Can do.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 2 is a diagram showing a system configuration example according to the embodiment of the present invention.
As shown in the figure, the server 10 is connected to terminals 31 to 33 via a network 40 which is, for example, a LAN (Local Aria Network). The server 10 is equipped with a design support program and supports a designer who designs a three-dimensional model.

Terminals 31 to 33 are terminals used by the designer. The designer accesses the server 10 using the terminals 31 to 33 and models a three-dimensional model of the product.
A hardware configuration of the server 10 will be described.

FIG. 3 is a diagram illustrating a hardware configuration example of a server to which the design support program of the present invention is applied.
As shown in the figure, the entire server 10 is controlled by a CPU (Central Processing Unit) 10a. A random access memory (RAM) 10b, a hard disk drive (HDD) 10c, a graphic processing device 10d, an input interface 10e, and a communication interface 10f are connected to the CPU 10a via a bus 10g.

  The RAM 10b temporarily stores at least a part of an OS (Operating System) program executed by the CPU 10a and an application program for modeling a three-dimensional model of a product. The RAM 10b stores various data necessary for processing by the CPU 10a. The HDD 10c stores the OS, application programs, various data, and the like.

  A monitor 10h is connected to the graphic processing device 10d. The graphic processing device 10d displays an image on the display screen of the monitor 10h in accordance with a command from the CPU 10a. A keyboard 10i and a mouse 10j are connected to the input interface 10e. The input interface 10e transmits a signal transmitted from the keyboard 10i or the mouse 10j to the CPU 10a via the bus 10g.

The communication interface 10f is connected to the network 40. The communication interface 10 f communicates with the terminals 31 to 33 via the network 40.
With the hardware configuration as described above, the processing functions of the present embodiment can be realized. The terminals 31 to 33 also have the same hardware as that shown in FIG.

FIG. 4 is a functional block diagram of the server.
As shown in the figure, the server 10 includes an input unit 11, a modeling unit 12, a modeling check unit 13, a display unit 14, a processing condition check unit 15, a processing method database 16, a processing method input table 17, a manufacturer processing database 18, and a corrected shape. A database 19, a manufacturing request destination database 20, and a manufacturer database 21 are included. Each database and table are constituted by, for example, the storage devices of the RAM 10b and the HDD 10c shown in FIG.

  The processing method database 16 is a database in which processing methods for processing products are stored. The designer designates a processing method for manufacturing the product from the processing methods stored in the processing method database 16.

FIG. 5 is a diagram illustrating a data configuration example of the processing method database.
As shown in the figure, the processing method database 16 has columns for molding and cutting. In the mold forming column, a processing method related to mold forming is stored. In the column of cutting, a processing method related to cutting is stored.

  In the example of the figure, the mold forming column stores mold (die) machining, forging, and sheet metal machining methods. In the column of machining, machining methods for milling, lathe and drilling are stored.

  The processing method input table 17 is a table that stores a processing method designated by the designer and specific values related to the product shape when a product is manufactured by the processing method. The processing method and the specific value are input from the terminals 31 to 33 when the designer models a three-dimensional model of the product. A plurality of processing methods and specific values corresponding to them can also be stored. In this case, the processing methods and specific values are stored in the processing method input table 17 in the order in which the products are processed.

FIG. 6 is a diagram illustrating a data configuration example of the processing method input table.
As shown in the figure, the machining method input table 17 stores a machining method designated by the designer from the terminals 31 to 33 and its specific value. In the example shown in the figure, mold processing is stored as a processing method. Moreover, the specific value regarding the product shape in the case of processing a product by mold processing is stored. Stored are specific values related to the taper angle, the taper direction, the meat stealing shape / dimension, and the edge processing shape / dimension.

  The manufacturer processing database 18 is a database in which processing know-how of a manufacturer that manufactures a product is stored for each manufacturer. The processing know-how is, for example, processing information such as R processing of product corners and what dimensions can be achieved.

  The corrected shape database 19 is a database in which the shape of the product corrected by the designer is stored. When the shape of the product modeled by the designer cannot be actually realized (processed) by the specified processing method and specific value, the designer corrects the shape of the product. The product shape corrected by the designer is stored in the corrected shape database 19.

  The manufacturing request destination database 20 is a database in which manufacturer information that can be used to request manufacturing of products is stored. The manufacturing request destination database 20 stores, for example, information on manufacturers who have contracted product manufacturing and manufacturers who have requested manufacturing in the past. The designer can make a manufacturing request for a product to the manufacturer stored in the manufacturing request destination database 20.

  The manufacturer database 21 is a database that stores manufacturer information other than manufacturers who can request the manufacture of products. The manufacturer database 21 stores, for example, information on manufacturers who are not contracted to manufacture products and manufacturers who have not requested manufacturing in the past. The designer makes a manufacturing request to the manufacturer stored in the manufacturer database 21 when the manufacturer who can request the manufacturing is not stored in the manufacturing request destination database 20.

The input unit 11 receives data input by the designer to the terminals 31 to 33. The input unit 11 stores the received data in an appropriate database and table.
The modeling unit 12 models a three-dimensional model of the product according to the operation of the designer's terminals 31 to 33.

  The modeling check unit 13 determines whether the shape modeled by the modeling unit 12 can be realized by the machining method and the specific value specified by the designer. Specifically, it is determined whether or not the designer's modeling can be realized with the machining method and the specific value stored in the machining method input table 17. At this time, the modeling check unit 13 refers to the manufacturer processing database 18 and determines whether the modeling intended by the designer can be realized according to the manufacturer.

  When the modeling check unit 13 determines that the designer's modeling cannot be realized, the modeling check unit 13 highlights an edge or face of the portion that cannot be realized. The determination as to whether or not the modeling shape can be realized is performed for each shape creation operation (one operation) of the product by the designer. Therefore, when the modeling check unit 13 determines that the designer's modeling cannot be realized, the modeling check unit 13 highlights the portion where the shape creation operation was performed immediately before.

  After the highlight display, the modeling check unit 13 acquires a shape similar to the shape from the corrected shape database 19 according to a request from the designer. Alternatively, it accepts modeling corrections directly from the designer according to the requirements of the designer. When the modeling check unit 13 receives a modeling correction from the designer, the modeling checking unit 13 stores the corrected modeling shape in the corrected shape database 19.

  The display unit 14 displays the contents of a predetermined database and table and the product shape modeled by the modeling unit 12 on the monitors of the terminals 31 to 33. Further, the display unit 14 highlights the product being modeled in accordance with an instruction from the modeling check unit 13.

  The processing condition check unit 15 selects a manufacturer that can process the product for which modeling has been completed with reference to the manufacturing request destination database 20. At this time, referring to the manufacturer processing database 18, a manufacturer that can realize the modeling shape, that is, a manufacturer that can process the product is selected. In addition, when the manufacturer that can process the product is not stored in the manufacturing request destination database 20, the processing condition check unit 15 refers to the manufacturer database 21 and selects a manufacturer.

Next, the operation of the server 10 in FIG. 4 will be described using a screen example displayed on the monitors of the terminals 31 to 33.
The display unit 14 of the server 10 refers to the processing method database 16 and displays a processing method for processing the product on the monitors of the terminals 31 to 33. The designer designates a processing method when manufacturing the product according to the monitor. Further, specific values for realizing the product shape by the designated processing method are input to the terminals 31 to 33. The input unit 11 receives the machining method and the specific value designated by the designer from the terminals 31 to 33 and stores them in the machining method input table 17.

The modeling unit 12 models a product according to the operation of the designer's terminals 31 to 33.
The modeling check unit 13 determines whether or not the shape modeled by the modeling unit 12 can be realized by the machining method and the specific value stored in the machining method input table 17. When the modeling check unit 13 determines that the designer's modeling cannot be realized, the modeling check unit 13 highlights the edge or face of the portion that cannot be realized on the monitors of the terminals 31 to 33.

FIG. 7 is a diagram illustrating a screen example of a terminal that displays a highlighted product.
A screen 51 shown in the figure shows a screen example displayed on the monitors of the terminals 31 to 33. On the screen 51, a product 51a modeled by the designer is displayed.

  When the modeling shape of the designer cannot be realized with the specified processing method and specific value, the portion is highlighted (the bold line portion in the figure). For example, assume that drilling is selected as the processing method. Further, it is assumed that the processing method input table 17 registers that the surface of the joint portion between the lower cylinder and the upper cylinder of the product 51a is vertical. In this selected drilling process, when the joining portion has R, and a vertical surface cannot be realized, a highlight display as shown in the figure is performed. As a result, the designer can know an unworkable part of the product 51a.

  When the modeling check unit 13 determines that modeling cannot be realized with the processing method and the specific value specified by the designer, the modeling check unit 13 acquires a shape similar to the shape from the corrected shape database 19 according to the request of the designer. . Alternatively, it accepts modeling corrections directly from the designer according to the requirements of the designer.

FIG. 8 is a diagram illustrating a screen example of a terminal that receives a request from a designer.
As shown in the figure, a screen 52 is displayed on the monitors of the terminals 31 to 33. On the screen 52, buttons 52a to 52c are displayed. When pressed by the designer, the button 52a displays a shape that can be processed, similar to the shape of the highlighted product 51a in FIG. When the button 52b is pressed by the designer, it accepts a modeling correction directly from the designer. When the button 52c is pressed by the designer, the highlight display is ignored and the modeling of the next process is accepted. The button 52c is effective when the designer knows that the product 51a being modeled can be processed in the modeling after the next process even if it is determined that the product 51a cannot be processed in the current process.

FIG. 9 is a diagram illustrating a screen example of a terminal displaying a similar shape of a product.
A screen 53 shown in the figure shows an example of a screen displayed on the monitors of the terminals 31 to 33. The screen 53 shows shapes 53a to 53c when the button 52a is pressed in FIG. When the button 52 a is pressed, the modeling check unit 13 acquires the shapes 53 a to 53 c similar to the product 51 a from the corrected shape database 19 and displays them as shown on the screen 53.

  In the shape 53a, as described above, the surface of the joining portion of the upper and lower cylinders is made vertical by drilling, so that the joining portion is a square groove relief. In the shape 53b, the joint portion is an R groove escape. In the shape 53c, the R groove clearance is larger than that in the shape 53b. The designer can continue modeling by selecting the shapes 53 a to 53 c displayed on the monitors of the terminals 31 to 33.

  In FIG. 8, when the button 52 b is pressed and the highlighted display portion is corrected by the designer, the modeling check unit 13 stores the corrected modeling shape in the corrected shape database 19.

FIG. 10 is a diagram illustrating a screen example of the terminal when the modified modeling shape is registered in the database.
When the highlight display portion of the product 51a is directly corrected by the designer, a screen 54 is displayed on the monitors of the terminals 31 to 33 as shown in the figure. Buttons 54 a and 54 b are displayed on the screen 54. When the button 54 a is pressed by the designer, the corrected modeling shape is stored in the corrected shape database 19. When the button 54 b is pressed by the designer, the corrected modeling shape is not stored in the corrected shape database 19.

  In addition, when the button 52b in FIG. 8 is pressed and the highlighted display portion is corrected by the designer, the corrected shape may not be realized (manufactured) by the processing method stored in the processing method input table 17. is there. In this case, it is necessary to register a new processing method in the processing method input table 17.

FIG. 11 is a diagram illustrating a screen example of the terminal when a new processing method is registered in the processing method input table.
When the highlighted display portion of the product 51a is corrected by the designer and the shape of the corrected portion cannot be realized unless it is a new processing method, a screen 55 is displayed on the monitor of the terminals 31 to 33 as shown in the figure. Is displayed. On the screen 55, buttons 55a and 55b are displayed. When the button 55a is pressed by the designer, a new machining method capable of realizing the corrected shape is registered in the machining method input table 17. When the button 55 b is pressed by the designer, a new machining method is not registered in the machining method input table 17.

The contents of FIG. 11 will be described with reference to a product modeling diagram.
FIG. 12 is a diagram illustrating a screen example of a terminal that displays a highlighted product.
A screen 56 shown in the figure shows an example of a screen displayed on the monitors of the terminals 31 to 33. Assume that the designer models the product 56a as shown on the screen 56. Assume that the product 56a is highlighted as shown in the figure.

FIG. 13 is a diagram illustrating a screen example of a terminal displaying a similar shape of a product.
A screen 57 shown in the figure shows an example of a screen displayed on the monitors of the terminals 31 to 33. It is assumed that shapes 57a and 57b similar to the product 56a are displayed on the screen 57 in response to a designer's request. It is assumed that the shapes 57a and 57b are, for example, ball lathes registered in the machining method input table 17 and the four corners of the opening are corrected. The shape 57a is formed by R relief at four corners of the opening, and the shape 57a is formed by relief of four corners of the opening.

When the shape 57a, 57b does not match the shape of the product to be designed, the designer directly corrects the shape.
FIG. 14 is a diagram illustrating a screen example of a terminal that displays products directly modified by the designer.

  A screen 58 shown in the figure is an example of a screen displayed on the monitors of the terminals 31 to 33. The screen 58 displays a product 58a directly corrected by the designer himself when the shapes 57a and 57b satisfying the designer's request are not displayed in FIG. When the shape corrected by the designer is realized by a new machining method that is not registered in the machining method input table 17, the modeling check unit 13 displays a screen as shown in FIG.

  For example, the product 58a escapes four corners of the opening. It is assumed that the corner relief is processed by “punch” that is not registered in the processing method input table 17, for example. In this case, according to an input from the designer, a “punch” machining method is stored in the machining method input table 17.

  When the modeling is completed, the processing condition check unit 15 selects a manufacturer who can request processing of the product with reference to the manufacturing request destination database 20. When a manufacturer that can request processing is not registered in the manufacturing request destination database 20, a screen asking whether to select from a manufacturer that cannot originally request processing is displayed on the monitors of the terminals 31 to 33.

FIG. 15 is a diagram illustrating a screen example of a terminal inquiring selection from a manufacturer that cannot make a processing request.
As shown in the figure, a screen 59 is displayed on the monitors of the terminals 31 to 33. On the screen 59, buttons 59a and 59b are displayed. When the button 59a is pressed by the designer, a manufacturer that can perform processing is selected from manufacturers that cannot originally request processing. When the button 59b is pressed by the designer, it returns to modeling correction. The designer will modify the product so that the product can be processed by a manufacturer who can request processing.

FIG. 16 is a diagram illustrating a screen example of the terminal when the button of FIG. 15 is pressed.
A screen 60a of FIG. 15A shows an example of a screen when a manufacturer that can be processed is selected from a manufacturer that cannot originally request a processing when the button 59a of FIG. 15 is pressed. A screen 60b of FIG. 15B shows an example of a screen when the manufacturer that cannot originally perform the processing request is not selected from the manufacturer that cannot perform the processing request when the button 59a of FIG. 15 is pressed.

Next, operation | movement of the server 10 of FIG. 4 is demonstrated using a flowchart.
FIG. 17 is a flowchart showing the operation of the server.
The server 10 executes processing according to the following steps.

  In step S <b> 1, the display unit 14 displays the processing method of the processing method database 16 on the monitors of the terminals 31 to 33. Thus, the designer can select a processing method of the product, for example, by lathe processing or by sheet metal processing.

  In step S <b> 2, the input unit 11 receives a processing method selected by the designer and a specific value related to a product shape when a product is manufactured by the processing method. At this time, the order of processing methods for processing the product can also be specified. The input unit 11 stores the accepted processing method and specific value in the processing method input table 17.

  In step S <b> 3, the modeling unit 12 models a product according to the operation of the designer's terminals 31 to 33. The display unit 14 displays the modeling shape on the monitors of the terminals 31 to 33. When one operation of modeling is performed by the designer, the modeling unit 12 proceeds to step S4.

In step S4, the modeling check unit 13 determines whether or not the shape of the modeling performed by the designer satisfies the various conditions set in step S2.
In step S5, if the check in step S4 does not satisfy the various conditions, the modeling check unit 13 proceeds to step S6. If the various conditions are satisfied, the process proceeds to step S10.

  In step S <b> 6, the modeling check unit 13 displays an edge or a face where the various conditions are not satisfied, that is, where the shape intended by the designer cannot be realized by the processing method and the specific value specified by the designer. The highlight display is performed on the terminals 31 to 33 via the unit 14. For example, it is highlighted as shown in FIG.

  In step S <b> 7, the modeling check unit 13 determines whether or not the designer has requested a new product correction by the designer. For example, a screen as shown in FIG. 8 is displayed on the monitors of the terminals 31 to 33, and a request for new correction from the designer is accepted. If there is no request for new correction, the process proceeds to step S8. If there is a request for new correction, the process proceeds to step S9.

  In step S <b> 8, the modeling check unit 13 acquires a processable shape similar to the shape of the product being modeled from the corrected shape database 19. The modeling check unit 13 displays the acquired similar shape on the monitors of the terminals 31 to 33 via the display unit 14. For example, as shown in FIG. 9, a processable shape similar to FIG. 7 is displayed.

  In step S9, the modeling check unit 13 directly accepts a modeling correction from the designer in response to the designer's request. The modeling check unit 13 stores the corrected shape in the corrected shape database 19. However, at this time, the modeling check unit 13 determines whether or not the shape corrected by the designer can only be realized by a new processing method. If the corrected shape cannot be realized unless it is a new processing method, the designer is warned to that effect, and the registration of the corrected shape is accepted from the designer and registered. For example, a screen as shown in FIG. 11 is displayed on the monitors of the terminals 31 to 33 to prompt the designer to change the processing method. Then, it accepts from the designer whether or not to register a correction by a new processing method. When correction by a new processing method is accepted, the processing method is stored in the processing method input table 17.

  In step S10, the modeling unit 12 determines whether or not the modeling has been completed. If modeling has not ended, the process proceeds to step S3. If the modeling is finished, the process proceeds to step S11.

In step S <b> 11, the processing condition check unit 15 selects a manufacturer that processes the modeled product with reference to the manufacturing request destination database 20.
In step S <b> 12, the processing condition check unit 15 determines whether or not the product modeled by the selected manufacturer can be processed with reference to the manufacturer processing database 18. If it is determined that processing is possible, the process ends. If it is determined that the processing is impossible, the process proceeds to step S13.

  In step S <b> 13, the processing condition check unit 15 displays a message indicating that there is no manufacturer that can process the product in the manufacturing request destination database 20 on the monitors of the terminals 31 to 33 via the display unit 14. For example, a screen as shown in FIG. 15 is displayed on the monitors of the terminals 31 to 33.

  In step S <b> 14, the processing condition check unit 15 refers to the manufacturer database 21 and searches for other manufacturers that can be processed. If a manufacturer that can be processed is registered in the manufacturer database 21, the process ends. If no manufacturer that can be processed is registered in the manufacturer database 21, the process proceeds to step S3. The designer remodels so that the manufacturer registered in the manufacturing request destination database 20 and the manufacturer database 21 can perform processing.

  The designer can specify a plurality of processing methods in step S1. In this case, by storing the processing methods and specific values in the processing method input table 17 in the order of the processing methods for processing the products, it is possible to deal with products processed by a combination of several types of processing methods.

  As described above, when one modeling operation is performed, it is determined whether or not the shape modeled with the specified processing method and the specific value can be processed. Then, the determination result is displayed on the designer's terminal. Therefore, reworking of the design process can be prevented, design work can be made more efficient, and costs can be reduced.

In addition, by highlighting the unworkable part of the product, the designer can immediately know the unworkable part.
Even when machining is impossible, by displaying a shape similar to the shape on the terminals 31 to 33, the designer can perform smooth work and the designer's modeling work can be reduced.

  Further, when the designer corrects the modeling when the machining is impossible, the corrected shape is stored in the corrected shape database 19 so that it can be utilized as design know-how, and can be used at the designer's individual level. It becomes possible to design without depending on.

Further, by referring to the manufacturing request destination database 20 after the modeling is completed, it is possible to reduce the time and effort of selecting a manufacturer who is scheduled to be processed by the designer.
