Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides NC processing of each workpiece from parts drawing data and material drawing data by CAD (computer-aided design) or the like.
CAM of the production system that automatically creates data and -41 (
In the process of creating machining information to support computer-aided manufacturing, the order of tools or priority instructions for each tool are considered in advance for each part or work surface in order to determine the machining order by interacting with graphic information. The present invention relates to a machining order setting device for an automatic processing machine that sets the machining order while also taking into account the usage conditions of the tool itself and provides the flexibility and practicality necessary for an FMS (Flexible Manufacturing System).

[Conventional technology]

In the FMS, the computer operates the schedule plan, 9 machining setup plans, tool supply plan, etc. online, but the parts drawing data and material drawing data corresponding to the higher level are presented and downloaded to the FMS. Currently, the structure of the processing information creation device for processing information is inconsistent, and only partial and fragmentary structures exist.

Furthermore, CAD/CAM, which is applied to parts drawings and material drawings, can only be executed on a single part using a specific machine and a processing order based on a fixed process. Therefore, the cutting technology could not freely respond to various changes in the production system.

[Problem 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. Conventional CAD/CAM processes these two diagrams in a short-circuit manner, and can only be used when the machining conditions of the workpiece are specified, but needless to say, the machining work can be completed with a simple process. Rather than a simple transition, it is achieved through multiple processes under various conditions and constraints, including machines, jigs, combinations of workpieces, tools, etc. In particular, in FMS, it is necessary to consider drawings such as the mounting situation of the workpiece, jig and jig base conditions, and tool interference that arise from the constantly changing production plan, and this also involves changing the machining order. The results of the study will be greatly influenced by what is prioritized as a decision criterion. 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.

Also, when processing multiple workpieces on a table,
When there is a change in the production plan, the machining surface changes depending on the combination of workpieces, and the machining order 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 described above, even if the processing order of the workpieces 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 view of these circumstances.
We provide a machining order setting device for automatic processing machines that reconsiders tools to prioritize workpiece shape, tool conditions, machining schedule, etc., and sets the machining order with the flexibility to accommodate all settings. The purpose is to

[Means for solving problems]

In the present invention, the means for solving the above-mentioned problems is to determine the machining order of tools from the setup diagram data based on a priority instruction such as priority for each part, priority for each machining surface, or priority for each earth tool. It is a machining order setting device for automatic processing machines, which includes a setup diagram data memory that stores setup diagrams and their machining contents and data on tools used, and a machining order standard data memory that stores base bar data that sets the machining order. Examining the machining method for each step instruction while interacting with the file, the tool specification standard data file that stores the codes of tools that are ranked in particular, and the part shape output from the setup diagram data. a priority extraction processing means for processing the selected machining method according to a machining order standard and a tool specification standard, and a machining order determining means for determining the order in which the tools are used;
A processing order setting device for an automatic processing machine is characterized in that it includes a central processing unit that controls each means.

The above-mentioned setup drawing data includes material drawings and 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, this data can be displayed on a CRT
When output on the screen, the three-dimensional perspective view will look like the one shown in Figure 3, where multiple parts are arranged side by side, parts (te), jigs (j
), jig base (B), 119. It is a link between the coordinate systems of the machine (M), etc.

[Effect]

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 processing, machining order processing was performed by customizing tools 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, as shown in Fig. 4 (a), only part A is given priority. This is a method in which after processing Al-A2-A3, the process moves on to processing B parts.

In the same case, as shown in Fig. 4(b), if A part and B part are divided into four planes of 90 degrees each using a common machined plane, then the 0 degree plane -90 This is a method in which both parts A and B are completely machined on the -180 degree plane and -270 degree plane, and then transferred.

Priority for each tool applies to general processing machine systems, but even in cases like Figure 3, machining using common tools such as rough machining and finishing machining is prioritized as shown in Figure 4 (C). niA
This is a method in which parts and B parts are machined continuously with the same tool and then transferred to the next tool.

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 subordinate to the shape coordinate system, the shape coordinate system is the machined surface coordinate system, and the machined surface coordinate system is subordinated to the part coordinate system, and each coordinate system is subservient to the part coordinate system and is related to each other by having transformation data.

The machining order setting device embodying the present invention has the above machining information.
The present invention relates to the priority instruction processing section 38 and the tool-by-tool machining order processing section 39 in the production apparatus, but is not necessarily limited thereto.

In FIG. 1, the machining order setting device includes a central processing unit (CPLI) 1 which is a control unit for the entire device, a keyboard with a screen 2 which is an interactive means and its input/output device 2a, and reference data for setting the machining order. a machining order standard data file 3a that stores the machining order standard data file 3a, a tool specification standard data file 3b that stores the codes of tools whose rankings are specifically specified, setup plan data, part of the work file 2 data, and standard data.

a processing section 37 that takes in jig data and tool data and performs setup/alignment; a priority instruction processing section 38 that links this processed data with the 11 instructions for parts, machining surfaces, and tools inputted from the keyboard; It is roughly composed of a setup diagram data memory 44 for storing data processed by light instructions, a priority extraction processing means 64, and a processing order determining means 65. Machining tool processing unit 66 and its setting data memory 67 and post-processing tool processing unit 68 and its setting data memo 11
6, a priority instruction selection section 8G, and a pre-processing and post-processing data selection section 87 are connected. The internal configurations of the priority extraction processing means 6.1 and the processing order determining means 65 will be explained together with their operating procedures.

FIG. 5 is a flowchart showing the main points of the operation procedure of the above processing order setting device. In Fig. 5, when the machining order setting operation is started, first, as stage 0 (reading machining order standard data), machining order standard data as shown in the table below is read from the standard data file 3 (Fig. 2). , is stored in the processing order standard data file 3a in FIG.

Table 1 (Machining rank standard data) In the above table, the machining method codes are FM (face mill), SM (shell mill), EM (end mill),...
There are I (L (hole), TP (tap), etc., and the finishing level is rough (=10), semi-finished (=20), and finished (=30).
, top finishing (=40), precision finishing (-50), etc., and specify the maximum and minimum values, and similarly specify the maximum and minimum values for the tool diameter. Furthermore, the processing type group is also specified based on the processing content. The 11th order of this table data becomes the machining order for each tool.

Subsequently, as stage 0 (reading of tool code designation standard data), 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 2 (Tool code specification standard data) The above table specifies the group names in the data in Table 1 and the required tool codes in correspondence, and according to this table data, instructions are given in the order of the end of each group. A process will be performed to collect the tool codes.

The reading of the 0th stage and the 0th stage is usually reading from a floppy disk etc. into the memories 3a and 3b, but the reading of the priority instruction data of the 0th stage (reading of priority instruction data) is usually as follows. The operator uses the keyboard 2 to send the priority instruction processing unit 3 via the central processing unit 1.
8. The priority instruction data includes the priority order for each part, each machining surface, and each tool, as well as the tool symbol name of each pre-processing and post-processing tool, and the order of internal processing and post-processing is automatically determined. In this case, problems may arise in terms of machining technology, such as maintaining precision or tool damage. (For example, if the machining order for machining in which two holes are perpendicular to each other as shown in Fig. 6 is automatically determined, HL-B
L (rough machining) may be followed by HL-DL (light machining). In this order, machining HL and DL will bend and cause damage to the drill, so in this case, after machining HL-DL, HL and B
You will have to manually input the command to process L. ) Therefore, the pre-processing and post-processing are entered manually, and the automatic processing will be between the pre-processing and the rear machining.

The 0th stage (reading ACM data) is the reading of setup diagram data as CAM data, and the 0th stage Er-
When the operator manually issues a start command in step a, the setup diagram data as shown in FIG. 3 is inputted to the priority extraction processing means 64 from the setup diagram data memory 44 in FIG. The information is read into the extraction processing unit 70, 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,
The input data counter 72 is incremented by one for each accumulation.

Table 3 (input data) Here, the priority instruction selection unit 86 extracts the priority included in the setup diagram data (whether the command data is priority for each part, priority for each machining session, or priority for each tool). , is given to the priority extraction processing means 64 together with the input data via the gate.
Examination processing is performed for each of the stages 5a + 5b + and 5c while referring to the graphic output.

When the priority command for each component is input, the AND gate 102
The input data is sent to the component muscle input data processing section 7 through
3, and the data for each part code in the table above is edited in the parts can input data memory 74. When the priority command for each machining session is input, the input data is input to the manual data processing unit 75 for each machining session via the AND gate 103, and the data for each machining surface code in the table above is input data for each machining surface. - Edited in memory 76. If a tool priority command is input that corresponds to stage 0 of the procedure diagram (OR determination of the machining order for each tool for each part OR machining surface), the input data has already been edited for each tool, so the AND gate is applied as is. 1
04, and the OR gate 105 sends either the component can input data, the input data for each machining time, or this human power data to the next stage machining order determining means 65,
Processing up to stage 0 of the procedure diagram is performed.

The processing order determining means 65 is provided with two input gates, the first AND gate 10G receives the set signal from the input data counter 72, and the second AND gate 107 receives the end signal. A signal is input. The counter 72 is incremented every time the input data is accumulated, and is downcounted every time the cent signal is output.
When the count reaches zero, an end signal is output. Then, on the machining order determining means 65 side, input data for each part, each machining surface, or each tool is sent to the machining method code selection processing unit 7 from the AND game 1-106 for each manual effort of the CEF signal.
7 and apply the processing order determination standard data in Table 1 to assign a temporary processing order. For example, the data in Table 3 is assigned as in Table 4.

Table 4 (input data given machining order) 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, comparing Table 3 with Table 1,
The FM in order 1 in Table 3 has a finish level of 10 and a tool diameter of 100, which corresponds to the FM in order 1 of the standard data in Table 1.
Since the finish level does not correspond to the one with rank 99, it is output as rank 1, and since the tool diameter of 100 corresponds to both, it is output as rank 1 and rank 99. However, and gate 10
Since 8 is on the output side, only the output with rank 1 is approved. Similarly, in Table 3, the FM in order 2 has a finish level of 20 and becomes rank 99, the TP in order 3 passes the TP in rank 6, and the HL in order 4 has a finish level of 15 in rank 5 and rank 7.
Since the tool diameter of 79.5 corresponds to rank 7 and rank 98, the AND of both results in rank 7. HL in order 5 is ranked 9B due to the finish level of 30 and tool diameter of 80. Then, these and the ranking data Q of Table 4 stored in the selection criteria data memory 80 are combined with the AND gate 108.
The items that are satisfied are sequentially accumulated in the ranking memory 81, and a set request signal is sent to the counter 72 for each accumulation to activate the set signal. When all the input data have 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 unit 82, and the tool code designation criteria in Table 2 are input. Based on the data, it is organized into groups. However, for tools that have been designated for pre-machining or post-machining, the next stage machining order ascending processing unit 8
3, performs processing in ascending or descending order, outputs machining order determination data as shown in Table 5, and stores it in the machining order determination memory 8.
Save to 4.

Table 5 (Processing Order Determination Data) In the above table, output data orders 1 and 2 are in ascending order according to the pre-processing settings, and orders 8 and 9 are in descending order according to the post-processing settings. The present invention is not limited to the embodiment shown as a block diagram in FIG. 1, but even software-based processing is included within the technical idea of the present invention.

〔Effect of the invention〕

As explained above, according to the present invention, while considering the machining surface of the part and the tool conditions, etc., what to give priority to in the machining order is divided into three cases, and the input data processing is re-manipulated. It is possible to provide a processing order setting device for an automatic processing machine that maintains flexibility for changes between the three cases and automatically prepares a processing order that can accommodate all settings.
