  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

<First Embodiment>
First, an example of the configuration of the information processing system in the first embodiment of the present invention will be described with reference to FIG.

  The information processing system of the present invention is configured such that a PC 100 and a server 200 are communicably connected via a LAN 101 (local area network). The server 200 stores three-dimensional model data (an assembly file, a part file, etc.) generated by CAD software (CAD software). For example, data such as 801 and 802 in FIG. 8 is stored.

  The three-dimensional model composed of 801 and 802 shown in 800 of FIG. 8 is a result generated by pouring and hardening the resin into the groove portion of 803 in the state where 801 and 803 are in contact with each other in 810 of FIG. Indicates the shape of the object.

  It is assumed that the PC 100 is installed with CAD software and an overlap determination tool for determining the overlap of components based on information acquired from the CAD software. When the 3D model is viewed from the top, the overlap judgment tool overlaps the hole on the model (third-order model (part)) on the top surface (front surface) and the model on the bottom surface (back side for the top surface). And determine the overlapping position. Then, the position determined to be overlapped is determined as a punching location for punching the back part through the hole. In other words, it is determined to launch the rear part.

  Thus, for example, a part 802 is punched through a hole in the plate 801 as shown by 1101 in 1100 of FIG. 11, and an unnecessary part 802 is peeled from the part 801 as shown in 1110 of FIG. 11. As a result, a new part (punching model / 1102 and 1103 in FIG. 11) can be easily created to leave only 1106 and 801 connected to 802 as necessary parts.

  In other words, for example, the PC 100 designs the punching part to be used in a part punching device that moves the punching model (punching part) like a press machine and peels off the unnecessary part like a press machine. It is a device to do. The above is the description of FIG.

  Hereinafter, an example of the hardware configuration of various apparatuses according to the first embodiment of the present invention will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 202 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs to be described later are stored.

  A RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for execution of processing from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

  An input controller 205 controls input from a keyboard (KB) 209 or a pointing device such as a mouse (not shown). A video controller 206 controls display on a display device such as a CRT display (CRT 210). In FIG. 2, although described as CRT 210, the display device is not limited to the CRT, but may be another display device such as a liquid crystal display. These are used by the administrator as needed.

  A memory controller 207 is connected to the hard disk (HD), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, etc. via an adapter. The access to the external memory 211 such as a compact flash (registered trademark) memory is controlled.

  A communication I / F controller 208 is connected to and communicates with an external device via a network (for example, the LAN 101 shown in FIG. 1), and executes communication control processing on the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 enables display on the CRT 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the CRT 210.

  Various programs to be described later for realizing the present invention are recorded in the external memory 211 and executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, definition files and various information tables used when executing the program are also stored in the external memory 211, and a detailed description thereof will be described later. The above is the description of FIG.

  Next, an example of a functional configuration of the functional configuration according to the first embodiment of the present invention will be described with reference to FIG.

  The three-dimensional model storage unit 331 is a storage unit that stores a three-dimensional model. For example, the three-dimensional model name (file name), reference relationship, the position (X, Y, Z) and direction (X of the three-dimensional model in the three-dimensional space with X, Y, Z = 0, 0, 0 as the origin. , Y, Z), and shape data are stored as three-dimensional model data. X, Y, and Z are axes in the vertical, horizontal, and height directions in a three-dimensional space, respectively.

  The 3D model generation unit 311 is a generation unit that generates a 3D model in response to a user operation received by the 3D model generation unit instruction reception unit 312 or an instruction from a tool such as an overlap determination tool. The three-dimensional model storage control unit 313 is a control unit that stores the generated three-dimensional model in the storage unit. For example, the server 200 is instructed to transmit 3D model data and store it in the 3D model storage unit 331. The three-dimensional model display unit 314 is a display unit that displays the generated three-dimensional model on a display screen.

  The object storage unit 321 stores and manages the outline (a set of lines forming the outline) of the three-dimensional model acquired from the CAD software as an object. The contour line is a line indicating the contour of the three-dimensional model when the three-dimensional model is projected from a certain direction. The two-dimensional surface for projecting the contour is a projection plane, and the two-dimensional diagram for projecting the contour line is projected. Let's say. For example, a front view, a right side view, a left side view, a top view, and the like are projection views. The overlap determination unit 322 is a determination unit that determines whether a plurality of objects overlap. For example, in the top view of the three-dimensional model, it is determined whether there is a hole in the model on the upper surface (front surface) that overlaps the model on the lower surface (back surface for the upper surface) side.

  That is, it is a determination unit that determines whether there is another part that can be punched beyond the hole opened from the front surface.

  The punching target specifying unit 323 is a place where the hole (position of the hole) determined to be overlapped by the overlap determination unit is inserted, for example, from the upper direction to the lower direction, and the part on the back side is punched out. Specify (determine) and store.

  The identification display unit 324 is a display unit that identifies and displays the place determined to be overlapped by the overlap determination unit 322. For example, the hole on the front side (front side) model that overlaps with another model on the back side is identified as a hole to be punched, and the color is changed for identification display. Holes that do not have another model on the back are not identified as punching targets and are not identified.

  The punching model shape determining unit 325 is a determining unit that determines the shape of a three-dimensional model that punches a portion to be punched. The punching model generation instruction unit 326 is an instruction unit that instructs the CAD software to generate the three-dimensional model determined by the punching model shape determination unit 325.

  The position determination unit 327 is a determination unit that determines the position of the three-dimensional model on a member that serves as a foundation on which the three-dimensional model is to be placed, which is a position where a three-dimensional model that punches a portion to be punched is placed. The punching model generation instruction unit 326 instructs the CAD software to place the three-dimensional model at the position determined by the position determination unit 327. The above is the description of FIG.

  Next, an overview of processing in the first embodiment of the present invention will be described with reference to FIG.

  Hereinafter, the processing shown in each step of FIGS. 4 to 6 is executed by the CPU 201 of the PC 100 using the function of the CAD software or overlap determination tool installed in the PC 100.

  The CAD file (three-dimensional model) designated by the user operation is expanded and the information of the CAD file is displayed on the display screen. For example, an assembly file selection / development operation is accepted, and a screen such as 1600 in FIG. 16 is displayed. In 1600, the assembly 1 is deployed. Each assembly file holds reference relationship information. The reference relationship information includes information indicating which assembly or part is referenced by the assembly file that holds the reference relationship, and X, Y, and Z coordinates in the three-dimensional space of the referenced assembly or part. That is, the positional relationship between parts in a three-dimensional space (depth direction) is stored. For example, the height direction is a depth direction for a surface extending in the vertical direction and the horizontal direction.

  Reference numeral 1601 denotes a display unit that displays a tree indicating a reference relationship between data of other assembly files and parts referenced by the assembly file. Reference numeral 1603 denotes a display unit that reads out component data in which a component shape is stored in accordance with the reference relationship information of the assembly being developed, and arranges and displays the data in a three-dimensional space. Reference numeral 1602 denotes an activation button of the overlap determination tool.

  The CAD software accepts an operation (start-up instruction) for pressing the start button of the overlap determination tool by a user operation, and starts the overlap determination tool accordingly (step S401). The overlap determination tool activated by an instruction from the CAD software (step S402) displays the main dialog 1610 (step S403), and accepts the selection of the radio button 1612 displayed on the main dialog 1610. An operation of pressing the “contour request” button 1613 is accepted. In response to the operation, the overlap determination tool uses a CAD software API (Application Programming Interface) to make an acquisition request for the outline of the file (three-dimensional model) opened by the CAD software (step S404).

  The pressing of the “contour request” button 1613 is an instruction to execute a process for confirming the designation of the target part and the existence of another part that can be launched through the hole of the designated part.

  Specifically, the CAD software is requested and obtained from a list of model surfaces being developed by the CAD software, and an arbitrary condition (specifically, an upper surface in the Z-axis direction, etc.) is obtained from the list of surfaces. Get matching faces. Among the contour lines of the surface, the contour line of a predetermined model (file name component registered in the overlap determination tool in advance) and the contour of another model on the back side of the predetermined model (outline) ). For example, the character string “front” is included in the file name of the model located on the front side (eg, the upper surface side in the height direction) of the predetermined model X, and the character string “back” is included in the file name of the model located on the back side. A model is generated and stored so that is included. Then, it is assumed that the overlap determination tool requests the CAD software for the contour line of the part with model name = X and the contour line of the model whose file name includes the character string “back”.

  More specifically, the model being developed here is an assembly file that refers to a three-dimensional model of a plurality of parts, and the overlap determination tool receives the press of the “contour request” button 1613, and The CAD software is instructed to specify the surfaces (for example, upper surfaces) of a plurality of parts referred to by the assembly.

  In other words, the direction of the Z-axis that goes straight from top to bottom in the three-dimensional space is specified, and the front (upper surface) of the component in the Z-axis direction is specified.

  Also, the CAD software is requested for the upper surface of a predetermined component (eg, model X) and the contour line of the upper surface of the component on the back side of the component among these surfaces. That is, the height direction which is a direction orthogonal to the upper surface is specified (corresponding to the direction specifying means), and the contour line of the component on the back side (back side) of the component in the direction is requested. It is assumed that the file name of the predetermined model is stored in advance in the external memory of the PC 100.

  When the “contour request” button 1613 is pressed, an assembly file being developed by the CAD software is designated, a predetermined part among the parts referred to by the assembly file is designated by the designation, and the designated part is passed through the hole of the designated part. This is a process execution operation for confirming the existence of another part that can be launched.

  The CAD software receives the instruction and request (step S405), and in response to the request, in the file being developed when the 3D model is viewed from above (from the direction of plus to minus in the Z-axis direction). The outline of the model X and the outline of the part on the back side of the model X are generated and returned to the overlap determination tool (step S406). For example, a set of contour X and Y coordinates (vertex position of each contour line in a plane intersecting the Z-axis direction) as shown in the top view of the three-dimensional model is generated and returned. An example of the contour of the top view is shown in FIG. 900 of FIG. 9 shows the outline of the three-dimensional model shown by 800 of FIG.

  An example of the contour information of the component on the back side of the component X in the coordinate information of the contour line generated and returned to the overlap determination tool is shown in the back object information 720 of FIG. At this point, the object name is empty.

  The overlap determination tool receives and acquires information about the predetermined model (part X) and the outline of each part on the back side from CAD software, and exists on the predetermined model among the outlines of the predetermined model The outline (hole object) of the hole to be extracted is extracted, inserted into the object information 710, and stored in the external memory (step S407). That is, information on the position of a hole opened from the upper surface of a predetermined model is specified and stored. Further, the outline of the model on the back side of the predetermined model is extracted, and information on the outline indicating the outline is inserted into 720 in FIG. 7 and stored in the external memory.

  The object information 710 in FIG. 7 is information indicating the outline of an object (object name 712) formed by connecting lines (line names 713) in the three-dimensional model 711 (parts). The line type 714 indicates the line segment attribute of each line (line name 713).

  The overlap determination tool assigns an object name to the acquired object, and arranges the line type (line segment, specifically, the edge on the model) by assigning a line type of straight line, arc, or perfect circle to the object. (The line type included in the attribute of each contour line acquired from the CAD software is written in the object information 710), and other line segments such as splines are replaced with straight lines connecting the start and end points and stored in the object information 710. Line indicates a straight line, arc indicates an arc, and circle indicates a perfect circle. Each line holds a start point, an end point 715, a radius 716, a central coordinate 717, and a start angle / rotation angle 718, respectively, as necessary. Which line type line holds the value in which item is as shown in 710, for example. It is assumed that the object information 710 stores the contour line information of the predetermined model whose file name is specified by the overlap determination tool in step S404, and stores the contour line of the hole on the model. For example, information on the outline of the hole on 801 in FIG. 8 is shown.

  The back object information 720 indicates the outline information of the outline of the 3D model on the back side of the object indicated by the object information 710. For example, the outline information of the part 802 in FIG. Since the value of each item is as described above in the description of 710, the description is omitted.

  The overlap determination tool reads the object information (contour line information / 710 and 720 in FIG. 7) stored in step S407 into the memory (step S408 / obtains). Then, the process proceeds to step S409, and an overlap determination process is executed (step S409). Details of the processing in step S409 in the first embodiment will be described later with reference to FIG.

  Here, with reference to FIG. 5, the flow of the overlap determination process in the first embodiment of the present invention will be described.

  The overlap determination tool acquires one unprocessed hole object (a set of lines grouped by object name) in the object information 710 (step S501), and acquires one object of the back object information 720 (step S501). S502). Then, one unprocessed line segment is acquired from the line segments of the object (back object) acquired in step S502 (step S503), the counter indicated by 730 in FIG. 7 is initialized (step S504), and step The object name of the back object acquired in S502 (or step S516 described later) is the object name 731, the name of the line segment acquired in step S503 (or step S517 described later) is the line name 732, and step S501 (or described later). The object name acquired in step S518) is inserted into the count object name 733 and stored. The role of the counter 730 will be described later.

  The overlap determination tool generates a virtual straight line (virtual straight line 1001) tilted at an arbitrary angle of 1 degree or more in the horizontal direction as indicated by 1000 in FIG. 10, and is acquired in step S503 as shown in FIG. It arrange | positions to the starting point of the performed line segment (step S505).

  For example, it is assumed that the arbitrary angle (predetermined elevation angle) is 3 degrees. It is assumed that the predetermined elevation angle value is stored in the external memory of the PC 100 and can be arbitrarily changed by a user operation via a setting screen (not shown). Then, one unprocessed line segment is acquired from the line segments of the object acquired in step S501 (step S506).

  The overlap determination tool determines whether there is an intersection between the virtual straight line 1001 arranged in step S505 and the line segment constituting the acquired hole object (step S507). If there is an intersection, the number of intersections 734 of the counter 730 is set to 1. Count up (step S508), and the process proceeds to step S509. If there is no intersection, the process proceeds to step S509.

  The overlap determination tool determines whether the hole line segment (710 line segment) that has been determined whether there is an intersection in step S507 is the last of the unprocessed line segments that constitute the hole object acquired in step S501. (Step S509 / that is, it is determined whether all the hole line segments acquired in Step S501 have been processed). If an unprocessed line segment still remains, one unprocessed line segment is acquired from the hole object line segments acquired in step S501 (step S515), and the process proceeds to step S507.

  When all the line segments of the hole object acquired in step S501 have been processed, the overlap determination tool determines whether the value of the intersection number 734 of the counter 730 is odd or even (step S510). When the number of intersection points is an odd number, as shown in FIG. 10, the line segment of the back object being processed acquired in step S503 (or step S516 described later) is acquired in step S501 (or step S518 described later). Then, it is determined (determined) that the virtual straight line overlaps the intersecting hole object, and the process proceeds to step S514. Further, the hole object acquired in step S501 (or the hole object acquired in step S518 described later) is a hole at a position overlapping with the object on the back surface, and is specified as a place where the back model is punched, and stored in the external memory. Store (step S514). Specifically, as indicated by reference numeral 740 in FIG. 7, which model (part name 741) and which object (target part 742) indicates the location to be punched are stored.

  In other words, it is determined that there is a back side part that can be punched through the hole for the hole having an odd number of intersections 734 of the counter 730, and the back side part is determined to be driven through the hole. To do.

  When the number of intersection points is even or 0, as shown in FIG. 10, it is determined that the line segment of the back object being processed acquired in step S503 or the like (or step S516 described later) does not overlap with the hole object ( Determination), and the process proceeds to step S511.

  The overlap determination tool determines whether the line segment of the back object being processed is the last line segment of the unprocessed line segments that form the back object (step S5111 / that is, acquired in step S502 or S517 described later) It is determined whether or not all the line segments of the object on the back side of the predetermined part X have been processed). If there is an unprocessed line segment, one unprocessed line segment is acquired from the line segments of the background object being processed (step S516), and the process proceeds to step S504.

  If all the line segments constituting the back object being processed have been processed, the overlap determination tool determines whether all the back objects in the back object information 720 have been processed (step S512). If there is an unprocessed back object, one unprocessed back object is acquired (step S517), and the process proceeds to step S503. If all the back objects have been processed, the process proceeds to step S513.

  The overlap determination tool determines whether all hole objects in the object information 710 have been processed (step S513).

  That is, it is determined whether or not a hole that is open on the front surface of a predetermined part X specified by a user operation (eg, a hole that is open on the upper surface in the height direction) overlaps the rear object being processed. Judge whether there is a hole that is not. If there is an unprocessed hole object, an unprocessed hole object is acquired (step S518), and the process proceeds to step S502. If all the hole objects have been processed, the processing in FIG. 5 ends. The above is the description of FIG.

  Returning to the description of FIG. In step S410, the overlap determination tool reads out and acquires the determination result in step S409 (the punching target portion 740 in FIG. 7) from the memory, and identifies and displays the object indicated by the target portion 742 on the display screen (step S410).

  For example, the hole object stored in the punching target part 740 is selected, and the color of the hole object in the selected state is changed to a color (for example, red) indicating that it is in the selected state, and is displayed. An example of the state of identification display is shown at 1011 in 1010 of FIG. Thereafter, the process proceeds to step S411. Details of the processing in step S411 will be described later with reference to FIG.

  As described above, according to the present invention, it is possible to provide a mechanism that can easily identify a position where a hole of a part and another part overlap.

  For example, when another model exists beyond the hole of a predetermined model, the hole can be specified and stored as an object to be punched.

  That is, it is possible to provide a mechanism that can easily determine whether there is another part that can be punched through the hole of the part on the back side of the part.

  In addition, by identifying and displaying the identified hole to be punched on the display screen, the user can confirm the location to be punched.

  Next, a flow of new object generation / arrangement processing in the first embodiment of the present invention will be described with reference to FIG.

  The overlap determination tool CAD displays a list of three-dimensional models arranged on the same axis (in the same direction) as the hole of the punching target part 740 and facing the same direction (for example, from the top to the bottom) of the hole. A request is made to the software (step S601). The requested model list is arranged in front of the hole in the direction from the top to the bottom on the Z axis, for example, with respect to the three-dimensional model with a hole (for example, 801 in FIG. 8). It is a list of models that are arranged on the same axis as the hole and facing the same direction as the hole among the models (the name includes the front character string).

  More specifically, the overlap determination tool transmits a punching target portion 740 to CAD software, and generates a virtual line of the central axis of each hole included in the punching target portion 740 and interferes with the virtual line. A list of parts on the near side of the hole in the shaft is requested.

  When the CAD software accepts the request (step S602), it returns a model list corresponding to the request to the overlap determination tool (step S603).

  Specifically, in response to a request from the overlap determination tool, the CAD software generates a virtual line of the center axis of each hole included in the punching target portion 740 received from the overlap determination tool and interferes with the virtual line. In the part, list the file name of the part on the near side of the hole of the axis that interfered with each hole (the group of the line name of each looped line segment and the start point / end point position of each line segment). Generate and send it back to the overlap determination tool.

  The overlap determination tool receives this (step S604), and for all hole objects, determines whether the three-dimensional model having the shape corresponding to the hole is arranged on the same axis as the hole (step S605). That is, it is determined whether or not there is a component having a shape corresponding to the hole in the file name list of the component in front of each hole received from the CAD software.

  A three-dimensional model of a shape corresponding to a hole is a file name 3 corresponding to a combination of line types constituting a hole object, which is stored in an unillustrated association file stored in advance in the external memory of the PC 100. It is a dimensional model. For example, the line type = circle is associated with the file name of a three-dimensional model (for example, x01.prt) composed of one cylindrical model. Also, it is assumed that the combination of line type = line and arc is associated with the file name (assembly file name / example: x02.asm) of a three-dimensional model composed of two cylindrical models.

  The overlap determination tool ends the process when it is determined that the three-dimensional model having the shape corresponding to the hole is arranged on the same axis as the hole for all the hole objects. If it is determined that there is a hole in which the corresponding three-dimensional model is not arranged, a dialog as shown in FIG. 14 is displayed on the display screen (step S606).

  The overlap determination tool determines whether an operation for generating and arranging a three-dimensional model having a shape corresponding to a hole has been received (whether the “Yes” button has been pressed) has been received in the dialog 1400 (FIG. 14) (step S607). If the operation for generating / arranging the three-dimensional model having the shape corresponding to the hole is not received (when the “No” button is pressed), the process ends. If an operation for generating and arranging a three-dimensional model having a shape corresponding to the hole is received, the process proceeds to step S608.

  In step S608, the overlap determination tool acquires the shape of the target part 742 (hole object) in the punching target part 740 (step S608).

  Specifically, the overlap determination tool calculates the object name of the hole object in which the corresponding three-dimensional model of the shape is not arranged in the three-dimensional space, the object name stored in the object information 710, the line name, and the starting point of the line. -Specify using the position of the end point, the list received from the CAD software, and the information of the three-dimensional model of the shape corresponding to the hole stored in the external memory.

  That is, the hole object in which the corresponding three-dimensional model is not arranged in the three-dimensional space is specified in the punching target portion 740.

  Thereafter, the processes in steps S609 to S611 are repeatedly executed for the number of hole objects for which the corresponding three-dimensional model is not arranged in the three-dimensional space.

  The overlap determination tool acquires one unprocessed hole object among the hole objects in which the corresponding three-dimensional model acquired in step S608 is not arranged in the three-dimensional space.

  Then, for example, what type of line segment combination the hole object indicated by the acquired target portion 742 is identified by acquiring the line type constituting the object. Then, a file name model corresponding to the shape of the hole object is read from the external memory and acquired (step S609). That is, the shape of the punching part for punching the part through the hole is determined. It is assumed that the three-dimensional model file is stored in a predetermined storage area of the server 200 in advance.

  The overlap determination tool determines from the acquired hole diameter that a contour with a predetermined length of clearance is generated inside the hole, and the diameter of the model acquired in step S609 is determined as the generated contour diameter. To do. That is, the shape and size of a newly generated component are determined (corresponding to size determining means).

  The overlap determination tool notifies the CAD software of the file name of the three-dimensional model acquired in step S609, and instructs the CAD software to place the model of the file name at a predetermined position (step S611 / generation control means, Applicable to placement control means). The predetermined position here is, for example, a position stored in association with the three-dimensional model being processed (for example, 801 in FIGS. 8 and 11) (for example, the hole object acquired in step S608). In the case of circle), this is a point on the axis of the hole on the three-dimensional model indicated by the hole object, and is a position that is a predetermined distance away from the center point of the hole in the Z-axis direction. For example, the predetermined position for the hole 1104 in FIG. The center point of the hole is, for example, the position of the center of the hole on the same plane vector as the upper surface of the component 801. When the hole object acquired in step S608 includes arc (arc), a position that is a distance from the center point of arc by a predetermined distance in the Z-axis direction is set as the predetermined position (corresponding to position determining means). . The predetermined positions corresponding to the hole 1105 are a plurality of positions 1103 (a plurality of points). The overlap determination tool identifies the predetermined position and notifies the CAD software, and instructs the predetermined software to arrange the three-dimensional model acquired in step S609 with the diameter determined in step S610. .

  The CAD software accepts the instruction (step S612), and acquires, copies (generates) a three-dimensional model corresponding to the hole in accordance with the accepted instruction, changes the size, and performs a process of placing it at a predetermined position (step S612). S613). For example, a pin-shaped three-dimensional model for punching such as 1101 to 1103 shown in FIG. 11 is generated, and the assembly is edited and stored so that the assembly referring to the three-dimensional model (part 801) is referred to. Thus, 801 and 1101 to 1103 indicated by 1100 are displayed on one display screen. 1110 of FIG. 11 shows an image when an unnecessary part 802 (removal part) is punched and removed.

  The predetermined positions 1102 and 1103 in FIG. 11 indicate the positions of pin-shaped parts (positions 1102 and 1103) that are part of the three-dimensional model for punching, and the pin-shaped parts are used for punching. This is a position in contact with the base 1101 in the three-dimensional model. In other words, the distance from the center point of the hole to the Z-axis direction is the distance (predetermined distance) by which the pin-shaped component contacts the base member (component).

  The position on the base member where the pin-shaped component is in contact is the position on the member where the pin-shaped component is placed. That is, the overlap determination tool determines the position on the member of the pin-shaped part that strikes the back object through the hole.

  If the distance between the 801 component and the 1101 component is constant, the position in the height direction (Z-axis direction) where the pin-shaped component is arranged is determined in advance, and the pin-shaped component is arranged. You may make it determine the position of a vertical axis | shaft and a horizontal axis direction (X-axis, Y-axis direction) to the position of the hole which should punch out components of a back surface.

  The overlap determination tool executes the processing of steps S609 to S611 for all hole objects in the hole objects that are identified and acquired in step S608 and for which the corresponding three-dimensional model is not arranged in the three-dimensional space. Judge whether it is finished.

  If there is an unprocessed hole object, one unprocessed hole object is acquired, the process returns to step S609, and the processes of S609 to S611 are executed. If all the hole objects have been processed, the processing in FIG. 6 is terminated. The above is the description of FIG.

  According to the process of FIG. 6, a new part corresponding to a hole overlapping with another part can be easily generated and arranged.

  Moreover, the position on the member which arrange | positions the new component for driving out the component in the back side through a hole can be determined.

  Note that the present invention may be realized by switching the determination timings of step S512 and step S513 in FIG.

  Specifically, when the overlap determination tool determines in step S511 in FIG. 5 that the line segment of the back object being processed is the last line segment among the unprocessed line segments that form the back object. If (YES in step S511), the process proceeds to step S513.

  In step S513, it is determined whether all hole objects in the object information 710 have been determined to overlap with the back object being processed. When it is determined that the overlap with the back object being processed has been determined for all the hole objects in the object information 710, the process proceeds to step S518, and when it is determined that the determination has not been made (that is, If a hole object that has not been determined whether or not there is an intersection with a virtual straight line drawn from the line segment of the wavefront object remains), the process proceeds to step S512.

  In step S512, the overlap determination tool determines whether all the back objects in the back object information 720 have been processed (step S512). That is, it is determined whether the number of intersections with the hole object has been counted for all the back objects. If there is an unprocessed back object, the process proceeds to step S517 to acquire one unprocessed back object, and the process proceeds to step S503. If all the back objects have been processed, the processing in FIG. 5 is terminated.

<Second Embodiment>
Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, it is determined based on the hole whether the hole overlaps with the component on the back side of the component having the hole.

  In the three-dimensional model in which the hole is completely covered by the back part, as shown in the relationship between the back object 1801 and the hole object 1802 in FIG. 18, for example, all the vertices of the back object are located outside the hole. There may be. That is, even if a virtual line segment is subtracted from a point on the outline of the back object (eg, the start point of each line segment in each object), the number of intersections between the virtual line segment and the back object may be 0 or even. .

  The overlap determination process based on the hole in the second embodiment is useful when, for example, specifying a part punched part in a three-dimensional model in which the hole completely covers the part on the back. It is.

  With reference to FIG. 17, the flow of the overlap determination process in the second embodiment of the present invention will be described. In the second embodiment, the process of FIG. 17 is executed instead of the process of FIG. 5 in the first embodiment.

  The processing shown in each step of FIG. 17 is executed by the CPU 201 of the PC 100 using the function of CAD software or overlap determination tool installed in the PC 100.

  Descriptions of diagrams, processes, data, screens, and parts that are common to the first embodiment are omitted.

  The processing in step S1701 is the same as the processing in step S501 in FIG. Further, the process of step S1702 is the same as the process of step S502 of FIG. Therefore, explanation is omitted.

  The overlap determination tool acquires one unprocessed line segment from the line segments of the object (hole object) acquired in step S1701 (step S1703), and initializes a counter indicated by 730 in FIG. 7 (step S1704). ), The object name of the hole object acquired in step S1701 (or step S1718 described later) is the object name 731, the name of the line segment acquired in step S1703 (or step S1716 described later) is the line name 732, and step S1702 ( Alternatively, the object name of the back object acquired in step S1717) described later is inserted into the count object name 733 and stored.

  The overlap determination tool generates, for example, a virtual straight line inclined at an arbitrary angle of an elevation angle of 1 degree or more outside the hole, with the direction of the target line segment as 0 degrees, as shown by 1803, 1804 in FIG. As shown in 1803, it arrange | positions to the start point of the line segment acquired by step S1703 (step S1705).

  If the hole is circular, the starting point of the line segment is one point. At the start point of the circular hole, a virtual line having a contact point with the start point is created, and the virtual line is drawn at an arbitrary angle toward the outside of the hole with the direction of the virtual line being 0 degrees.

  For example, it is assumed that the arbitrary angle (predetermined elevation angle) is 60 degrees. It is assumed that the predetermined elevation angle value is stored in the external memory of the PC 100 and can be arbitrarily changed by a user operation via a setting screen (not shown). The overlap determination tool acquires one unprocessed line segment among the line segments of the back object acquired in step S1702 (step S1706).

  The overlap determination tool determines whether or not there is an intersection between the virtual straight line 1803 arranged in step S1705 and the line segment constituting the acquired back object (step S1707), and if there is an intersection, count the number of intersections 734 of the counter 730 by one. Up (step S1708), and the process proceeds to step S1709. If there is no intersection, the process proceeds to step S1709.

  The overlap determination tool determines whether the back object line segment (710 line segment) for which the presence or absence of the intersection is determined in step S1707 is the last line segment of the back object line segment (step S1709). If an unprocessed line segment still remains, one unprocessed line segment is acquired from the hole object line segments acquired in step S1702 (step S1715), and the process proceeds to step S1707.

  When all the line segments of the back object acquired in step S1702 have been processed, the overlap determination tool determines whether the value of the intersection number 734 of the counter 730 is an odd number or an even number (step S1710).

  When the number of intersection points is an odd number, as shown in the relationship between 1801 and 1802 in FIG. 18, the hole object being processed acquired in step S1701 (or step S1718 described later) is the step S1702 (or step S1717 described later). It is determined (determined) that the virtual straight line is overlapped with the crossed back object acquired in step S1714, and the process proceeds to step S1714.

  Further, the hole object acquired in step S1701 (or the hole object acquired in step S1718 described later) is a hole at a position overlapping with the object on the back surface, and is specified as a place where the back model is punched, and stored in the external memory. Store (step S1714). Specifically, as indicated by reference numeral 740 in FIG. 7, which model (part name 741) and which object (target part 742) indicates the location to be punched are stored.

  That is, it is determined that there is a back side part that can be punched through the hole for the hole having an odd number of intersections 734 of the counter 730, and the back side part is determined to be punched through the hole. To do.

  If the number of intersection points is even or 0, as shown in FIG. 18, it is determined that the hole object being processed acquired in step S1701 (or step S518 described later) does not overlap with the back object to be determined (determined). And the process proceeds to step S1711.

  The overlap determination tool determines whether the line segment of the hole object being processed is the last line segment among the unprocessed line segments that form the hole object (step S1711). If there is an unprocessed line segment, one unprocessed line segment is acquired from the line segments of the hole object being processed (step S1716), and the process proceeds to step S1704.

  When all the line segments constituting the hole object being processed have been processed, the overlap determination tool determines whether all the hole objects in the back object information 720 have been processed (step S1712). If there is an unprocessed back object, one unprocessed back object is acquired (step S1717), and the process proceeds to step S1703.

  Thereafter, all the line segments of the hole object being processed are determined as unprocessed line segments, and the processes after step S1703 are executed for the hole object being processed and the back object newly acquired in step S1717. If all the back objects have been processed, the process proceeds to step S1713.

  The overlap determination tool determines whether all hole objects in the object information 710 have been processed (step S1713).

  That is, a hole that is not determined whether it overlaps with the back object in a hole (for example, a hole opened on the upper surface in the height direction) opened on the front surface of the predetermined part X specified by the user operation Determine if there is any. If there is an unprocessed hole object, an unprocessed hole object is acquired (step S1718), and the process proceeds to step S1702. If all hole objects have been processed, the processing in FIG. 17 ends. The above is the description of FIG.

  As described above, according to the second embodiment of the present invention, the position where the hole of the part overlaps with another part can be easily achieved even if the other part covers the hole. It is possible to provide a mechanism that can identify and easily make a decision according to the presence / absence of another part.

  The first embodiment and the second embodiment described above may be executed in combination. For example, as the overlap determination process in step S409 of FIG. 4, first, the process of FIG. 5 of the first embodiment is executed. Thereafter, the processing of FIG. 17 in the second embodiment is performed for a hole determined not to overlap the back object in the processing of FIG. 5 (a hole determined to have no punchable part on the back side). Run.

  The holes determined not to overlap the back object are the holes opened in the front surface of the predetermined part X (for example, holes opened in the upper surface in the height direction) acquired in step S407, as shown in FIG. 7 is a hole object that is not included in the punching target portion 740 (a list of holes determined to have an object on the back) in FIG.

  By combining and executing the processing of FIG. 5 and the processing of FIG. 17, for example, a three-dimensional model in which a design in which the back object overlaps part of the hole and a design in which the back object covers all of the hole is mixed. In this case, it is possible to increase the accuracy of determining the overlap between the hole and the part.

  In the description of the second embodiment described above, a virtual straight line having a predetermined elevation angle is drawn from the start point of the line segment of the hole toward the outside of the hole. However, as shown by 1805 in FIG. A virtual straight line with a predetermined elevation angle may be drawn inward.

<Third Embodiment>
A third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, the start point of the virtual straight line can be set in addition to the start point of the hole or the back object, and the presence or absence of another part that can be punched through the hole of the part on the back side of the part can be easily established. Provide an identifiable mechanism.

  For example, although there is another part that can be punched through the hole of the part on the back side of the part, the back object does not overlap the start point of the side of the hole, and the side of the back object The starting point may not be in the hole.

  In other words, even if the number of intersections between the back object and the virtual line is obtained by subtracting the virtual line from the start point of the hole side, the number of intersections between the hole and the virtual line is obtained by subtracting the virtual line from the start point of the side of the back object. However, even though another part that can be punched through the hole of the part actually exists, it may be determined that the corresponding part does not exist.

  For example, according to the diagram 2100 in FIG. 20, when a virtual line is drawn from the starting point of the hole, the number of intersections between the virtual line and the side of the back object is 0 or an even number. When the virtual line is drawn from the starting point of the back object in 2100, the number of intersections between the virtual line and the side of the hole is 0 or an even number.

  In the third embodiment, the starting point of the virtual straight line can be set based on a certain reference, so that the virtual straight line is on the back side of the part compared to the case where the virtual straight line is simply drawn from the starting point of the hole or the back object. Provided is a mechanism capable of easily making a determination according to the presence / absence of another part while improving the accuracy in the process of specifying the presence of another part that can be punched through the hole of the part.

  In the three-dimensional model in which the hole is completely covered by the back part, as shown in the relationship between the back object 1801 and the hole object 1802 in FIG. 18, for example, all the vertices of the back object are located outside the hole. There may be. That is, even if a virtual line segment is subtracted from a point on the outline of the back object (eg, the start point of each line segment in each object), the number of intersections between the virtual line segment and the back object may be 0 or even. .

  The overlap determination process based on the hole in the second embodiment is useful when, for example, specifying a part punched part in a three-dimensional model in which the hole completely covers the part on the back. It is.

  With reference to FIG. 19, an example of the setting process of the starting point of the virtual straight line in the third embodiment of the present invention will be described. Note that the processing shown in each step of FIG. 19 is executed by the CPU 201 of the PC 100 using the function of the overlap determination tool installed in the PC 100.

  Descriptions of diagrams, processes, data, screens, and parts that are common to the first and second embodiments are omitted.

  The process in FIG. 19 is executed, for example, after step 504 in FIG. 5 and before the process in step S505. That is, in the first embodiment, this is a process that can set the starting point of the virtual straight line based on a certain reference.

  The overlap determination tool acquires a predetermined interval (distance) value stored in the external memory of the PC 100 (step S1901). The predetermined interval value (Nmm) is a reference value of the distance interval for setting the starting point of the virtual straight line on the outline of the back object. For example, a width narrower (shorter) than the hole width or the component width is set. It shall be. The reference value can be changed and set by a user operation via a setting screen (not shown).

  The overlap determination tool measures the hole width of each hole object in the object information 710 and specifies the shortest width. If the hole object is circular, the diameter of the circle is specified as the width of the hole object and stored in 710 in association with the hole object.

  When the hole object is not circular, for example, when the hole opened in the component 2103 is a rectangular hole as indicated by 2101 in FIG. 21, the start point, end point, and middle point are extracted for each side (line segment) of the hole object. Then, a virtual straight line is drawn from each point in a direction perpendicular to the side. The intersection point between the contour line of the hole object and the virtual straight line is specified, and the two-dimensional position (X, Y coordinate) of the intersection point is specified.

  The length of the longest virtual straight line among the virtual straight lines up to the intersection is stored in the RAM as a width corresponding to the side of the hole object, and is the longest among the widths corresponding to all the sides of one hole object. The short width is determined (specified) as the width of the hole object and stored in 710.

  Then, the overlap determination tool acquires the shortest width value among all the hole widths stored in the object information 710 (step S1902). For example, in 2100 of FIG. 21, 2.1 mm is the shortest width of the hole object 2101.

  The overlap determination tool compares the reference value acquired in step S1901 with the shortest hole width acquired in step S1902, and determines whether or not the shortest hole width is shorter than the reference value (step S1903). ).

  If the reference value is shorter, the process proceeds to step S1904. If the shortest hole width is shorter, the process proceeds to step S1905.

  In step S1904, on the side of the back object acquired in step S503, a virtual point that is the starting point of the virtual straight line is set at an interval indicated by the reference value from the starting point to the ending point of the side. For example, the name of the side and the X and Y coordinates of the virtual point are associated with each other and stored on the RAM (step S1904).

  In step S1905, on the side of the back object acquired in step S503, a virtual point that is the starting point of the virtual straight line at an interval shorter than the width of the shortest hole specified in step S1902 from the start point of the side to the end point. Set. For example, the name of the side and the X and Y coordinates of the virtual point are associated with each other and stored in the RAM (step S1905).

  An example of the back object is shown at 2102 in FIG. In addition, examples of virtual points are indicated by 2111 to 2114 in 2110 of FIG. 2110 is an example in which the starting point of the virtual straight line is set using the shortest hole width. The distance from the start point 2115 of the side to the virtual point 2114 is determined as 2.0 mm, which is 0.1 mm shorter than the shortest hole width of 2.1 mm, and a virtual point is set. The distance between 2113 and 2114 is also 2.0 mm.

  Thereafter, in step S505 in FIG. 5, the overlap determination tool draws a virtual line at a predetermined elevation angle with the virtual point set in step S1904 or S1905 and the start point of the side of the back object as the start point of the virtual line. An example of a virtual straight line is shown at 2120 in FIG.

  The overlap determination tool executes the processes of steps S507 to S511 until it is determined in step S510 that the number of intersections with the hole object is an odd number for each virtual straight line. In step S514, it is determined that the hole acquired in step S501 is a hole in which another part on the back side can be launched, and is stored in 740 in FIG.

  A hole having zero or an even number of intersections with any virtual straight line is a hole that does not overlap the part. That is, it is determined that there is no back side part that can be punched through the hole.

  By executing the above-described processing, as shown by 2120 in FIG. 21, the overlapping hole and the back object in which the number of intersections with the hole is 0 or even in the virtual straight line drawn from the starting point of any side Also, as shown by an imaginary straight line 2121, the intersection with the hole can be specified as an odd number. That is, the accuracy of the overlap determination is improved as compared with the case where the overlap between the hole and the back object is determined by drawing a virtual straight line from only the start point.

  Next, an example of a virtual straight line start point setting process in the third embodiment of the present invention will be described with reference to FIG. Note that the processing shown in each step in FIG. 20 is executed by the CPU 201 of the PC 100 using the function of the overlap determination tool installed in the PC 100.

  Descriptions of diagrams, processes, data, screens, and parts that are common to the first and second embodiments are omitted.

  The process in FIG. 20 is executed after, for example, step 1704 in FIG. 17 and before the process in step S1705. That is, in the second embodiment, this is a process that can set the starting point of the virtual straight line based on a certain reference.

  The overlap determination tool acquires a value of a predetermined interval (distance) stored in the external memory of the PC 100 (step S2001). This interval is a reference value of the distance interval for setting the starting point of the virtual straight line on the outline of the hole object. The reference value can be changed and set by a user operation via a setting screen (not shown).

  The overlap determination tool measures the width of each back object in the back object information 720 and specifies the shortest width. When the back object is circular, the diameter of the circle is specified as the width of the back object, and stored in 720 in association with the back object.

  When the back object is not circular, for example, when it is a rectangular object as indicated by 2102 in FIG. 21, the start point, end point, and middle point are extracted for each side (line segment) of the back object, and the corresponding point is extracted from each point. A virtual straight line is drawn in a direction perpendicular to the side. The intersection point between the contour line of the back object and the virtual straight line is specified, and the two-dimensional position (X, Y coordinate) of the intersection point is specified.

  The length of the longest virtual line among the virtual lines up to the intersection is stored in the RAM as the width corresponding to the side of the back object, and the longest of the widths corresponding to all the sides of one back object. The short width is determined (specified) as the width of the back object and stored in 720.

  Then, the overlap determination tool acquires the shortest width value among the widths of all the back objects stored in the back object information 720 (step S2002). For example, in 2150 of FIG. 21, 1.1 mm is the shortest width of the back object 2102.

  The overlap determination tool compares the reference value acquired in step S2001 with the shortest back object width acquired in step S2002, and determines whether or not the shortest back object width is shorter than the reference value ( Step S2003).

  If the reference value is shorter, the process proceeds to step S2004, and if the shortest hole width is shorter, the process proceeds to step S2005.

  In step S2004, a virtual point that is the starting point of the virtual straight line is set on the side of the hole object acquired in step S1703 from the start point to the end point of the side at intervals indicated by the reference value. For example, the name of the side and the X and Y coordinates of the virtual point are associated with each other and stored on the RAM (step S2004).

  In step S2005, a virtual point on the side of the hole object acquired in step S1703 is set as a virtual straight line start point at an interval shorter than the shortest back object width specified in step S2002 from the start point to the end point of the side. Set. For example, the name of the side and the X and Y coordinates of the virtual point are associated with each other and stored in the RAM (step S2005).

  An example of a virtual point is shown at 2161 to 2168 in 2160 of FIG. 2160 is an example in which the starting point of the virtual straight line is set using the shortest back object width. The distance from the edge start point 2169 to the virtual point 2161 is determined as 1.0 mm, which is 0.1 mm shorter than the shortest hole width of 1.1 mm, and the virtual point is set. The distance between 2161 and 2162 is also 1.0 mm.

  Thereafter, in step S1705 of FIG. 17, the overlap determination tool draws a virtual line at a predetermined elevation angle with the virtual point set in step S2004 or S2005 and the start point of the side of the hole object as the start point of the virtual line. An example of the virtual straight line is shown by 2170 in FIG.

  The overlap determination tool executes the processes of steps S1707 to S1711 for each virtual straight line until it is determined in step S1710 that the number of intersections with the back object is an odd number. In step S1714, it is determined that the hole acquired in step S1701 is a hole in which another part on the back side can be launched, and is stored in 740 in FIG.

  In any imaginary straight line, a hole having 0 or an even number of intersections with a back object is a hole that does not overlap with a part. That is, it is determined that there is no back side part that can be punched through the hole.

  By executing the above-described processing, as shown by 2170 in FIG. 21, the overlapping hole and the back surface in which the number of intersection points with the back object is 0 or even in the virtual straight line drawn from the start point of any side Also in the object, as shown by the virtual straight line 2171, the intersection with the hole can be specified as an odd number. That is, the accuracy of the overlap determination is improved as compared with the case where the overlap between the back object and the hole is determined by drawing a virtual straight line from only the start point.

  As described above, according to the third embodiment of the present invention, the virtual straight line can be set from the start point of the hole or the back object by enabling the virtual straight line start point to be set based on a certain reference. Compared to the case, it is possible to improve the accuracy in the process of specifying the presence of another part that can be punched out through the hole of the part on the back side of the part, and to easily make a decision according to the presence or absence of the other part. Possible mechanisms can be provided.

<Other embodiments>
In the above-described embodiment, an example in which unnecessary parts are punched and removed has been described. However, for example, as shown in FIG. You may use this invention for.

  As shown in 1204 in FIG. 13, when a back object 1204 larger than the hole 1202 is in a position overlapping the hole 1202 on the back surface of the 1201, the hole is used as a punching target (target for inserting a bonding model (screw)). It may be determined.

  For example, using the three-dimensional model 1201 instead of 801, the outline of the hole 1202 is acquired in step S501. In step S503, the contour of 1204 is acquired. The contour of the model in FIG. 12 is shown at 1300 in FIG. The overlap determination tool determines whether there is an outline of the back object (1204 in FIG. 13) that includes (encloses) the outline of the hole for each acquired outline of the hole (that is, a position where the hole and the back object overlap) If it is determined that they are overlapping, the process proceeds to step S514, and if it is determined that they are not overlapping, the outline of the unprocessed back object is acquired, The above overlap determination process is repeated until there is no unprocessed back object, or the overlap determination process ends for all hole objects, or the process ends when the process of step S514 ends, or in step S611. 12 is a screw model corresponding to the hole 1202, 1205 in FIG. 12, and a driver model corresponding to the screw. 203 generates and directs the CAD software to place in position.

  The overlap determination process is performed by the process of FIG. 17 (particularly, step S1710), for example.

  For example, when it is determined by the overlap determination process that the hole and the back object overlap, it is determined that the outline of the back object surrounds the hole.

  When the outline of the back object surrounds the hole (when the number of intersections of the back object and the hole is an odd number), the processing may be shifted to step S1714. Thereafter, in step S611 in FIG. 6, the CAD software is instructed to generate 1205 in FIG. 12 which is a screw model corresponding to the hole 1202 and 1203 which is a driver model corresponding to the screw and to place it at a predetermined position. You may make it do.

  Thereby, even when another component larger than the hole of the component is positioned so as to overlap the hole, a mechanism capable of easily specifying the position of the hole can be provided.

  Also, a plurality of new parts corresponding to holes that overlap with other parts can be easily generated and arranged.

  In the embodiment described above, in step S404, the outline of a model whose file name includes the back character string is requested and acquired. For example, a list of models including the front character string is displayed. Instead of the back object described in the above-described embodiment, the overlap determination may be performed using a model outline (object) including the character string of the front in the file name instead of the back object described in the above-described embodiment. Thereby, for example, an overlap between a part 1503 as shown in FIG. 15 (a model including a front character string in the file name) and a hole 1502 of a predetermined model 1501 on the back side is determined, and is shown at 1510 in FIG. As described above, the hole 1502 at a position overlapping the object on the front side can be determined and displayed in step S514 (or step S1714).

  Therefore, even when the part 1503 to be bonded to 1501 is on the front side, the position of the hole 1502 (for example, screw hole) opened in 1501 can be automatically determined. In addition, identification display can be performed.

  In the above-described embodiment, in the main dialog 1610 displayed in step S403 of FIG. 4, when the selection of the radio button 1612 is accepted, an operation of pressing the “contour request” button 1613 is accepted. Although a file (three-dimensional model) opened by CAD software is accepted as a target for overlap determination processing, an arbitrary three-dimensional model may be specified as a target for overlap determination processing by a user operation. Good.

  Specifically, a storage device that accepts the selection of the radio button 1611 of the main dialog 1610 and stores it in the external memory of the PC 100 by accepting the pressing of the “reference” button, or the PC 100 such as the server 200 can communicate and refer to. The file list of the 3D model stored in is displayed.

  The file name and storage location of the three-dimensional model selected from the file list are held in the RAM 203, and when the “contour request” button 1613 is pressed, the file name and storage location of the selected three-dimensional model are converted into CAD software. Send to and instruct them to deploy.

  The CAD software expands the file according to the instruction. Further, the overlap determination tool shifts the processing to step S404, and requests the CAD software for the contour of the three-dimensional model of the file developed in accordance with the instruction. The details of the contour request method have been described above in the description of step S404, and the description thereof will be omitted.

  Further, a position that is a predetermined distance away from the hole in the axial direction of the hole (a hole 740 in FIG. 7) that is a target for the part on the back surface may be determined as the position of the part for launch. The axial direction of the hole is obtained for each hole by inquiring to CAD software.

  In addition, a hole penetrating from the upper surface to the lower surface is extracted, the outline of the penetrating hole is obtained by requesting the CAD software, and stored in the object information 710 as an overlap determination processing target. Good. This is because, in order to launch a part on the back side, it is necessary that a hole penetrates toward the back side of the front part (for example, from the upper surface to the lower surface).

  As described above, according to the present invention, it is possible to provide a mechanism that can easily identify a position where a hole of a part and another part overlap.

  In addition, it is possible to provide a mechanism that can easily determine whether there is another part that can be punched through the hole of the part on the back side of the part.
