Description

  The present invention creates a series of machining information of outline machining and precision machining for a three-dimensional model part in a CAD / CAM system that supports machining (production) preparation for machining by an NC or CNC machine tool or the like. The present invention relates to a machining information creation apparatus, method, and program.

  Conventionally, three-dimensional CAD (Computer Aided Design: computer-aided design system) equipment designed 3D design shape data is read as input data, and based on the read shape data, a part of the design shape ( By adding manufacturing information such as processing tools and processing conditions (local processing manufacturing information or total manufacturing information) to the whole or process design for work activities by computers, work design, and even automatic There is a three-dimensional CAM (Computer Aided Manufacturing) system that supports production preparation by creating a program for a machine tool.

  As a method of adding manufacturing information to the above-described design shape, there is a method of selecting one surface having a three-dimensional shape when adding to a partial shape. In the case of the entire shape, a method of selecting the design origin of the three-dimensional model is common.

  As automatic machine tools, NC (Numerical Control: a system that controls the movement of machine tools by numerical information and servomechanism) and CNC (Computer (ized) Numerical (ly) Control (led): computer numerical control) Machine tools are common.

  For example, Patent Document 1 discloses detailed contents regarding generation of an NC machining program. However, there is no disclosure regarding a method for creating a target model as a final target product from the intermediate stage to the final stage, which is simply a technique related to the intermediate stage model creation.

  The creation of the target model of the final target product from the intermediate stage to the final stage is, for example, the cutting allowance of the local portion included in the three-dimensionally designed shape (conventionally performed by skilled processing engineers). It is a processing process with final finishing by precision finishing processing to the part including white.

  By the way, the same precision surface finishing is performed on the 3D model processed by the shape data of the 3D design including the machining allowance created by the CAD as described above when the skilled processing engineer performs later. In the case where the automatic control is performed by the axis control, conventionally, the process is divided into two steps.

  As described above, the three-dimensional solid processing and the two-dimensional precision surface processing (the same applies to the three-dimensional precision processing) are performed in two steps. The conventional CAM system is designed in three dimensions. This is because only a machining program according to the shape can be created.

  Therefore, even if the shape data of the three-dimensional design including the machining allowance for the three-axis control, the position information obtained by cutting the portion of the machining allowance for the two-axis control, and the precision finishing information are provided to the CAM at one time, the above-described CAM Since the machining information output from the CAM to the machine tool is processed and edited in correspondence with the external dimensions, the machining result as expected cannot be obtained.

  6 (a) to 6 (d) are diagrams for explaining the operation of the machine tool according to a program created by such a conventional CAM system. FIG. 6 (a) shows an example of the three-dimensional shape model 1 to be finally obtained. In the three-dimensional shape model 1, an upper body 3 is formed on a base 2, and the front surface (lower surface in the drawing) of the base 2 is a precision machined surface 4 that requires precision finishing.

  FIG. 6B shows the three-dimensional shape data 5 created by the CAD system. Although the shape of the upper body part 3 is not changed, the shape of the base 2a is an outer dimension in which a built-up portion 6 is added to the precision machining surface 4 by a machining allowance, and the front surface of the base 2 Has a built-up surface 7.

  The CAM system that has received the above-described three-dimensional shape data 5 edits the build-up surface 7 outside the precision machining surface 4 as an external dimension when three-dimensionally machining the front surface of the base 2 (2a). Thus, in the CAM system, since the front surface dimension of the base 2 is edited as the overlay surface 7, the precision machining information that should have been added to the precision machining surface 4 is also processed as processing information for the front surface dimensions of the base 2. Assigned to the overlay surface 7.

  As a result, a 3D model (similar to the 3D shape data 5) before precision finishing is created by the NC or CNC machine tool using this program based on the 3D shape data 5, and then switched to 2-axis control with a precision finishing blade. If the machining is continued, the operation of the precision finishing blade does not act on the position of the precision machining surface 4 but acts on the build-up surface 7 as shown by the operation locus 8 in FIG.

  Therefore, in the conventional CAM system, when the processing methods are divided into a plurality of processing methods such as the above-described external finishing and partial precision finishing, a plurality of three-dimensional shapes are processed according to the plurality of processing methods. It was necessary to prepare a program and perform processing in two steps.

That is, the machining process by the machining information of the external machining for machining into the shape of the three-dimensional shape model before the precision secondary machining with overlaying shown in FIG. 6 (b) by the CAM system, and FIG. 6 (d) As shown in the figure, the machining process that cuts the built-up portion of the machining allowance by the 2-axis control and processes the precision finishing 8 at the position of the precision machining finished surface 4, such as the outer shape machining and the precision finishing machining. It was necessary to divide into two.

Is possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
FIG. 1 is a functional block diagram showing a schematic configuration of a machining information creation device according to the first embodiment. A machining information creation computer 10 as a machining information creation device is composed of, for example, a personal computer, and includes a control unit 11, a display unit 12, an input unit 13, a main storage device 14, an external storage device 15, and the like.

The control unit 11 creates machining information as described later by executing the three-dimensional CAD / CAM program 100 mounted on the main storage device 14.
In the case of the present embodiment, the CAD unit 110 of the three-dimensional CAD / CAM program 100 includes a design unit 111, a processing location selection unit 112, a processing range drawing unit 113, a manufacturing information addition unit 114, an automatic shape editing unit 115, a design. It consists of program modules such as the information output unit 116.

  The CAM unit 120 includes program modules such as a manufacturing information acquisition unit 121, an NC program calculation unit 122, an NC program sort unit 123, an NC program combination unit 124, and an NC program output unit 125.

  The external storage device 15 includes a storage area as a machining location storage unit 130 that stores a result executed by the control unit 11 based on a program stored in the main storage device 14. The external storage device 15 includes a storage area as a manufacturing information DB unit 131 that stores manufacturing information added by the manufacturing information adding unit 114.

  The three-dimensional CAD / CAM program 100 stored in the main storage device 14 includes a general three-dimensional CAD / CAM program. This program is used to create a three-dimensional shape model and to produce a three-dimensional shape model. Information such as end mill movement and motion conditions can be created.

  The input unit 13 includes a keyboard, a pointing device, and the like. The keyboard includes a plurality of operation keys for inputting numbers, characters, and various commands, and outputs status signals of these operation keys to the control unit 11. . The pointing device is composed of a mouse, for example, and designates an arbitrary position on the screen displayed on the display device of the display unit 12.

  Based on the start instruction input from the keyboard of the input unit 13 while controlling the above-described units, the control unit 11 reads a CAD / CAM system program from the external storage device 15, for example, and reads the read CAD / CAM system Based on the program and the data input from the keyboard of the input unit 13, a series of machining information for outline machining and precision machining for the parts of the 3D model is created, and the created machining information can be output at any time. Are stored in a predetermined storage area of the main storage device 14.

FIG. 2 is a flowchart for explaining the operation of machining information creation processing by the machining information creation computer 10 having the above-described configuration.
FIGS. 3A to 3D are diagrams schematically showing the information sequentially added to the machining information in accordance with the machining information creation process described above.

  In FIG. 2, first, shape design by three-dimensional CAD is performed by the design unit 111 in the three-dimensional CAD / CAM program 100 (step S01). In this processing, a three-dimensional CAD system is activated, and a three-dimensional shape model (product model) is displayed on the display unit 12 by shape design based on input of image data manually input from the input unit 13 and input of dimension data. .

  FIG. 3A shows an example of the shape of the product model created by the process in step S01. A three-dimensional shape model 20 shown in FIG. 3A has a base 21 whose upper and lower surfaces are substantially square and has a height shorter than the length of the side of the square, and a base 21 at the center of the upper surface of the base 21. The upper body portion 22 is formed integrally with the base 21 and is smaller than the square on the upper surface of the base 21 and has a height shorter than the length of the side of the square.

  Subsequently, in FIG. 2, an instruction (selection) of a local processing / manufacturing site is performed, and information indicating the processing site selected by the processing site selection unit 112 in the three-dimensional CAD / CAM program 100 is stored in the processing site storage unit 130. Processing is performed (step S02).

  This process is a process of designating a locally processed manufacturing site where a secondary process such as precision finishing is performed later on the shape of the three-dimensional shape model 20 designed in the process of step S01. Further, in this process, for example, a message window such as “Please specify a local processing manufacturing site” is displayed on the display unit 12 to prompt the user to specify the local processing manufacturing site.

  At this time, as shown in FIG. 3 (b), the user clicks one side surface 22a of the upper body part 22 which is a locally processed manufacturing site with a mouse or the like to change the color of the one side surface 22a (first It may be possible to indicate a local processing manufacturing site by performing a first color conversion process.

  Subsequently, the control unit 11 creates a shape that defines the machining range for the local machining manufacturing site instructed in the process of step S02 by the machining range drawing unit 113 in the three-dimensional CAD / CAM program 100 ( Step S03).

  In this process, the shape defining the processing range is basically the same surface shape as the instructed local processing manufacturing site (one side surface 22a) shown in FIG. Note that, depending on the intended use, the user can change the surface shape shown on the one side surface 22a of FIG.

  Next, with respect to the processing range of the local processing manufacturing site created in step S03 (referred to as the local processing manufacturing range, which is basically the same range as the shape of the one side surface 22a), the local processing manufacturing information is converted into three-dimensional CAD / The information is added by the manufacturing information adding unit 114 in the CAM program 100 (step S04). Manufacturing information added by the manufacturing information adding unit 114 is stored in the manufacturing information DB unit 131 in the external storage device 15.

  In FIG. 3C, the color of the processing range specified in step S03 of the one side surface 22a specified in FIG. 3B is changed (after the second color conversion process), and FIG. ) Shows that local processing manufacturing information 22b is added to one side surface 22a.

  FIG. 4 is an example of information included in the local process manufacturing information 22b. In the example shown in FIG. 4, the name of information “local processing manufacturing information” is described in the “Title” section. The following Tools section contains the tool number ID = 1, the tool diameter DIAM = 3, the tool length LENGTH = 6, the number of tool blades NUM-OF-TEETH = 4 Instructions for machining by two-axis control are described over two lines of designation of Operation and Type = Profile.

  Further, the following Feed section includes an infeed amount instruction of SideStep = 1.5, a feed speed instruction of Feed = 200, a depth direction instruction of DepthStep = 0.3, and a tool blade of SpindleSpeed = 5000. Instructions on the number of revolutions are described.

  When such local processing / manufacturing information 22b is added to the local processing / manufacturing range, a tool having a large diameter is used depending on the size (area) of the processing range, for example, when the area of the processing range exceeds a certain value. It is also possible to switch the local processing manufacturing information 22b to be added. Naturally, when the local process manufacturing information 22b is switched, the information included in the local process manufacturing information 22b as shown in FIG. 4 is also switched.

  Following the above, the shape of the local location (local machining manufacturing range) is edited by the shape automatic editing unit 115 in the three-dimensional CAD / CAM program 100 (step S05). In this process, as shown in FIG. 3 (d), the entire area before the local processing (secondary processing) in which the build-up portion 22c is added to the local processing manufacturing range (the same range as the shape of the one side surface 22a). The shape (entire 3D shape) is edited.

  The purpose of this editing is fleshing so that the shape that is desired to be locally processed later (the shape shown in FIG. 3B) is not processed by the overall shape processing. The fleshing surface (the surface to which the build-up portion 22c is added) can be switched according to the size (area) of the indicated portion, as in the local processing manufacturing range.

  Next, the entire manufacturing information is added to the entire three-dimensional shape by the manufacturing information adding unit 114 in the three-dimensional CAD / CAM program 100 (step S06). Since the entire manufacturing information for the entire three-dimensional shape (the shape shown in FIG. 3 (d)) in this process can be understood from which direction the entire three-dimensional shape is processed, the manufacturing origin of the entire three-dimensional shape (processing It is added to a surface that is not hidden when the 3D shape is viewed from the processing direction.

  The added overall manufacturing information includes information as shown in FIG. 4 as with the local processing manufacturing information 22b. Therefore, unlike the above-described local manufacturing information addition, manufacturing information can be added without performing the processing of the processing location selection unit 112 and the processing range drawing unit 113.

  Information input or calculated in steps S01 to S06 is sequentially stored in a predetermined storage area of the main storage device 14. Subsequently, the added whole manufacturing information is taken out from the processing location storage unit 130 in the external storage device 15 and developed by the CAM unit 120 (step S07).

  FIG. 5 is a diagram illustrating an example of a machining process developed in the three-dimensional CAM system. In these local shape machining step 23 and overall shape machining step 24, designation of tools, machining conditions, machining order, coordinates, etc. are described.

  In the example shown in FIG. 5, there are two processing steps, local shape processing 23 and overall shape processing 24. If there are multiple pieces of manufacturing information to be added, the same number of processing steps are added. can do.

  If the same manufacturing information is mistakenly added in the step of adding local processing manufacturing information in step S04, one of the information is thinned out in the processing in step S07.

  Subsequently, the machining program calculation is started by the NC program calculation unit 122 in the three-dimensional CAD / CAM program 100 (step S08). In the following processing, a machining program is calculated based on the added overall manufacturing information.

  First, the entire three-dimensional shape including the shape edited in step S05 is set as the calculation application range (step S09). In this process, a machining program is generated by including the shape edited in step S05 (the shape to which the overlaying portion 22c shown in FIG. 3 (d) is added) in the entire shape (entire three-dimensional shape). It is set to perform the operation.

  Subsequently, a calculation for generating a machining program is performed on the shape application range of the calculation based on the entire manufacturing information added in the process of step S06 (step S10). Then, the generated machining program (a machining program for manufacturing a model before the secondary machining (the entire three-dimensional shape) shown in FIG. 3D) is output (step S11).

  This output process is a process of storing the machining program as a first program file in a predetermined temporary storage area of the main storage device 14. Next, the machining range whose shape is defined in the process of step S03 is set as the calculation application range (step S12).

  Subsequently, a calculation for generating a machining program for local production is performed on the machining range set as the calculation application range by using the local machining production information 22b added in the process of step S04 (step S13).

  Then, the machining program obtained as a result of the calculation (the build-up portion 22c of the entire three-dimensional shape model shown in FIG. 3 (d) is converted into one based on the local machining manufacturing information 22b shown in FIG. 3 (c). A machining program for cutting to the side surface 22a and performing precision finishing is output (step S14).

  This output process is a process of storing the machining program as a second program file in a predetermined temporary storage area of the main storage device 14. Following the above, the machining programs are rearranged (step S15).

  This process is a process in which the first and second program files output as described above are read from a predetermined temporary storage area of the main storage device 14 and rearranged by the NC program sorting unit 123.

  That is, since the processing program of the second program file output using the local processing / manufacturing information 22b is a processing method used for a part to be subjected to precise processing, in this processing, the processing program is output using the entire manufacturing information. Rearrangement is performed so as to follow the machining program of the first program file.

  Next, the rearranged machining programs are combined by the NC program combining unit 124 (step S16). This process is a process of combining the two machining programs (first program file and second program file) that have been rearranged into one machining program (one program file).

  Note that, depending on the machining program creation method, the NC main program indicating the order of a plurality of programs is output without combining the NC programs. At this time, the first and second programs are treated as NC programs.

  Then, the combined machining program is output by the NC program output unit 125 (step S17). This output process is a process for outputting the machining programs combined as described above to the program memory area of the automatic machine tool, and is the same process as in the conventional CAM system. Further, the data may be output and stored in a predetermined storage area of the main storage device 14 instead of the program memory of the automatic machine tool.

  By configuring the CAD / CAM system as described above, it is possible to create a machining program that has been performed using a plurality of three-dimensional shapes so far as a skilled machining engineer has performed. It becomes possible to create easily.

  According to the above-described embodiment of the present invention, the overall manufacturing information for processing the entire shape including the machining allowance and the local manufacturing information for performing the local machining on the machining allowance portion (three-dimensional design shape). (Local processing manufacturing information) can be easily added, so that the number of work steps can be greatly reduced as compared with the conventional method using manufacturing information of two three-dimensional design shapes.

  In addition, this invention is not limited to the said embodiment, In the implementation stage, it can change variously in the range which does not change the summary.
