model and knowledge of past similar products are displayed by operating the terminal 200. The displayed knowledge can be obtained by the user together with the arrow with the primary feature point management number. It is easy to organize thoughts from primary feature points to N-th feature points. When the details are broken down from the higher-level objective of designing an automobile, a specific 3D CAD model of the design is finally reached, but this requires the development of a vast amount of description. Also, it is not useful to describe it. Rather, it is an efficient accumulation of knowledge to describe higher-level feature points within a meaningful and necessary range starting from specific feature points. For this purpose, the development of feature points from the first order to the Nth order is adopted.

The knowledge described in the upper feature points can be used as knowledge used in QFD (Quality Function Deployment quality function deployment). The QFD matrix may also be stored in the knowledge storage device.

FIG. 15 shows an example of a screen for describing knowledge. Reference numeral 550 denotes an area for describing a feature point with respect to the 3D shape, and reference numeral 551 denotes an area for each organization to describe knowledge about the feature point. For example, the registration of the design intent in the 3D shape indicates the portion to be described by a method such as describing 553 arrows for the 3D CAD model in the 550 region. The tip 552 indicates the feature point itself.

Since the objects of knowledge range from materials, functions, parts, parts of parts, etc., arrows are used as one of the methods for visually describing the position to register knowledge in the 3D CAD model. For example, when an arrow is used, when the arrow 553 indicates a part of the 3D CAD model, the arrow D is always drawn so that the tip of the arrow touches the surface of the 3D CAD model. When indicating a space such as a hole, a method of connecting the tip to a dimension line indicating the size is adopted. If necessary, a cross-sectional view of the 3D CAD model may be created and described in the cross-sectional view. Therefore, the knowledge accumulation method based on the 3D CAD model includes a knowledge accumulation method for two-dimensional digital data. On the other hand, when a material or the like for the entire 3D CAD model is shown, the feature point 552 is always a coordinate inside the model of the 3D CAD model, and the tip of the arrow 553 is an object of knowledge by drawing the end of the line to the inside of the 3D CAD model. Is used to distinguish a part of the 3D CAD model from the whole.

The description of the feature point is selected from the feature point category 554. The word displayed on the target of the feature point is the result of searching the word storage unit 52 for the word stored in 01A008, which is a table of the shape expression 008 in the design word 01 in FIG. Is displayed as a selection candidate of the screen 554. For example, when a hole is selected by the user's operation from the display and the lower save button 559 is pressed, the input data is transmitted to the management server 2 and transmitted to the knowledge storage server 5. The knowledge storage server 5 stores the feature point management number in a table storing the feature point by the program.

In FIG. 15, by specifying the head 556 of the arrow with a pointing device such as a mouse, the pop-up screen 551 stored in the knowledge storage server 5 is transmitted via the management server 2 and received by the terminal 200, A pop-up screen 551 is first displayed on the device 200.

In the upper part 555 of the pop-up screen 551, business functions such as design, production technology, production, inspection and service previously registered and stored in the word storage unit 52 are displayed. A knowledge input form 557 for inputting knowledge dedicated to business functions such as design intention, processing method and management method is transmitted from the knowledge storage server 5 and displayed on the terminal 200.

To register the design intent, a design input knowledge input form 557 is displayed by pressing a design button.

To register the specific contents of the design intention, the characteristic point characteristics, purpose, quality characteristics, and quality standard value tolerance are input to the knowledge input form 557 shown in FIG. A round hole is selected for the characteristic of the feature point, and a high-order target word is selected for the purpose, and knowledge that the hole of the feature point 552 is an assembly standard is selected and input. Knowledge that requires the dimensional accuracy of the hole at the feature point 552 is input to the quality characteristic. For these inputs, data is acquired from the language storage unit 52, a program for displaying selection type inputs to the user operates, and the selected result is stored in the knowledge storage unit 53 using the feature point management number as a key.

In order to describe the knowledge of production technology for the same feature point, as shown in FIG. 16, the uppermost section name of the pop-up screen 551 displayed by designating the same arrow head 556 as the above design intention. Select production technology from As a result, a knowledge input form 557 for the displayed production technology is displayed. This knowledge input form 557 is displayed by selecting the display item from the language classification of production registered and stored in FIG. 12 and the technical classification management means 72 and registering and storing it in the knowledge storage server 5 as a knowledge input form. .

For example, in selecting the processing method for the round hole, which is the feature point 552 in FIG. 16, a drilling device capable of ensuring the accuracy is selected from the tolerance displayed on the design knowledge input form 557 in FIG. The name of this drilling device can be selected by the technical classification management means 72 when it is registered in advance as the name of the drilling device in the classification as the drilling method. Alternatively, if not registered in advance, the drilling device name is provisionally registered. The formal registration procedure is the same as described above, and will be omitted.

For example, the name of the drilling machine used for processing the round hole which is the feature point 552 in FIG. 16 is selected and input. At this time, by pressing the work procedure display button 560 from the name of the drilling machine, the work procedure of the corresponding drilling machine registered and stored in the knowledge storage unit 53 in advance is displayed. The displayed contents are taken from the pallet. Position and set the material in the drilling machine. Set position is visually check whether correct. Press both hands start button of drilling machine. Remove the processing panel. Load the processed parts on the pallet. Here, if the work procedure is not registered in advance, it can be input and temporarily registered. Since this method of formal registration is the same as described above, it is omitted.

As a result, by specifying the head 556 of the arrow drawn from the feature point 552, the user can confirm the relationship between the design intent and the processing method of the production technique with the terminal 200. By such means, the knowledge of engineers in charge of many different specialized fields can be related by sharing the feature point management numbers in the common 3D CAD model.

As described above, a plurality of knowledge descriptions can be performed for one feature point. As shown in FIG. 14, when the feature point management number 565 is given to the head 556 of the arrow 553 indicating the feature point 552, the knowledge described in this feature point management number is Each time the head 556 of the arrow 553 is designated, a new knowledge management number is automatically given by the program of the knowledge storage server 5 . The data entered in the knowledge input form 557 of FIG. 15 with the design designated and displayed with the head 556 is registered as data of the knowledge management number 566. Similarly, the pop-up in FIG. 16 of the production technique designated with the head 556 displayed. Data input on the screen 557 is registered in the knowledge storage server 5 as data of the knowledge management number 567.

As for the display order of knowledge management numbers below the feature point shown in FIG. 14, the knowledge management number 566 that is displayed first displays knowledge that explains the purpose of this feature point. This knowledge is recognized by pressing the design button on the display unit 555 in FIG. Thereafter, the knowledge management number is assigned to the added knowledge below in the order of addition.

The knowledge management number is displayed hierarchically below the feature point management number. As an explicit expression for making it easy to understand grouping, design, production technology, production, inspection, service, and the like of feature points, which will be described later, classification may be performed by adding colors and symbols.

Further, it is possible to perform a narrowing search by designating the display from the user by design, production technology, production, inspection, service, etc., avoiding the complexity of the display, or select display from the classification registered in the word storage unit 52 or within the classification It is also possible to display by narrowing down by selecting a specific word.

The contents of the work procedure displayed at 559 in FIG. 16 are divided into words and phrases such as what, where and how, as shown in FIG. 17, and registered and stored in the knowledge storage unit 53 by the technical classification management means 72. Is displayed. The manufacturing cost is calculated and displayed in 559 of FIG. 16 from this data, for example, the cost table for obtaining the manufacturing cost outside the knowledge management apparatus 1000 and the work time for each work content of FIG.

Further, when 561 in FIG. 16 is designated, an idea evaluation table 562 is displayed. One evaluation matrix is displayed by selecting a plurality of processing methods registered in the technical classification management means 72 and selecting the evaluation items such as quality, manufacturing cost, and cost amortization. When selecting the processing method for this feature point, the evaluation result is displayed in each column of this display matrix by reference from an external database of quality, process capability, manufacturing cost, production capability, etc., or by manual input. Save your thoughts and evaluation results. As a result, the person involved in manufacturing can know why the press work is selected as the hole machining method. Not only knowing the results, but also knowing which processing methods are considered as candidates for processing, what is evaluated as an evaluation item for each candidate, the reason for the judgment, etc., and quantitative values at that time be able to. Once this knowledge is once stored in the knowledge storage server 5, from the next time, the same or similar material, plate pressure, hole diameter, tolerance of diameter, and processing knowledge of the number of production plans can be retrieved and displayed. The processing method can be determined quickly with reference to the evaluation matrix as the display result.

Similarly, in order to register the knowledge of the inspection engineer for the feature point 552, the inspection is selected from the uppermost category name of the pop-up screen 551 displayed by designating the head 556 of the same arrow. As a result, the knowledge input form for the displayed examination is displayed. This knowledge registration form is displayed by registering and storing the display item as a knowledge registration form from the language classification of the examination registered and stored by the technical classification management means 72. For example, the work procedure of the measuring machine used to measure the processing accuracy of the round hole, which is the feature point 552 in FIG. 16, is input. At this time, by pressing the display button of the measurement work procedure from the name of the measurement machine, the work procedure of the measurement machine stored in advance in the knowledge storage unit 53 is displayed. Hereinafter, since the time calculation and the inspection cost calculation of the measurement work are based on the same method, the description is omitted.

As described above, the knowledge shared by the feature points 552 finally accumulates information in association with the manufacturing cost of hole machining and the accuracy measurement result of the hole. A series of knowledge from the related design intent to inspection is stored in the knowledge storage server 5 of the knowledge management apparatus 1000 as one piece of related knowledge in units of feature points. When this series of knowledge is knowledge of general relations, it is stored as data having a knowledge standard flag in the knowledge standard storage unit 55 of FIG. This knowledge standard storage unit 55 has the product name, function name, unified part name, feature point classification, feature point management number, characteristics, purpose, quality characteristics, tolerance, number of quality problems, and knowledge standard flags registered as standard knowledge. Stored as a structure. In FIG. 32 later, when the check list of the product design review is created, it is displayed by searching the data in the knowledge standard storage unit 55.

Using the data of the knowledge standard storage 55, the design, production technology, and inspection inputs can reduce the registration of knowledge when selecting standard knowledge. Also, each person in charge can know the relationship of knowledge other than the person in charge by the feature point management number. In many manufacturing companies, the words used in business for each specialized field are unique, and the relationship between unique words is connected by tacit knowledge. As described above, according to the inventor, as a method of connecting this tacit knowledge, a 3D CAD model is used, and a feature point as a point of interest in the 3D CAD model is described with respect to a specific part or the whole of the 3D CAD model. As shown, the head 556 of the arrow is designated to associate the tacit knowledge with each other.

A knowledge description of product service work in the market is also input from the screen of FIG. For example, a feature point is input to the 3D CAD model for a part of a product in which a failure has occurred or a phenomenon of operation failure. By this method, the transmission of defect contents to related companies becomes more accurate than by documents. In the case of inputting a defect related to the accuracy of the hole in the case, the defect phenomenon is input by designating the head 556 of the same arrow. The defect phenomenon can be selected from the product function stored in the word storage unit 52 and its subcategory, and the unified defect phenomenon classified into the product function words can be input.

Descriptions of service failures are often written in free text, and it takes time to interpret them, which can delay the identification of the cause of the failure. From the terminal 200 of the knowledge management apparatus 1000, the 3D CAD model is displayed by selecting the product name, function classification name, and detailed function name from the menu screen shown in FIG. 30, and only the 3D CAD model relating to the detailed function name is displayed. . In the screen, a pop-up screen displayed by finding a part having the corresponding round hole from the 3D CAD model of the estimated part, displaying the feature point of the round hole, and specifying the head 556 of the arrow of the feature point The service is selected from the division name in the top 555 of the menu. As a result, a knowledge input form for the displayed service is displayed. This knowledge input form is displayed by registering and storing the display item as a form from the service language classification registered and stored by the technical classification management means 72. For example, a failure phenomenon, date of occurrence, use date, failure estimation factor, failure treatment, and the like are displayed. In this way, service defects are also stored in the knowledge storage server 5.

Thereby, the person concerned with the manufacturing company such as product design and production can confirm the malfunction phenomenon with the terminal 200 via the network. FIG. 18 shows an example of the screen. The person involved in the manufacturing company uses the terminal 200 to control access based on the registered authority of user access in units of permitted products, parts, etc., with a personal user ID and password, as shown in FIG. Thus, the search information is transmitted to the knowledge storage server 5 for the permitted information, and the terminal 200 receives and displays the information acquired by the management server 2. When permitted by access authentication of the access control server 6, the failure information stored in the knowledge storage server 5 is displayed on the display unit 102 by pressing down the failure display button 104 of the display designation unit 101 of FIG. 18. . When the feature point management number of the display unit 102 is designated, search information for searching for the 3D CAD model having the feature point management number is transmitted from the terminal 200 to the management server 2, and the knowledge is transmitted via the management server 2. The corresponding data is retrieved from the 3D CAD model storage unit 51 of the storage server 5 and transmitted to the management server 2. Further, the knowledge storage database server 4 searches the knowledge storage unit 53 for the presence / absence of defect knowledge information possessed by the feature point management number, and transmits the result to the management server 2. The management server 2 transmits the result to the terminal device 200, and the corresponding 3D CAD model is displayed on the display unit 103 together with an arrow, a feature point management number, or the like as a feature point having a malfunction phenomenon by executing the program of the terminal device 200.

Further, the service personnel can know the accuracy of the round hole from the screen of FIG. 15 of the terminal 200, and the tolerance that is the intention of the design, and the dimensions of the round hole can be obtained by disassembling the actual product. Will be measured. The actual dimensions at that time can also be described in this form. Further, the production process manager of this product confirms this round hole machining process at the production site, and inputs the answer by depressing the countermeasure response button 105 of the display designation unit 101 on the screen of FIG. be able to.

As described above, design, production technology, production, inspection, and service describe the knowledge of the same feature points. The feature point management numbers relate the design, production technology, production, inspection, and service thoughts in each business. In many cases, not only knowledge that design, production technology, production, inspection, and service are linked, but in order to accumulate that knowledge, a method that links the design table with the production table, inspection table, service table, etc. Realization is difficult. By describing the knowledge at the same feature point as in this embodiment, it can be understood that the described knowledge has some relationship. The knowledge storage server 5 has a table with the feature point management number as a key in the knowledge storage database server 4, and this table has a plurality of knowledge and feature point management numbers directly above the feature point management number. It has the structure of the feature point management number immediately below the number. It is difficult to read the necessity of the relationship between the design intention of the designer and the shape drawn by the design. Based on the designer's experience and knowledge, we have drawn the shape as a specific shape that realizes a certain design purpose. By looking only at the drawn shape, we can infer the intention of the designer who designed this shape. That is not something everyone can do. The knowledge management apparatus 1000 can solve such discontinuous knowledge.

It is also difficult to understand how to process and produce by looking at the 3D CAD model. Although you can know the partial shape and material, you cannot understand what processing methods and machines are reasonable for processing the shape without knowledge of manufacturing costs and processing quality. . In other words, in selecting the processing method from the shape, a rational selection decision is made based on the cost and quality based on the production technology knowledge as well as the design intent, and the processing method is determined. Depends on the experience and knowledge of the person. In this way, knowledge and relationships used for human judgment can be described, and judgments and reasons for selection as personal know-how can be computerized and accumulated, thereby making it possible to accumulate manufacturing and design knowledge.

In addition, the knowledge of the knowledge management apparatus 1000 that has already been accumulated can be specified by specifying the similarity range or consistency of any of the materials, plate pressure, hole diameter, diameter tolerance, production plan number, etc., which are the conditions of this processing method. The 3D CAD model of the part in the product can be displayed in the storage server 5 and similar parts can be specified by narrowing down by the same part name or functional purpose. As a result, an increase in the types of parts can be suppressed, and a product design with cost competitiveness can be performed. As described above, for the product designer, the knowledge management apparatus 1000 obtains a similar design structure from the design intent, calculates the manufacturing cost, processes accuracy in actual production, whether there is a defect in the market, and the cause when the defect occurs. , Know a wide variety of knowledge.

In addition, since this knowledge management device 1000 is a 3D CAD model for products, parts, materials, raw materials, molds, and other production equipment, jigs, and tools, as a feature point, the awareness of manufacturing personnel is virtually unlimited. Can be described in a typical 3D CAD model. The feature points can also be input to the 3D data of the CAE analysis result. In the case of the stiffness analysis, for example, feature points that describe the reason for the deformed portion of the designed 3D CAD model are registered. Or, what is noticed or problems caused by the actual spot on the production site is often discarded together with the spot when the problem is solved. Even in such a business, by using the knowledge management apparatus 1000, knowledge of feature points described in the 3D CAD model and knowledge of problems can be accumulated, and knowledge for preventing recurrence can be accumulated.

For example, as an example of a 3D CAD model for products, parts, materials, production equipment such as raw materials and molds, jigs, and tools, as shown in FIG. Describe relationships. In FIG. 19, a feature point 200 and a feature point 201 are described as feature points on the product side. A feature point 200 describes a feature such as a material of the part, and a feature point 201 represents a reference plane of the part. At this time, when the outline of the part is extracted in step ST100, the feature point 300 of the material to be input and the reference plane 301 of the material are described as the feature points. On the other hand, the upper mold 312 and the lower mold 310 that are to be trimmed are designed, and the positioning relationship between the mold, the material, and the part to be processed is described by designing the positioning of the input material as the feature point 311. Can do. Similarly, in step ST101, the positioning relationship can be defined by describing the feature points of the hole extraction relationship. These relationships are often entered in product drawings and model drawings, respectively, but the knowledge management apparatus 1000 makes it easy to confirm the positioning relationship at a time.

A specific description method will be described with reference to FIG. The 3D CAD model of the mold designed by the mold design CAD is processed in advance in the knowledge management apparatus 1000 by the CAD format conversion means and stored in the 3D CAD model storage unit 51. The user selects a 3D CAD model of a mold from FIG. 30 which is a menu screen of the terminal 200, and displays a 3D CAD model of a part produced by the mold. The type and component selection instruction information on the menu screen of the terminal 200 is transmitted from the terminal 200 to the knowledge storage server 5 via the management server 2. In the knowledge storage server 5, the 3D CAD model of the specified mold and part and the respective knowledge information are retrieved and transmitted to the management server 2 . The terminal 200 displays the received information. In FIG. 20, the product model and the model model are separately displayed for convenience, but can be displayed in an overlapping manner. For example, by displaying the feature points assigned to the product model in the right model display section in FIG. 20, it is possible to check the consistency of parts and mold positioning in the mold design and perform the mold design. When feature points are described in the designed mold, as shown in the relationship display unit 170 in FIG. 20, the relationship between the product and the material and the mold, the positioning relationship of outline removal, and the relationship between the drilling of the product and the punch are expressed. Display point relationships. In this case, the feature point description method is registered by a method of grouping feature points.

The process for grouping a plurality of feature points will be described with reference to FIG. This is a method for accumulating knowledge that establishes a positioning relationship with a plurality of feature points as described above. In FIG. 21, feature point 4 indicates a higher-order feature point. These indicate that the feature point 1 and the feature point 2 which are the primary feature points are the secondary feature points 4 having the group A as the group A. Similarly, the feature point 5 indicates a new secondary feature point in which the primary feature point 2 and the feature point 3 are group B.

Further, the feature point 6 is a secondary feature point of the group C by grouping the primary feature point 3 and the secondary feature point 5.

Further, the feature point 7 indicates that the secondary feature point 4 and the secondary feature point 5 are grouped and a tertiary point 7 is newly defined.

In the knowledge management apparatus 1000, the primary feature points are stored in the 3D CAD model, but the primary feature points may be related to other primary feature points as a group of secondary feature points. Many. For this purpose, the secondary feature points, which are the upper feature points, are defined, thereby accumulating knowledge about the relationship between the purpose and the realization means. Furthermore, since it is necessary to be able to describe the upper purpose, the structure is such that arbitrary feature points can be grouped and the upper purpose can be explained by the definition of the upper feature points. Thereby, for example, in the case of cost reduction , apart from the viewpoint of how to make the primary feature points cheap, it is possible to go back to the higher-order objective and consider whether there is a cheaper design structure. At this time, since the lower-level feature points constituting the higher-level feature points can be known at a time, it is possible to more quickly and accurately examine the cost, and the knowledge of other higher-level feature points of the lower-level feature points to be configured From this, you can know the quality and other conditions.

Details will be described with reference to FIG. 22 which is a screen of the knowledge management apparatus 1000. When the program of the knowledge management apparatus 1000 is launched on the terminal 200, the program displays the screen of FIG. By selecting a facility as a 3D CAD model to be displayed from the terminal 200 by a user's operation, and selecting a mold designed for performing the hole machining, the search information is transmitted to the management server 2. The The management server 2 transmits the search information to the knowledge storage server 5, and the knowledge storage server 5 specifies the type 3D CAD model from the search information, and transmits it to the management server 2. At this time, the feature point management number of the type stored in the management information is retrieved from the management information specifying the type of the 3D CAD model of the type. The method of describing feature points in this type of 3D CAD model is the same as in the case of products, and the described feature points are searched in the knowledge storage unit 53 of the knowledge storage server 5 and the results are transmitted.

In the terminal 200, a 3D CAD model of the type, a feature point management number, and its type are displayed on the terminal 200 by processing of a program that displays the received type 3D CAD model, feature point management number, its arrow, head coordinates, line type, and the like. Display arrows.

As a result, the 3D CAD model of the panel part and the mold to be pressed is displayed in the feature point description part 550 of FIG. The user assigns the feature point management numbers 324 and 325 in FIG. 20 to the hole which is the feature point of the component panel, which is given as a result of the feature point description of the punch and die part that opens the press hole. The assigned feature point management number 202 is designated in turn with a pointing device such as a mouse, and the feature point grouping button 330 in FIG. 22 for associating the hole of the product with the processing means is depressed. This processing information is transmitted from the terminal 200 to the management server 2. The management server 2 transmits information on the grouping process to the knowledge storage server 5.

In the knowledge storage server 5, an order determination program for feature points operates and is determined by the following processing logic. First, a feature point in which a feature point is described in the 3D CAD model is set to degree 1. The grouped feature points including the feature points of the Nth order or lower are the lowest order of the feature points constituting the group, and the order of +1 is the order of the grouped feature points. If all the feature points constituting the group are of the same order, the feature point order determination program having the order of the order +1 determines the order of the feature points. In the case of this type, since it is recognized from the information from the terminal 200 that all of the primary feature points are configured, the grouped feature points are determined as secondary feature points.

As a result, secondary feature point management numbers are newly determined, and the feature point management numbers 324 and 325 of the punch and die and the feature point management number 202 of the component panel are stored in order to store the relationship. The feature point management number of the feature point is registered. Further, feature point management numbers 324, 325, and 202 are stored in the secondary feature point management numbers. A feature point management number of the grouped feature points received by the terminal 200 is displayed in a part 158 of FIG. The Nth feature point management number is processed and displayed in the same manner.

In the secondary feature point knowledge input method, the feature point management number is displayed in the feature point description portion 550 of FIG. This instruction is a knowledge input form 157 which is a form for inputting knowledge of a new feature point stored in the knowledge storage server 5 by designating the newly displayed secondary feature point management number in the terminal 200 by operating the mouse. Is displayed on the terminal 200 as shown in FIG. With this operation, the knowledge of the upper feature point is registered by the same input and storage processing as the knowledge registration of the parts in the product.

Further, in FIG. 22, the 3D CAD model of the mold is pressed by depressing the 3D CAD model composite display button 150 by the operation of matching the reference points of the part panel of the terminal 200 and the 3D CAD model of the mold in the feature point description unit 550. On the other hand, a process for converting the coordinates of the component panel into the coordinates of the mold is transmitted to the knowledge storage server 5, and the result of the process of converting the coordinates of the component panel into the coordinates of the mold in the knowledge storage server 5 Send to. It can be received by the terminal 200 via the management server 2 and the 3D CAD model of the mold and the part panel can be displayed in an overlapping manner. Thereby, the user can visually confirm the relationship between the hole of the component panel and the punch of the mold.

This means that when a single production facility is processing many types of parts, it is possible to instantly understand the positioning method of each part relative to the production facility and the processing method and position for each part. This helps to grasp the processing target and the processing method of the equipment, and the designer of the production equipment can examine whether or not the new product can be processed more quickly. Even if the person in charge of the facility is changed, the product processed in the past by the production facility can further retain knowledge of the product being processed and its processing method. In the conventional method, the processing method of the production facility is designed for each product, and each is often individually stored in paper or electronic file. Since the past plan can be accumulated by the knowledge management apparatus 1000 and the entire production process can be displayed, it is possible to quickly examine whether or not the new product can be processed and the effect on the product processing during mass production.

Further, processing information can be easily extracted from the knowledge management apparatus 1000. For example, as in the above example, the search for a part having a hole and the display of the 3D CAD model can be performed by selecting the hole in the feature point classification by the user terminal 200. For example, a search request for a feature point management number in which a hole is stored in the feature point classification is transmitted to the knowledge storage server 5, and the knowledge storage server 5 receives all the holes in the product having the hole as the feature point classification from the knowledge storage database server 4. Extract feature points. The extraction result is transmitted to the management server 2, and the management server 2 transmits this result to the terminal device 200, whereby the program of the terminal device 200 displays the search result on the screen. As a result, the user can display the parts to be drilled in the product and the purpose and quality tolerance of the holes at a time.

This displayed list can be used not only for process planning in production technology, but also with this data as it is as basic information for processing management of the production factory in charge of drilling, using the feature point management number as a key. Therefore, information such as the manufacturing cost and the result of quality inspection can be added to this basic information. Alternatively, it functions as an interface with a system that accumulates existing manufacturing costs and quality inspection results. The measurement results at the production site are measured periodically or continuously. For the system that accumulates the measurement results here, the hole is identified using the feature point management number as a key, and the measurement information of the hole is displayed. can do. In this way, the feature point management number functions not only as a hole but also as an interface with quality, cost, and lead time information of all production processes such as welding, assembly, and machining.

The grouping of feature points described in FIG. 22 is a grouping of feature points of parts and molds, but the same function is used for grouping of feature points of a plurality of parts, for example. FIG. 23 shows a structure for fastening a part with two bolts. FIG. 23 shows bolts 673, assembly holes 671 of fastening objects 670 and 670, fastening destination parts 675, fastening destination holes 676, and fastening nuts 678 as characteristic points related to the bolt fastening structure. The screw fastening portion 600 can be stored in the knowledge storage server 5 as a secondary feature point obtained by grouping these six feature points. The screw fastening portion 601 is also a feature point grouped in the same manner. As a result, the screw tightening torque is registered in the knowledge storage server 5 as knowledge of the secondary feature point management numbers of the screw fastening portions 600 and 601, respectively. Since the person in charge of planning the machining method of each part can share the knowledge of the grouped secondary feature points 600 and 601, the person in charge of examining the machining method of the hole 676 of the feature point 675 is this person. The purpose of the hole is a through hole for tightening the bolt 673, and the tightening torque can be known, and a plan based on that knowledge can be made.

The grouping method is to display FIG. 23 of these parts in FIG. 22 as an example of the screen of the terminal 200, for example, by sequentially specifying the heads 556 of the six arrows in FIG. By pressing the group button 330, grouping information is transmitted. The six feature point management numbers and the grouping processing request command are transmitted from the terminal 200 to the management server 2. The management server 2 transmits the received processing instruction to the knowledge storage server 5. The knowledge storage server 5 sequentially searches the target feature point management numbers, adds new secondary feature point management numbers determined by the knowledge storage server 5 to the respective feature point management numbers, Six secondary feature point management numbers are stored in the lower six feature point management numbers. When the addition process is completed for the six feature point management numbers, the completion message is transmitted to the management server 2. The terminal 200 receives the result and displays the reception result on the screen. As a result, the user can know that the grouping is completed and the secondary feature point management number displayed in the upper feature point management number column of the knowledge input form 157 of FIG. it can. The knowledge input form 157 for the grouped feature point management numbers is acquired from the knowledge storage server 5 in advance as a knowledge input format of the tightening unit, and the user uses the terminal 200 to display the display tightening unit. The attributes such as the name and the tightening torque, and the tightening order in the total number of fastened objects are registered and stored. As a result, the person in charge of processing the object to be fastened can know which holes are screw through holes, and from which hole the designer thinks to perform tightening in order. In addition, the manufacturing cost of each screw tightening portion 600 and screw fastening portion 601 can be calculated, and can be utilized when comparing the manufacturing cost with a fitting method that is a fastening method instead of screw tightening. it can.

With the function to group multiple parts, the 3D CAD model of the tightening part in the product can be displayed, and a list of tightening parts such as bolts, nuts and tightening torque standard values used by the tightening part can be displayed. Can be displayed. Since the feature point management number is also displayed in this list, this feature point management number serves as an interface with an external system that accumulates actual tightening torque values measured from the tightening device, and displays torque monitoring. can do. In addition, it is possible to display the manufacturing cost from the tightening time and the depreciation cost of the automatic machine in the list of the tightening parts.

Furthermore, as shown in FIG. 24, grouping regarding the quality of feature points can be performed. For example, it is possible to register grouping when quality control of gaps between a plurality of parts is performed. In the registration method, a 3D CAD model of a product is selected from the terminal 200, and a plurality of parts related to the accuracy management are selected in order to manage the accuracy of the gap 130 in the product. Displays the 3D CAD model of the part.

On the displayed screen, the screw tightening portions of the respective parts are already grouped, and four grouped secondary feature points 111, 112, 121, 122 are displayed. The user controls the accuracy of the gap between the part 110 and the part 120, draws a line with an arrow as the feature point 130 in the gap, and provides, for example, quality, gap direction X, Y, Z dimensions, tolerance as an input form of knowledge about the quality. Data is input to the knowledge input form displayed from the knowledge storage server 5 that prompts input. The input information is stored in the knowledge storage server 5.

Here, the primary feature point 130, which is a clearance to be controlled by the user's operation from the terminal 200, is designated as the feature point 115 indicating the assembly reference hole 126 of the component 110 and the end surface of the component 110 on the clearance side. And a feature point 125 indicating the assembly reference hole 124 of the part 120 and an end surface on the gap side of the part 120, a feature point 127 indicating the pitch of the holes 124 and 126 of the attachment destination part, and a feature point grouping button Is recorded in the knowledge storage server 5 as information indicating that dimensional management from the assembly reference holes of the two parts is an element of accuracy management.

Simultaneously with this storage, the information input by the user is displayed in the lower table of FIG. 24 together with the reception of the feature point management number determined by the knowledge storage server 5. For this table, the user inputs gap direction X, Y, Z dimensions and tolerance data from the terminal 200. In this way, the feature points are associated with the feature points of the related elements, and necessary data can be stored. As a result, by specifying the feature point 130, a list of feature points which are conditions for realizing the feature point is displayed.

If the feature point is displayed for the part 110, the feature point 115 of the end face is displayed on the 3D CAD model of the part 110 as the feature point, and a management part necessary for managing the gap between the part 110 and the part 120 is displayed. Can do. This knowledge information can be obtained via a network even in the production process in the company that produces the parts 110 or an external supplier, and can be used for quality planning and quality management including the supplier.

Further, as shown in FIG. 25, the manufacturing cost can be calculated and displayed in the feature point list for each processing classification in units of functions. In FIG. 25, a search target specifying unit 181, a result display unit 180, and a display unit 182 for displaying the corresponding 3D CAD model are provided. As a result, it is possible to recognize which processing cost is high for each function, and it is possible to encourage consideration of alternatives. It is effective for cost reduction activities because it can be aggregated not only by manufacturing cost of parts but also by functional unit or processing unit. It is also possible to aggregate this function for the same function of a plurality of products, and as a result, it is possible to know a manufacturing cost difference due to a difference in product design structure.

Also, by using the feature point management number, as the production status of the same product in the global production factory, by displaying information such as hole machining accuracy and tightening torque actual value of the same feature point management number on the same graph, Differences between factories can be easily displayed. The manufacturing cost and quality indicators as a whole can be correctly calculated and displayed by the unified classification and tabulation method registered by the technical classification management means 72. In FIG. 26, the search target specifying unit 190 acquires the search target from the knowledge storage unit 53, and the production cost for each product for each production line is listed in the total result display unit 191, so The example of a screen which grasps the above and promotes cost reduction is shown. The display unit 192 on the right displays a 3D CAD model that is a target by designating a processing category of a product of a specific production line.

Such registration of the aggregation method is defined by a function in the technical classification management means 72. This is because unified classification and calculation formulas using words and words need to be handled as one. In the technical classification registration screen of FIG. 10, a calculation formula registration button is arranged beside the column for language registration. The calculation formula can be stored in the word storage unit 52 by this method. For example, the calculation formula can be registered by using a registered technical language having a data structure as shown in FIG. This also establishes a relationship between words. Generally, each person in charge uses free words, so even a simple expression may look different. This makes it difficult to aggregate the costs, quality, and lead times grasped in detail at the production site and make them visible to management. Even for complex scientific calculations, the interpretation of the summary results is easy if there is a unified operation and understanding of the meaning of the technical language described in the calculation formula.

Such knowledge is more effective in companies that repeatedly improve functions by changing product models. In the product development / production process, there are many cases where operations are performed while correcting standard documents such as forms, lists, and specifications used in past product development / production. The most difficult part of organizing the item names and their specific data used in the documents described in these documents is that the definition of the words used for the item names is ambiguous and items used between organizations. The meanings of the names are different, and the item names are not connected directly, and the item names used in the examination and analysis work are tacit knowledge or memos, which is why it is difficult to accumulate and communicate knowledge. Yes.

In the knowledge management apparatus 1000, this problem is solved by the technical classification management means 72, and knowledge is transferred to the 3D CAD model so that knowledge sharing means for changing the person in charge or global knowledge sharing can be easily understood visually. The description method can be used to define the relationship between multiple knowledges, and even knowledge that is not connected between item names can be obtained by describing the knowledge at the same feature points of the 3D CAD model. I can do things.

The amount of knowledge increases from the product development stage. When designing a function, multiple ideas are considered and evaluated. In addition, for the ideas that have been narrowed down, improvement of product reliability is studied using FMEA (failure mode and effects analysis) and FTA (fault tree analysis) techniques. Multi-faceted considerations such as processability, cost, and quality are added by design reviews such as production requirements for product design. Until this stage, the knowledge of many experts about manufacturing is gathered. From this stage, solutions to the concerns and concerns that have been raised so far are gradually developed, and the degree of completeness of product design increases. In other words, the completeness of the 3D CAD model is increased. When the 3D CAD model is completed, the production method is determined, and the manufacturing cost planning and quality planning goals are achieved. In producing this designed product, management items in production are specified. In this way, knowledge is generally accumulated from the development stage, and knowledge gradually converges to what is necessary for production management before production. This means that the use of the knowledge management apparatus 1000 is effective for the purpose of accumulating the accumulated knowledge in the product development stage, and the management items for production are determined from the accumulated knowledge. Furthermore, this accumulated knowledge at the development stage is the cornerstone of problem solving in mass production services. Moreover, by using it as a template or master data for the next product development, it is possible to support design thinking and contribute to efficiency while improving the quality of the design.

Therefore, it is possible to use this feature point describe (knowledge description) to the subject and the progress of technology decision. The screen shown in FIG. 28 shows an example, and is displayed on the terminal 200 in FIG.

The function shown in FIG. 28 is a function in which each person in charge describes a feature point with respect to the 3D CAD model in three judgment categories, for example, a problem point, a holding point, and an approval point. The description of the feature points may be the same method as the knowledge description described so far. For example, a line can be drawn with an arrow to describe the technical knowledge of the feature point, and at the same time, the technical judgment classification of the above three problems, the reservation point, and the approval point can be registered. By using this method from the product development stage to production and service, it is possible to grasp numerically the amount of technical problems and the progress of solutions in each development phase.

Also, by describing problems with different experts in the same feature point, the department that raised the problem for the feature point can be identified by the login ID etc. on the terminal 200, and the trigger for the solution between the departments The problem solving speed can be accelerated. For example, the number of problems and the change in technical judgment can be shown as a transition graph in frequency. From this graph, it is possible to know the amount of problems that each department has at the development stage, and it is also possible to grasp the solution status with a time series graph.

Also, by inputting technical judgments into feature points, the structure and concept of feature points will be reviewed, leading to a review of knowledge standards in the organization. As a result, the knowledge management apparatus 1000 can store more reliable knowledge.

FIG. 29 shows a flowchart in the case where knowledge management apparatus 1000 registers and manages knowledge. In step S1, the 3D CAD model stored in the 3D CAD model import management server 1 saved from an external system such as CAD or PLM is lightened by using the menu screen shown in FIG. Is sent to the management server 2, and the management server 2 receives the command and stores all the 3D CAD stored as product components in the 3D CAD model import management server 1 program. Convert the model data format. When the conversion is completed, the 3D CAD model of the converted component part of the product is transmitted to the knowledge storage server 5 by a registration command from the terminal 100 to the knowledge storage server 5. In the knowledge storage server 5, the CPU program of the knowledge storage server 5 is activated and compared with the import record of the 3D CAD model of the product, and whether it is the 3D CAD model of the product or part to be imported for the first time is given by the external system. Compared with management information such as product number, product name, and component table configuration code assigned to specify one 3CAD model, the 3DCAD model that is not captured in the 3DCAD model storage unit 51 is batch processed. The 3D CAD model acquisition management server 1 sequentially acquires and stores the acquired 3D CAD model in the 3D CAD model storage unit 51 of the knowledge storage server 5. In this program, the data with the acquisition record in the 3D CAD model storage unit 51 is a process for finding the shape difference between the already acquired 3D CAD model and the 3D CAD model acquired this time, as will be described later. Will continue.

In step S2, the 3D CAD model based on the request specified from the menu screen of FIG. 30 displayed on the terminal 100 is received from the knowledge storage server 5 to the terminal 100 and displayed on the display unit. Further, according to the instruction from the terminal 100, the classification of the word storage unit 52 and the words of the function classification and specification expression designated by the user's selection operation from the words are displayed on the display unit, and are displayed on each of the 3D CAD models. In addition, an operation for designating appropriate function classification and specification expression words for the 3D CAD model is performed. When this designation information is transmitted to the knowledge storage server 5, the CPU program of the knowledge storage server 5 performs a process of creating a unified part name code with a combination of this function classification and specification expression. The unified part name code is determined to be unique in the word storage unit 52, and the unified part name and the unified part name code are stored in the word storage unit 52.

Also, in step S3, after step S2, the displayed 3D CAD model is separated from management information such as a product number, product name, and component table configuration code assigned to specify one 3CAD model assigned by an external system. The unified part name code used in the quality management apparatus 1000 is added and stored in the 3D CAD model storage unit 51 of the knowledge storage server 5. Thus, the 3D CAD model is associated with the knowledge storage unit 53, which is a database for storing knowledge, by the unified part name code. In addition, the table for storing the unified part name code is not only classified by function, but also by registering the unified part name code in the front, rear, upper, lower, etc. table, which is the position inside the product. You can also This is used in a program when the knowledge management apparatus 1000 performs cost aggregation and search processing by a plurality of classifications managed by an organization or a company such as a function or a part in a product.

In step S 4, a selection instruction such as a classification name by the menu of FIG. 30 is transmitted from the user terminal 200 and received by the knowledge storage server 5, and the 3D CAD having the information received by the knowledge storage server 5 is received by the knowledge storage server 5. In order to specify the model, the unified part name code is identified from the classification table of the word storage unit 52 given in step S2, and the 3D CAD model storage unit 51 is searched for data for the 3D CAD model corresponding to the unified part name code. To the terminal 200.

At this time, for example, when a unified part name and a feature point classification such as a hole and a material are specified from the menu of the terminal 200, the search information is received by the management server 2, and the management server 2 knows the search information. Transmit to the storage server 5. The knowledge storage server 5 extracts from the knowledge storage unit 53 the product name, unified part name code, and feature point management number having the relevant feature point classification of the received information, and transmits the information to the management server 5. The received information is displayed on the display unit by the terminal 200. Further, when the request information for displaying the 3D CAD model having the feature point management number is transmitted from the terminal 200 to the management server 2, the management server 2 transmits the information to the knowledge storage server 5. . The knowledge storage server 5 retrieves the 3D CAD model from the feature point management number, transmits the 3D CAD model to the management server 2, the management server 2 transmits to the terminal 200, and the display unit displays the 3D CAD model by the display program of the terminal 200. The corresponding 3D CAD model is displayed. In this way, a similar part or a part having a similar structure can be displayed. FIG. 31 shows a flowchart of a process for searching for similar parts together with a data structure example.

In step S6, the management server 2 receives request information of the user terminal 200 such as an arbitrary product name, an arbitrary unified part name, and a feature point classification for parts having a similar structure, and the corresponding 3D CAD model and its feature points. By receiving the extraction result in the knowledge storage server 5 such as the management number and the knowledge management number, and transmitting the result to the terminal 200, the user can compare with the part structure of the product to be examined.

The user makes a technical judgment for each feature point of the component to be examined by referring to the knowledge of the component having the similar structure. A display example of this similar structure is shown in FIG. In response to a request from the terminal 200, a stored table of technical judgment is displayed by the program of the terminal 200, like the display unit 780. At the right end of FIG. 32, the history of technical judgment input for each phase is displayed as a symbol. For example, a circle indicates that there is no problem, and an underbar indicates that no technical judgment is made. Models 1, 2, and 3 are past products, and model X is a product for which the user makes a technical decision. The terminal 200 receives the input result in the technology judgment input field at the right end of the model X, and transmits the input information to the management server 2, which is stored in the technology judgment storage unit 54 of the knowledge storage server 5. .
In step S6, for example, the technical judgment is classified into approval, suspension, and problem.

When the technical judgment is input, the program of the terminal 200 displays the screen of FIG. Information for obtaining the feature point management number is transmitted to the management server 2 by the feature point input operation of the terminal 200. The management server 2 transmits a request for determining a feature point management number to the knowledge storage server 5, and the knowledge storage server 5 transmits a new unique feature point management number to the management server 2. The management server 2 transmits the feature point management number to the terminal 200, and the terminal 200 displays the feature point management number on the display unit of FIG. Thereafter, for example, an approval , hold, and problem code indicating a technical judgment is transmitted to the feature point to be approved together with the feature point management number and the development phase code by an input operation of the terminal 200, and the technology is transmitted via the management server 2 to the technology point. Stored in the judgment storage unit 54. Knowledge description is performed on the feature points of the part to be examined, and the result of examination of the part of the new product is stored in the technology judgment storage unit 54 of the knowledge storage server 5 in step S7. In step S7, the user is requested by the terminal 200 to describe the details of the reason for the technical judgment, the background knowledge of the judgment, the contents of the countermeasure, and the description of the countermeasure result, and the input result is also stored in the technical judgment storage unit 54 together with the feature point management number. The In step S7, a knowledge diversion process described later is also executed.

Here, in step S7, when the management server 2 receives a feature point management number having a hold or problem classification, it is stored in the management information of the original 3D CAD model from the unified part name code to the knowledge management device 1000. Obtain designer information such as e-mail address, obtain e-mail address of problem pointer from product name, part name, content of problem and user management information held by access control unit, and cause problems for designer of 3D CAD model The instructor's name is specified and the technical judgment result is automatically transmitted.

As a result, in step S8, each user can grasp the approval, problem, and hold status for each feature point from the terminal device 200 in the business field. It promptly communicates with whom in the organization who should have a technical meeting, and as a result, contributes to examining the solution direction by methods such as meetings and review meetings.

In step S9, the knowledge standard is reviewed. When a request that uses the same unified part name code as the feature point management number determined to be a problem and the same purpose as the search condition is transmitted to the management server 2 by selecting the menu of the terminal 200, the management server 2 returns to the knowledge storage server. The search condition is transmitted to 5. The knowledge storage server 5 executes a process from the knowledge storage unit 53 using the same unified part name code as the feature point management number and the same purpose as a search condition, and the knowledge storage server 5 receives a standard corresponding to the request from the knowledge standard storage unit 55. The knowledge data is searched, and the two search results are collected and transmitted to the management server 2. When the terminal 200 receives this knowledge standard, the program of the terminal 200 is displayed on the display unit. If the knowledge standard does not exist, a message that there is no corresponding data from the knowledge standard storage unit 55 is displayed on the display unit of the terminal 200 via the management server 2.
Based on the user's judgment, the input information of the knowledge that the specification of the feature point management number to be used as the technical standard or the standard is reviewed from the information displayed on the display unit is transmitted to the management server 2. The management server 2 transmits it to the knowledge standard storage unit 55 together with this feature point management number, and stores it as standard knowledge in the knowledge standard storage unit 55.

As a result of the technical judgment, the technical judgment feature point management number 570 is displayed below the knowledge management number 566 in the 3D CAD model by the program of the terminal 200 on the screen of the terminal 200 as shown in FIG. Since the same feature point management number is judged from a plurality of knowledge, a plurality of technical judgments are displayed in the lower order as shown in FIG. For technical judgments without knowledge management number registration, knowledge management numbers are not displayed.

Further, as shown in FIG. 34, when the feature point management number has an upper feature point, the feature point management number and the upper and lower feature point management numbers are retrieved from the knowledge storage server 5 as a result of the similarity search. 200 3D CAD models are displayed. When the user performs an operation of specifying the upper or lower feature point management number on the terminal 200, the information is stored in the knowledge storage unit 53 via the management server 2 and the program operation of the CPU of the knowledge storage server 5. Search and specify the unified part name code of the product having the upper or lower designated feature point management number as an attribute. As a result, the 3D CAD holding the specified unified part name code from the 3D CAD model storage unit 51 The model is transmitted to the management server 2. The result is displayed on the screen by the program processing of the terminal 200.

As described above, the user can increase the certainty of the technical judgment by acquiring the upper or lower knowledge obtained by searching for similar parts by operating the terminal 200.

In FIG. 35, the feature points are created from two aspects of knowledge and technical judgment. As the feature points, upper feature points are created. This relationship will be described. A feature point management number is expressed by a combination of alphabets and numerals, and alphabet K is knowledge, and a unique number assigned by the knowledge management server 5 as a result of input from the terminal 200 is expressed by numerals. On the other hand, the alphabet D represents technical judgment, and the technical judgment feature point management number assigned by the knowledge management server 5 based on the input result from the terminal 200 is expressed by numbers. The alphabet T is a feature point number. Here, T1 indicates a feature point shared by knowledge and technical judgment.
Circles are feature points of knowledge, double circles are upper feature points, and K3 indicates a higher knowledge concept of K1 and K2. On the other hand, a square mark is a technical judgment feature point, a double square is an upper feature point, and D3 indicates a higher technical judgment of D1 and D2.

With this structure, technical judgment and knowledge are registered in the feature point T1. From the feature point T1, K3 of the higher knowledge and D3 of the higher technology judgment can be searched. Further, the lower knowledge K1 and K2 related to the upper knowledge K3 can be searched. The technical judgments D1 and D2 related to the upper technical judgment D3 can be searched. This makes it possible to understand the high-level knowledge that is the design intention of the feature point of the 3D CAD model that has been technically determined, knows the low-level knowledge that realizes the design intent that is the high-level knowledge, and what department is in what kind of technology You can search to see if you are making a decision. The knowledge storage server 5 extracts the feature point management number from the knowledge storage unit 53 and the technology judgment storage unit 54 in response to a search request from the terminal 200, so that the knowledge and technology judgment belonging to the feature point management number are higher. And the lower feature point management number are retrieved, transmitted to the terminal 200, and displayed on the terminal 200. Thereby, the user can search knowledge and technical judgment from both directions, and can consider more standard knowledge.

Knowledge can be diverted from this search result. FIG. 36 shows a flowchart of knowledge diversion after searching for knowledge. There are cases where the user diverts knowledge based on the purpose, or already knows the feature point management number of the knowledge to be diverted. Therefore, in this flowchart, two flows of step S20 and step S21 are described.

In step S22, the knowledge storage server 5 identifies a unified part code that matches the purpose from the purpose, and performs a process of extracting a list of feature point management numbers stored in the unified part code from the first to the Nth order. The processing result is displayed on the terminal 200. The user designates a feature point management number for the displayed list.

All of the upper and lower knowledge and technical judgment held by the specified feature point management number are extracted from the knowledge storage unit 53 and the technical judgment storage unit 54, and the knowledge storage server 5 transmits the detailed contents thereof. The terminal 200 receives this information and displays it on the screen.

If the displayed content needs to be corrected, the displayed knowledge is corrected by an input from the correction screen on the terminal 200 and transmitted to the knowledge storage server 5. Further, it diverted knowledge which stores the state of the diversion by the ON flag for flow. In the diversion source 3D CAD model and the diversion destination 3D CAD model, since the coordinates 552 that are the positions of the feature points do not indicate the correct positions, the position of the arrow of the feature point is corrected by the editing function. The information thus corrected is stored in the knowledge storage server 5 as knowledge of the 3D CAD model of the diversion destination by the user's operation using the terminal 200.

By correcting the knowledge standard, the problem of the feature point of the part of the new product can be solved, and the feature point to change the technical judgment to approval is the operation to approve the technical judgment in step S7 of FIG. 29 and change the progress to completion. 200 and the input is transmitted from the terminal 200 to the management server 2. The management server 2 receives the information and transmits it to the technology judgment storage unit 54. The technology judgment storage unit 54 stores the phase classification, the input date, and the name of the input person in the technology judgment storage unit 54. On the other hand, if the knowledge standard cannot be changed in step S10, it is solved by changing the design. In step S14, the designer changes the 3D CAD data on the external system.

Further, the pending technical judgment is changed from a problem to an approval point through the meeting and the review meeting in step S8. The technical judgment in the related organization is a request for acquiring knowledge such as the processing method, quality, cost, lead time, and safety of the production stored in the feature point management number by the designation operation of the feature point management number of the terminal 200. Is transmitted to the management server 2. The management server 2 transmits the received request to the knowledge storage server 5, and the knowledge storage server 5 executes database search processing according to the request. The search result is transmitted to the management server 2, and the management server 2 transmits the search result to the terminal 200. The terminal 200 displays the search result. By confirming the displayed search result, the user concludes with a comprehensive technical judgment of the related organization regarding the feature point management number.
As a result, the technical judgment classification of the feature point management number is changed from the hold to the problem or the approval point, and is input to the terminal 200 by the user. The result is transmitted from the transmission unit of the terminal 200 to the management server 2, and the management server 2 similarly uses the received technical judgment result as the product, part name, feature point management number, technical judgment classification, phase classification, and input date. The date and the name of the input person are transmitted to the technical judgment storage unit 54, and the technical judgment storage unit 54 adds this information and stores it. This is used to display the technical judgment history of the feature point management number. Ideally, all problems and concerns in the development phase are resolved before mass production. Therefore, in the mass production stage, the feature points of the 3D CAD model are also stored in the technical judgment storage unit 54 as management points in the production stage in step S12. The development stage knowledge is transferred to the management point in production, and the search result of the technology determination storage unit 54 is displayed on the terminal device 200 by the operation of the terminal device 200 in the same manner as described above. To do.

In this way, a series of technical judgments and registrations are performed on the feature points of all parts, the design review of the product design in one phase is completed, and the knowledge is stored in the knowledge management apparatus 1000. There are a plurality of phases such as a design concept stage, a design stage, a prototype stage, and a mass production prototype stage.

Further, since design changes frequently occur in the product development phase, it is necessary to inherit the knowledge already stored for the design changes of product parts and facilities stored in the knowledge management apparatus 1000. Therefore, FIG. 37 shows a flowchart of processing for checking the shape change of the 3D CAD model and clearly indicating the feature point to the user when there is a shape change. This flowchart is executed in step S1 of FIG.

The method of confirming the shape difference of the CAD which is an external system is mainly a method of displaying all the portions having a shape change. In the knowledge management apparatus 1000, the part where the feature point is described with respect to the shape is the part that the user has paid attention to, and is the coordinate where knowledge description and technical judgment have been performed. Therefore, in the flowchart of FIG. 37, the knowledge storage server 5 searches the knowledge storage server 5 for the coordinates of the feature points already stored in the knowledge storage server 5, and whether or not there is a change based on the consistency with the coordinates after the shape change. Process to identify.

As shown in FIG. 38, the knowledge management apparatus 1000 calculates the in-house processing cost based on the processing technology used for production by arranging the product development timing in chronological order based on the processing technology described in the feature points of each part. Thus, it is also possible to display the level of technological progress using the history of processing technology as an index of cost, quality, etc. for each part of each product.

This knowledge management apparatus 1000 can compare information between products side by side by describing knowledge using a uniform technical language by the technology classification management means 72 even for a plurality of products. This makes it possible to display processing operations in a unified word expression for the process of producing a plurality of products. As a result, it is possible from the knowledge management apparatus 1000 to recognize the same work even if the products are different, and prevent cost calculation mistakes and work training due to work name inconsistencies due to various descriptions by multiple persons in charge. It is possible to improve the efficiency of the entire manufacturing company, such as the correctness of the plan, creation of a correct plan list of necessary equipment, jigs and tools.

With regard to information security, data management is performed in units of feature point management numbers, which are feature points that are further subdivided compared to the amount of information that has been provided outside the company in units of drawings. Compared to information disclosure in units of drawing numbers in the case of drawings, the access control server 6 in FIG. 2 can disclose only necessary processing technology information and its portion. Furthermore, information disclosure based on the level of higher feature points, function classification, or the like may be added. In addition, unlike the method of distributing drawings, the security level can be maintained at a higher level than the method of distributing drawings by storing logs for identifying companies and individuals who have searched for information.

Many companies use two-dimensional drawings when ordering parts production from external suppliers. Product development and design enterprises are proceeding with design by CAD, but they distribute drawings to outside suppliers and request production. In order to control the quality and cost of parts production overseas, such as global production expansion, to transmit knowledge that cannot be described in two-dimensional drawings, such as technical instructions and other electronic forms Is done. The knowledge management device 1000 can be used as a method for transmitting technical information in global design and production connected by various networks, and it is considered that paper distribution by drawings and technical instructions can be eliminated.

The business method in the manufacturing company has made design and production engineering work more efficient by using CAD. However, the 3D CAD user is often used only by a limited person in the company. Quality and cost planning and design, production technology processes and equipment design, etc. remain veteran-dependent methods. There are many engineers involved in these operations in manufacturing companies. There is a need to improve the efficiency of engineering work and increase the productivity of planning work. The knowledge management apparatus 1000 improves productivity in this field and enables accumulation of knowledge such as know-how to be shared by engineers.

In the manufacturing industry that manufactures heavy industries, plants, shipbuilding, vehicles, electrical, electronic products, etc., the present invention is used for global product development, production, and service operations for management and human resource development within companies, corporate groups, and between companies. It can also be used for acceleration and innovation.
