Description

  The present invention is a system for checking in advance whether or not a processing machine (CAM) for processing wood using the generated CAD data can execute processing according to CAD data in an apparatus for generating CAD data for precut processing. It is about.

  Conventionally, various proposals have been made on a system for creating CAD / CAM data for manufacturing a structural material of a wooden house by precut processing (Patent Documents 1 to 7 and the like).

  Patent document 1 provides “a processing device for building structure members that can perform integrated processing from structural design of buildings to reexamination of design, and further processing of building structural members using CAD data created in a design CAD device. A system that processes a structural material and the like by a CAM device when it is determined that the estimation table and the intensity distribution map are created based on the data designed and created by the CAD program, and after confirming these, ] Has been proposed.

  Patent Document 2 states that “the load applied to the horizontal member by inputting the shape data of the building in order to display so that it can be immediately understood whether there is a problem in the component material and which is the problem. Proposed a system that calculates the degree of stress from the structural calculation, displays the horizontal material with a bending stress level greater than the specified value in red, and displays the horizontal material with a shear stress level higher than the specified value in purple. ing.

  Patent document 3 states, “In order to present a compelling structural strength calculation result to the customer, the necessary data is extracted from the CAD data for precutting the structural material, and the wall strength, eccentricity, beam A system that outputs check results for each of the structure, column strength, and joints is proposed.

  Patent Document 4 states that, “In order to automatically determine whether or not the processing portion formed on the precut wood is formed according to preset processing data, the photographing means is moved along the longitudinal direction of the precut wood. , A system that compares the processed data with the image data of the processed portion and determines whether or not the processed portion is formed according to the processed data based on the comparison result is proposed.

  Patent Document 5 states, “In order to minimize the cost of residual material when pre-cutting, a short list of timber necessary for construction is generated from a structural plan generated from CAD data, and each piece of timber described in the short list is generated. Using the short data and the dimensions, quantity, and cost of the material of the standard materials available from the database as parameters, all combinations of pre-cuts of short wood on the short list are generated, and from these, predetermined end materials We propose a system that generates a two-dimensional array excluding combinations that are longer than the length, extracts the combination with the smallest end material from the two-dimensional array, and performs pre-cut production based on the extraction result.

JP 2000-76323 A JP 2001-207522 A JP 2001-303657 A JP 2000-71148 A JP2008-47002 JP-A-9-109108 JP2007-149062

Here, in the pre-cut factory, work is performed according to the following flow.
(1) The sales team receives an order after having a meeting with a construction company and a customer (hereinafter referred to as the client).
(2) Enter a draft with CAD according to the contents of the meeting.
(3) Submit the draft to the client and obtain approval from the client.
(4) The client submits an application to confirm the building with the draft as a part of the document.
(5) Processing using a processing machine (CAM) using data created by CAD.

  However, CAM cannot process all data created by CAD, and depending on the value of the processed data, it may not be processed or only a part may be processed. In such a case, there are “(a) a handling method by which an operator manually performs machining for which CAM has not been performed” and “(b) a handling method for changing how to assemble the draft so that machining can be performed”.

  In some cases, the handling method of (a) can be easily performed. For example, the work of cutting a lumber joint into a round shape is difficult to cut with a chisel but cannot be manually processed. If you notice that there is a process that cannot be processed by hand, you can use the corresponding method in (b). However, if you notice it after processing, naturally, you will not be able to use the material, so a new material will be pre-cut. You must prepare at your own expense. In this case, since the way of assembling is changed, the peripheral members may have to be reworked.

  Conventionally, in the handling method of (b), even after the confirmation application of (4) is passed, there is no problem if a change application is submitted, and the cost of re-application is also small. However, recently, the examination standards have become stricter, and changes to the confirmation application are only allowed to be minor, practically only corrections for typographical errors and omissions. In this case, the application fee is borne by the pre-cut factory, and the delivery date may not be met.

  Therefore, in order to adopt the handling method of (b), it is necessary to know that “CAM cannot be processed” at the stage of (2) before obtaining approval.

  On the other hand, the conventional technology cannot sufficiently cope with such a problem.

  In view of the above, an object of the present invention is to make it possible to accurately check the processing by CAM at the stage of creating CAD data.

  Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the precut processing data creation support apparatus 1 of the present embodiment includes a personal computer 3 including a hard disk 2 in which a CAD / CAM data creation program is installed, a display 4, a keyboard 5, and a mouse 6. A CD-ROM drive 7, an FD drive 8, and a printer 9. The hard disk 2 is installed with a CAD / CAM data creation program and various information necessary for executing this program.

  The hard disk 2 includes CAD / CAM disclosed as an embodiment of JP-A-2005-165906, JP-A-2005-165907, JP-A-2005-165908, JP-A-2005-165909, JP-A-2005-165918, and JP-A-2007-149062. A data creation program and various information for executing the program are installed.

  By executing this CAD / CAM data creation program, the floor plan is determined on the display 4 as shown in FIG. 2, and the layout of horizontal members and pillars at each level is shown as shown in FIG. You can create a sketch.

  In the present embodiment, a joint metal database for the hardware method is also installed in the hard disk 2. In this fitting hardware database, the type and model number of the fitting hardware and data relating to the shape and dimensions thereof are stored. After determining the arrangement of the horizontal member and the column member, the designer determines the type and model number of the joint hardware between the structural members, and inputs them as joint / joint data.

  Thereby, the arrangement of the structural material and the fitting hardware are determined by the CAD function, and the result is stored in the storage area of the hard disk 2 as CAD data.

  This CAD data consists of the name of the structural material constituting the house, the type of structural material, the three-dimensional position coordinates at both ends, the type of processing at the end, the type of fitting hardware, the model number, and the three-dimensional position coordinates. Remembered.

  After designing using the CAD function as described above, as shown in FIG. 4, when specifying the hierarchy to be checked and displaying the sketch, and specifying the center point of the location to be checked, the clipping box 10 is displayed. appear. In the present embodiment, a cube having a predetermined size centered on a point designated by the operator is employed as the cutout box 10. Note that the dimensions of the cube can be arbitrarily changed from the default values.

  Thereafter, the three-dimensional display engine provided in the CAD program is operated, and as shown in FIG. 5, the structural material included in the cutout box 10 is displayed as a three-dimensional image, and the structure outside the cutout box 10 is displayed. The material is displayed as a planar image on the hierarchical level. However, this planar image also simply ignores the volume in the height direction in the present embodiment, and the data itself is based on three-dimensional coordinate data.

  FIG. 5 shows a state in which the image has already been rotated. For the structural material of the portion included in the cutout box 10 in the designated hierarchy, a solid tertiary having the outermost surface of the cutout box 10 as a cut surface. The original image is displayed, and the other parts are displayed as a planar image in which the position coordinates after rotation are determined based on the position coordinates of the height of the hierarchical surface.

  Then, when enlargement is instructed by the function of the three-dimensional display engine, the range of the cutout box 10 can be enlarged and confirmed as shown in FIG. As shown in the drawing, the joint hardware 21 and 22 existing within the range of the cutout box 10 is displayed as an image of a three-dimensional shape at the attachment position to the structural material. At this time, as shown in the figure, only the portion of the hardware 22 provided on the end of the wooden shell that protrudes from the cut surface of the structural material is displayed. As hardware data, there is information on the entire shape, but the part embedded in the structural material is hidden by displaying the solid model of the structural material on the front. Further, although the portion displayed in FIG. 6 is originally located outside the cutout box 10, the hardware 22 is displayed without being cut at the outermost surface of the cutout box 10 like a structural material.

  In addition, the shape of the joint and joint by the conventional shaft assembly method can be displayed as in FIG. In this display, the shape / dimension data of the joint / joint is installed in the hard disk 2 in the same manner as the hardware data.

  Further, as shown in FIG. 1, the hard disk 2 of the precut processing data creation support device 1 of the present embodiment has a CAD data storage area 2a for storing CAD data created by this device for each property, and a book CAM processing data storage area 2b for storing, for each property, CAM processing data created from CAD data using the function of the device, and an operation check corresponding to the processing line installed in the precut factory A CAM information storage area 2c for storing the program and a check result storage area 2d for storing the result of the operation check are secured.

  In the CAM information storage area 2c, a conversion program for converting machining data for CAM into operation code data of a machining axis used in the machining machine, and an operation code converted by the conversion program are stored in the CAM information storage area 2c. A determination program for determining whether or not machining according to the data can be executed in comparison with the movement limit of the corresponding machining axis in the processing machine is stored.

  The CAM information storage area 2c is configured to store the conversion program and determination program for each processing line for a plurality of precut processing lines. Furthermore, these programs stored in the CAM information storage area 2c are stored so that they can be read out by designating line names. In addition, the CAM information storage area 2c is configured such that the program of the designated line can be rewritten by designating the line name and inputting the program. As a result, a judgment program corresponding to the line configuration for each precut factory is stored, and when there is a change or addition of functions or operations due to changes in the specifications of the processing machine, etc. Etc. can be updated to the latest information.

  In the check result storage area 2d, the operation check determination result is stored as information for each member for each property. In addition, in the information for each member, the processing part (joint / joint) of the member and the check result are associated with each other.

  The precut machining data creation support device 1 of this embodiment checks whether the CAD / CAM data created by using this device can actually be machined in the precut machining facility (CAM). Therefore, a program that executes the following processing is also installed.

[Machining check program (Fig. 7, Fig. 8)]
This program can be executed when the “CAM-processed data” output from the CAD is provided as a property list. Here, the processing data for CAM is not the same as the CAD data, but is data obtained by converting the content of the CAD data for CAM. In actual processing, this data is passed to the processing machine (CAM) via a flexible disk, MO, USB flash memory, and LAN.

  Further, the processing data for CAM is input by selecting from the property list. This “Property List” is a list of properties to be processed and properties that have been processed.

  When the processing check program is activated, a list of properties is first displayed (S11). The property list is displayed as shown in FIG. When the “read property” button is pressed on this screen (S12: YES), a screen as to which of the properties to select is displayed as shown in FIG. 9B (S13). For example, when the top property is selected and the “Read” button is pressed (S14: YES), the processing data for the CAM of the property is input (S15), and the CAM operation check program is started (S16). In the activated CAM check program, as shown in FIG. 8, "CAM machining data" is converted into operation codes for each machining axis (S21). Then, after conversion into each operation code, it is checked whether or not the movement can be made by comparing with the movement limit of each axis, and it is determined whether or not it corresponds to “machining warning” or “machining impossible” (S22). Then, the determination result is stored in the check result storage area 2d (S23), and the check completion is output (S24).

  Here, “processing warning” means that it is determined that only a part of the processing can be executed, and “processing impossible” means that it is determined that the processing cannot be performed at all.

  When the processing of the CAM operation check routine is completed and check completion is output (S17: YES), the next step in the machining check routine is executed, and the warning information is developed in the memory (S30), and the warning information Is added to the property list as data, and the “Property Management Screen (FIG. 10A)” is displayed (S31). When the user presses the “parts list” button on this property management screen (S32: YES), a “parts list screen (FIG. 10B)” is displayed (S33). At this time, the parts with “processing warning” and “processing impossible” are displayed in yellow-green on the screen.

  When a part is selected by placing the cursor on the part on the list screen and double-clicking (S34: YES), the processing information for that part is displayed (S35). At this time, the processing for which a warning has been issued is displayed in a different color (yellow) from the others (FIG. 11A). When machining is selected on this display screen (S36: YES), the content (machining warning (or machining impossible)) is displayed in the “Warning presence / absence” area of the screen (S37).

  Further, when the “warning information” button at the bottom of the screen of FIG. 11A is pressed (S38: YES), information indicating why the process could not be processed is displayed (S39). A display example is shown in FIG.

  As described above, the machining check program can inform the worker of warning information of parts. This machining check program is provided as a program for performing an operation check using a monitor on the machining line side, and this program is stored in the CAM information storage area 2c.

[Program that displays warning information only on CAD]
By executing the above program, the following operations are executed in batch.
(1) Output “processing data for CAM” from CAD,
(2) Read the data into the “Machining Check Program”
(3) Display which machining has a problem on the CAD screen based on the warning information (the warning information includes information for specifying the member and the machining).

  Since the warning information is expanded on the memory in step S38, it is saved as a text file on the CAD side on the disk.

The table below explains a part of this text. Information necessary for specifying the data on the CAD side is included.

[Program behavior in batch processing (FIG. 12)]
First, the CAD input screen is opened (S101). As shown in FIG. 13A, this CAD input screen displays a sketch and various buttons. By designating a property, this processing is executed by a map display program that reads out CAD data of the property from the CAD data storage area 2a and displays it as a map.

  When “execution of machining check” is instructed on this CAD input screen (S102: YES), a processing machine selection screen is displayed (S103). As shown in FIG. 13B, this selection screen is displayed when there are a plurality of horizontal material processing machine lines in the pre-cut factory. Therefore, the operator selects which of the plurality of lines the data is to flow through on the processing line selection screen. The step of performing this process corresponds to a check command program.

  When the machining line is selected and the “machining check” button is pressed (S104: YES), the program described with reference to FIGS. 7 and 8 is read from the CAM information storage area 2c for the selected machining line (S105). ), The processing data for CAM of the property displayed as the floor plan is read from the processing data storage area 2b for CAM (S106). The machining data for CAM is data converted from CAD data into a form for passing to a machining machine (CAM) via a flexible disk, MO, USB flash memory, or LAN, and before the machining check is executed. It is generated using a machining data output program and stored in the CAD machining data storage area 2b for each property.

  Thereafter, the processing of S21 to S24 is executed in the computer (S107), and when the check completion is received (S108: YES), a warning information window for the entire property is displayed over the CAD input screen (S109). As shown in FIG. 14A, the content of the warning information window is an error list that can read which machining of which member is “machining warning” or “machining impossible”.

  In this error list, when a line whose error content is to be confirmed is selected and double-clicked (S110), the problem component is highlighted on the sketch (S111). As shown in FIG. 14 (B), the member selected in this error list is highlighted in red on the plan view (portion surrounded by an ellipse), and in the lower portion of the screen, A figure showing what kind of processing is also displayed (S112). Also on this screen, the processing in question is highlighted and displayed in red (S113, a portion surrounded by a circle in FIG. 14B).

  In the present embodiment, the CAD function is used to associate the drawing and the member, and the member and the processing, so the row in the error list is associated with the member in the drawing, and the member in the drawing. Since the shape of the process can be specified if is specified, display as shown in FIG. 14B is possible. Also, the sketch and the error list are displayed partially overlapping on the screen, and when the member is specified, the error list is moved so that the specified member is not hidden in the error list, and the member diagram is displayed below. This makes it possible to grasp the problem location and the content of the problem at a glance.

  As described above, it is possible to obtain information as if it was read by the CAM while operating the CAD.

[Avoid errors]
Then, actually change the sketch. The slanted joints in question are stored as shown in FIG. Therefore, the direction of the slanted joint is changed by changing the extension of the horizontal member. As a result of this change, the horizontal horizontal member was initially a male material, but it becomes a female material by extending the end. Then, the joint that is applied from the lower right of the joint is stored as shown in FIG.

  At this time, when the screen of FIG. 15A is displayed, a message such as “Please recreate the joint with another female material by changing the way of assembling” can also be displayed. In order to achieve such a function, several pattern messages are prepared, and one of these pattern messages is selected and displayed based on the information on the relationship in the sketch, or these A program may be incorporated so as to realize a method for displaying a message that does not clearly correspond to the relationship among the pattern messages.

  As described above, the CAD input person can remove the warning information of the CAM in advance.

  In this embodiment, since the check is performed using the same program as the CAM of the processing machine that actually performs the processing, the CAD side only needs to develop a program for exchanging data with the CAM program. It is done.

  Although the specifications of CAM differ depending on the user, since checking is performed using the CAM program delivered to each user, it is not necessary to develop a program individually.

  The user can quickly confirm the warning on the processing machine side at the stage of inputting the CAD, and can quickly show the change of the plan and the change of the plan to the customer. In addition, since it is possible to know in advance that processing cannot be performed by the CAM, it is possible to issue a manual processing instruction to the factory side without excess or deficiency. As a result, it is considered that the number of complaints is reduced because it is possible to prevent omission of manual processing.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the scope of the invention.
