Description

[Detailed description of the invention]

[Industrial Application Field] The present invention automatically creates NC data for each workpiece from parts drawing data and material drawing data using CAD (computer-aided design), etc., and creates a consistent production system using CMA (computer-aided manufacturing). In the process of creating machining information to support The present invention relates to a processing order setting device for an automatic processing machine that sets the processing order while taking conditions into account and provides the flexibility and practicality necessary for an FMS (Flexible Manufacturing System). [Conventional technology] In an FMS, a computer operates schedule plans, machining, setup plans, tool supply plans, etc. online, and from the presentation of higher-level parts drawing data and material drawing data to the FMS. Regarding the structure of the downloaded processing information creation device, there is currently a lack of consistency;
Only partial and fragmentary things existed. Also, CAD/
CAM could only be performed on a single part using a specific machine and a fixed process sequence. Therefore, the cutting technology could not freely respond to various changes in the production system. [Problems to be solved by the invention] The above material drawing data shows the shape and dimensions of the workpiece material before processing, and the parts drawing data shows the completed shape and dimensions of the part at the end of processing. In other words, the transition from the former to the latter is the process of processing information. Traditional CAD/CAM is
Only the one that treated these two figures in a short-circuit manner and specified the machining conditions of the workpiece could be used, but
Needless to say, processing work is not a simple transition that can be completed in one step, but involves machines, jigs,
It is achieved through multiple processes under various conditions and constraints such as combinations of workpieces and tools.
In particular, in FMS, it is necessary to consider the mounting situation of the workpiece, the conditions of the jig and jig base, the interference of tools, etc. that arise from the constantly changing production plan, and the machining order. The results of the study will be greatly influenced by what is prioritized as the setting criteria. That is, even when processing the same workpiece, the processing order of parts changes when the machine used for processing changes, or when the jig or jig base changes.
Furthermore, when processing a plurality of workpieces combined on a table, when a change in the production plan occurs, the processing surface changes depending on the combination of the workpieces, and the processing order also changes accordingly. Furthermore, in the case of a machine with an extremely wide machining area, such as a five-sided machining machine, the machining order is determined based on the tool. As mentioned above, even if the machining order of the workpiece changes each time, it is extremely important to fully consider each order and be able to accommodate all settings in order to improve the flexibility of the FMS. The present invention was developed in light of these circumstances, and has the flexibility to accommodate all settings by repeatedly examining tools to prioritize workpiece shape, tool conditions, machining schedule, etc. It is an object of the present invention to provide a processing order setting device for an automatic processing machine that sets the processing order using the following methods. [Means for Solving the Problems] In the present invention, the means for solving the above problems is to set priority instructions for each part, each machining surface, or each tool from the setup diagram data. It is a machining order setting device for automatic processing machines that determines the machining order of tools based on the data, and includes a setup diagram data memory that stores setup diagrams, their machining contents, and data on the tools used, and standard data that sets the machining order. Processing a machining order standard data file to be stored, a tool designation standard data file storing codes of tools whose orders are specifically specified, and setup diagram data in accordance with specified priority instructions,
a priority extraction processing means for extracting data on the machining contents and tools used for each tool; and data on the machining contents and tools used for each tool, which are preferentially extracted by the priority extraction processing means, according to the machining order standard and tool specification standard. A machining order setting device for an automatic processing machine is characterized in that it comprises a machining order determining means for processing and determining a machining order, and a central processing unit for controlling each means. The above setup drawing data includes material drawings, process drawings,
This data is created by calling jig bases, jig parts, etc., and combining multiple setup plans arranged for each workpiece and each process to edit the graphic information for the entire process.
For example, if you output this to a CRT screen, the three-dimensional perspective view will look like the one shown in Figure 3, where multiple parts are placed side by side and the coordinate systems of the parts, jig J, jig base B, machine M, etc. are linked. It becomes what it is. [Operation] As a result of analyzing the problem of what should be prioritized as a criterion for determining the machining order, we focused on the fact that processing can be done using one of three priority criteria: priority for each part, priority for each machined surface, and priority for each tool. After performing priority instruction processing, machining order processing was performed based on the tool characteristics based on the file. For example, when two parts A and B are combined as setup diagram data as shown in Fig. 3, giving priority to each part first means that only part A is prioritized from A1 to A1 as shown in Fig. 4a. This is a method in which after machining A2 → A3, the process moves on to machining part B. Giving priority to the machining surface means that in the same case, if parts A and B are divided by a common machining surface into four planes of 90 degrees each, as shown in Fig. 4b,
This is a method in which both parts A and B are completely machined on each surface in the order of 0 degree surface → 90 degree surface → 180 degree surface → 270 degree surface and then transferred. Giving priority to each tool is common to processing machine systems in general, but even in the case shown in Figure 3, machining using a common tool such as rough machining and finishing machining is performed on part A as shown in Figure 4 C. This refers to a method in which parts B and B are machined continuously with the same tool and then transferred to the next tool. [Example] Hereinafter, an example of the present invention will be described in detail based on the drawings. FIG. 1 is a block diagram showing an example of a processing order setting device in an automatic processing machine embodying the present invention. Since the machining order setting device is suitable for use as a part of a machining information creation device as shown in FIG. 2, the machining information creation device in general will be described first with reference to FIG. The present invention is broadly divided into four processing sections. The first processing department 101 is called machining design processing.
Input data on parts drawings and material drawings created with CAD, process drawings for CAM, material drawings, area drawings, process drawings, etc.
Create setup plan data. Second processing department 10
Step 2 is called machining method processing, in which process drawings and setup plan data are input, machining method settings, tool settings, tool integration, tool searches are performed, and the data is output as a machining standard document. Third processing department 103
This is called setup drawing processing, and uses the setup plan obtained from the machining design processing, material drawing data, and data obtained from the processing method processing to combine multiple machining parts in stages, arrange jig parts, and use tools. Performs an interference check and creates setup diagram data. The fourth processing department 104 is called machining technology processing, and determines the machining order, machining area, machining conditions, and cutting conditions based on the setup diagram data, and outputs the data as a work instruction. And the data obtained is
It is converted into a part program by processing data conversion processing. Next, NC data is created from the part program using an automatic NC data creation device. In Figure 2, various processing data and commands are sent to the CPU 1 from the input/output device 2 from the screen keyboard 2.
It is input and output via a. The drawing data input from the CAD device M is of two types: part drawing data Ma designed as a product and material drawing data Mb of the part to be processed, and shape data, additional data, etc. are input for each. As will be explained in each stage, the reference data file 3 stores various reference data that serve as a reference when processing is performed in each processing section. Machine data file 4 contains machine data such as the machine name and specifications of the machine to be installed, jig data file 5 contains jig data for mounting and fixing the workpiece, and tool data file 6 contains data to be used. Tool data such as tool name and tool diameter, and cutting condition standard data file 7 contains cutting condition standard data for determining cutting conditions. Based on the parts drawing data Ma and material drawing data Mb created by the CAD device M, it is converted into data that can be processed as CAM data. Processing drawing data, material drawing data, area drawing data, process drawing data, and setup plan data are created and processed (these processing steps are called processing design). The parts diagram data is taken into a parts diagram coordinate system setting processing section 8, and the coordinate system of the parts diagram is set. Four coordinate systems are set as the coordinate system of the part diagram: a part coordinate system, a processing surface coordinate system, a shape coordinate system, and a cross-sectional coordinate system. The cross-sectional coordinate system is dependent on the shape coordinate system, the shape coordinate system is dependent on the machining surface coordinate system, and the machining surface coordinate system is dependent on the component coordinate system, and these coordinate systems are dependent on the component coordinate system and are related to each other by having transformation data. Linked. Based on the four coordinate systems set in the parts drawing coordinate system setting processing section 8, the machining shape processing section 9 aggregates the machining shape into face machining, groove machining, side machining, pocket machining, hole machining, and stepped hole machining. The shape is then classified. Machining shape data processed based on various coordinate systems is stored in the memory 18 and output as machining drawing data. The material drawing data is taken into the material drawing coordinate system setting processing section 10, and the coordinate system of the material drawing is set.
Coordinate system settings for material drawings are similar to those for parts drawings. Based on the coordinate system set by the material drawing coordinate system setting processing section 10, the material shape processing section 11 classifies the material shape into surfaces, grooves, side surfaces, pockets, holes, and stepped holes and stores them as material drawing data. 19 and output. The machining drawing data and material drawing data are taken into a machining area drawing processing section 12 that synthesizes them. By combining the machining drawing data and the material drawing data, a region to be cut away is created. Furthermore, in the area diagram correction processing unit 13, the polishing amount G/
Area correction processing such as W or precision finishing allowance is performed, and processing area map data is stored in the memory 20 and output. Each area map data is processed by processing area division processing unit 1.

This is a process in which the arrangement or method of mounting and fixing is changed (setup change) during machining), or in other words, when rough, medium, and finishing machining is performed by dividing into multiple processes. The machining area is divided, the divided data and the machine data in the machine data file 4 are imported into the process drawing processing unit 15, which instructs the machine to be used, and performs setup (installation of parts on pallets) in the specified machine. Machining shapes that can be automatically machined in one step (fixing work) are collected, process drawing data is created, and the data is stored in the memory 21. The process drawing data, material drawing data, and jig data are taken into the setup plan processing unit 16, and as shown in FIG. _A ), processing for arranging jig parts J (stoppers, clamping plates, bolts, etc.) is performed. Furthermore, the tool interference check processing section 17 displays and moves the machine origin and tool to perform an interference check and check the proper placement of parts W _A and jig J in one process, as well as the data of each shape and each coordinate system. Obtain the transformed data to be concatenated. The setup plan data is stored in the memory 22 and output.

When one part is completed, the next part diagram is processed. Processing design processing is performed by performing the above procedure for each part and for each process. Next, processing of the machining method described in detail below is performed based on each data and reference data stored in the machining design file 59 described above. Necessary data filed in the machining design file 59 and necessary reference data filed in the reference data file 3 are taken into the area processing unit 23 for each machining method, and the six types of machining methods (surface, surface,

The area data for each tool includes roughing, finishing, or roughing/finishing.

The area data for each tool is taken into the per-tool machining content processing section 26 along with necessary standard data, and the machining diameter, machining depth, etc. for each tool code (face mill cutter, end mill cutter, etc.) is processed to create machining content data for each tool. is stored in the memory 33 and output. The reference data is setting data such as tool diameter and tool length for each tool. Machining content data for each tool and necessary standard data are taken into the integrated instruction processing section 27 and processed and created so as to integrate and instruct common areas, for example, common areas that can be cut with the same tool, from each tool area. , integrated instruction data are stored in the memory 34 and output. Standard data such as machinable depth is prepared in a memory table for each tool code.
In addition, the tool diameter and tool width ranges are set for roughing, medium, and finishing machining.

Processing is done. The created tool data is stored in the tool data memory 35.

The machining standard creation processing unit 29 generates a machining standard that displays a list of machining details such as tool diameter, finish level, and machining surface for each tool, and the machining standard output data is stored in the memory 36. Output. The output data stored in these memories 30 to 36 are stored in work files 2 and 55 one by one for each process of one part. When processing for each process is performed and processing standard data for the part is created, a part-by-part end signal opens the gate 58, and each data stored in the work files 2 and 55 is filed in the processing method file 60. Ru. When the processing for each process of one part is completed, the data of the next part is input from the CAD device M, and the data of the next part is inputted to the first processing department 10.
The processes of the first and second processing departments 102 are repeated. Next, based on the machining design file 59 and the machining method file 60, setup diagram processing and machining procedure processing, which will be described in detail below, are performed. Setup plan data filed in the machining design file 59, necessary standard data filed in the standard data file 3, jig data filed in the jig data file 5, and tool data filed in the tool data file 6. The tool data and each data filed in the machining method file 60 are taken into the stage combination processing unit 37, and based on the connection of each coordinate system, the combination of setups by arranging a plurality of parts and the arrangement of jig parts are performed. Then, processing is performed to perform a tool interference check. Further, the priority instruction processing section 38 prioritizes parts, machining surfaces, and tools, performs processing to control the machining order based on the priority instructions, and stores the setup diagram data in the memory 44 and outputs it.

and the tool-by-tool machining order processing section 39, but are not necessarily limited thereto. In FIG. 1, the processing order setting device includes a central processing unit (CPU) 1 which is a control section of the entire device;
A keyboard with a screen 2 and its input/output device 2a as a means of interaction, a machining order standard data file 3a that stores standard data for setting the machining order, and tool specification standard data that stores codes of tools whose rankings are specifically specified.・File 3b, setup plan data, part of work file 2 data, and standard data,

The main bus of the central processing unit 1 further includes a pre-machining tool processing section 66 and its setting data memory 67, which will be described later.
and the post-processing tool processing section 68 and its setting data.
The memory 69, the priority instruction selection section 86, and the pre-processing/post-processing data selection section 87 are connected. The internal configurations of the priority extraction processing means 64 and the processing order determining means 65 will be explained together with their operating procedures. FIG. 5 is a procedure diagram showing an outline of the operation procedure of the above-mentioned processing order setting device. In FIG. 5, when the machining order setting operation is started, the machining order standard data as shown in the table below is first transferred to the standard data file 3 as the step (reading of machining order standard data).
(FIG. 2) and stored in the processing order standard data file 3a shown in FIG.

[Table] In the table above, the processing method codes include FM (face mill), SM (shell mill), EM (end mill),...HL (hole), TP (tap), etc., and the finishing level is rough (=10). , semi-finishing (=20), finishing (=30), top finishing (=40), precision finishing (=50), etc., and specify the maximum and minimum values, and the tool diameter also indicates the maximum and minimum values. In addition, the machining type group is also specified based on the machining content.Then, the order of this table data becomes the machining order for each tool.Subsequently, as the first stage (reading the tool code specification standard data) , the tool code designation standard data as shown in the table below is read and stored in the tool designation standard data file 3b shown in FIG.

[Table] The table above specifies the group names in Table 1 data in correspondence with the required tool codes. According to this table data, the specified tool codes are specified in the last order of each group. A collection process will be performed. The reading in the above-mentioned stages is usually reading from a floppy disk or the like into the memories 3a and 3b, but the reading of the priority instruction data in the first stage (reading the priority instruction data) is as follows.
Normally, the operator gives the priority instruction processing unit 38 via the central processing unit 1 using the keyboard 2. Priority instruction data is for each part, each machining surface,
There is a priority order for each tool and a tool symbol name for each pre-processing and post-processing tool.
If the processing order of pre-processing and post-processing is automatically determined, problems may occur in terms of machining technology, such as maintaining accuracy or damage to tools. (For example, if the machining order for machining where two holes are orthogonal as shown in Figure 6 is automatically determined, first HL/BL (rough machining), then
It may be HL/DL (light processing). In this order, machining HL and DL will bend and cause damage to the drill, so in this case, you will have to manually enter the machining of HL and BL after machining HL and DL. ) Therefore, the pre-processing and post-processing are entered manually, and the automatic processing will be between the pre-processing and post-processing. The stage (reading ACM data) is to read the setup diagram data as CAM data.When the operator inputs a start command at the end of the stage, the setup diagram data as shown in Fig. 3 is read.
The priority extraction processing means 6 is routed from the setup diagram data memory 44 in FIG. 1 via the AND gate 101.
The data is read into the input data extraction processing section 70 of No. 4, and the machining content data for each tool, data on the tools used, etc. are extracted as input data as shown in the table below. The extracted input data is accumulated in the input data memory 71 line by line, and the input data counter 72 is incremented by one for each accumulation.

[Table] Here, the priority instruction selection unit 86 extracts whether the priority command data included in the setup diagram data is priority for each part, priority for each machining surface, or priority for each tool.
It is given to the priority extraction processing means 64 together with input data via a gate. 5th stage 5a, 5 respectively
Examination processing will be performed for b and 5c while referring to the graphic output. When the priority command for each component is input, the input data is inputted to the input data processing unit for each component 73 via the AND gate 102, and the data for each component code in the above table is stored in the input data memory for each component 74. Edited. When the priority command for each machining surface is input, the input data is inputted to the per-machining surface input data processing section 75 via the AND gate 103, and the data for each machining surface code in the table above becomes the input data for each machining surface.
Edited in memory 76. If this is a tool priority command that corresponds to the first stage of the procedure diagram (determining the machining order for each tool for each part OR machining surface), the input data is already edited for each tool, so it is sent directly to the AND gate 104. The OR gate 105 sends input data for each part, input data for each machining surface, or this input data to the next stage machining order determining means 65, and processes up to the first stage in the procedure diagram. will be held. The processing order determining means 65 is provided with two input gates, the first AND gate 106
A set signal is input from the input data counter 72 to the second AND gate 107, and an end signal is input to the second AND gate 107. The counter 72 counts up each time input data is accumulated, and counts down each time a set signal is output, and outputs an end signal when the count reaches zero. and,
On the machining order determining means 65 side, input data for each part, each machining surface, or each tool is input from the AND game 106 to the machining method code selection processing section 77 for each input of the set signal, and the machining method shown in Table 1 is performed. A temporary processing order is assigned by applying the order determination standard data. For example, the data in Table 3 is assigned as in Table 4.

[Table] The same input data is also input to the finish level comparison processing section 78 and the tool diameter comparison processing section 79. For example, Table 3 is compared with Table 1, and the FM of order 1 is
The finish level of 10 and tool diameter of 100 correspond to rank 1 of the FM in the standard data in Table 1, and the finish level does not correspond to rank 99, so it is output as rank 1, and tool diameter of 100 is output for both. Since it is applicable, it will be output as rank 1 and rank 99. However, since the AND gate 108 is on the output side, only the output of rank 1 is approved. Similarly, the FM with rank 2 in Table 3 becomes rank 99 due to the finish level of 20, and the FM with rank 3 has a finishing level of 20.
The TP passes the TP with rank 6, and the finish level 15 of HL in order 4 corresponds to ranks 5 and 7, and the tool diameter of 79.5 corresponds to ranks 7 and 98, so the AND of the two results in rank 7. HL in order 5 has a finish level of 30
And the tool diameter is 80, so it is ranked 98. Then, these and the ranking data Q of Table 4 stored in the selection criteria data memory 80 are combined with the AND gate 1.
Rank memory 81 sequentially from those satisfied in 08
are accumulated, and a set request signal is sent to the counter 72 for each accumulation, thereby activating the set signal. When all the input data has completed the above processing, the end signal is input to the AND gate 107, so the data in the ranking memory 81 is input to the tool designation processing section 82, and the tool code designation standard data in Table 2 is input. are organized into groups based on. However, for tools that have been designated for pre-machining or post-machining, the machining order ascending order processing unit 83 in the next stage performs processing in ascending or descending order, and outputs machining order determination data as shown in Table 5. and stores it in the machining order determination memory 84.

〔Effect of the invention〕

As explained above, according to the present invention, what is prioritized regarding the machining order is determined by taking into account the machining surface of the part, tool conditions, etc., and repeating the processing of input data in three cases.
It is possible to provide a processing order setting device for an automatic processing machine that maintains flexibility for changes between two cases and automatically prepares a processing order that can accommodate all settings.
