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. In the process of creating machining information to support CAM (computer-aided manufacturing), each region map data is created by combining the shape data of machining drawings and material drawings, and through interactive processing with figure output and automatic processing, each The present invention relates to a machining process processing device in an automatic processing machine that creates a process diagram for each machining process.

[Conventional technology]

In an FMS, a computer operates schedule plans, machining, setup plans, tool supply plans, etc. online, and creates machining information to be downloaded to the FMS by presenting parts drawing data and material drawing data corresponding to the higher level. Regarding the structure of the device, there is currently a lack of consistency;
Only partial and fragmentary things exist;
CAD/CAM, which is applied to parts drawings and material drawings, can only be executed on a single part using a specific machine in a fixed processing order. Therefore,
The cutting technology was not able to respond freely to various changes in the production system.

[Problem that the invention seeks to solve]

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, so to speak, it is a transition from the former to the latter. is the processing work. Conventional CAD/CAM processes these two diagrams in a short-circuit manner, and only the workpiece is supported, but needless to say, the machining work is not a simple transition that can be completed in one step, but rather requires the use of tools. This is achieved through multiple processes under various initial conditions and constraints, and the best one must be selected from among various possibilities when creating machining areas and dividing processes. This work was left to the laborious desk work of groping by hand.

The present invention was developed in view of these circumstances, and further divides area map data in which machining areas are registered for each part from the viewpoint of machining accuracy and setup changes, allowing for detailed examination and quick disposal. It is an object of the present invention to provide a processing device for an automatic processing machine that allows flexibility obtained through selection and repetition thereof, and leveling of the production process.

[Means for solving problems]

In the present invention, the means for solving the above-mentioned problems is to set a machining area in the figure data of parts drawings and material drawings, and extract the required area from area diagram data synthesized by interactive operation and automatic processing. It is a machining process processing device in an automatic processing machine that creates a process diagram using a process diagram, and includes a machining area division processing unit that specifies division of a machining area, and an area extraction/deletion unit that selects each divided machining area from a desired viewpoint. A setting unit group, a process diagram extraction processing unit that registers the extracted area together with control information such as machine name and process name, and a process diagram that returns a desired area from the registered process diagram data to unprocessed area information. A machining process processing device for an automatic processing machine is characterized by comprising a deletion processing section and a process diagram data memory for temporarily holding process diagram data.

In the above apparatus, the area diagram data can be displayed by restricting the content of the drawing by items such as the component coordinate system, the processing surface coordinate system, the type of shape, and the shape coordinate system. The desired viewpoint for selecting the divided processing areas is which item of the area map data should be used for selection.

In this specification, extraction refers to creating part or all of the area map data into process chart data.
Deletion means returning part or all of the process drawing data to area drawing data.

[Effect]

A region diagram in the database is input, a process number is given, and the necessary region is extracted (registered) through interactive operations and automatic processing, and is made into one process.

In order to easily register areas, functions such as area display, area extraction, area deletion, and process number correction are provided.

The basic method is to specify and extract the displayed area, but it is also possible to input or specify the machined surface, machined surface coordinate system, shape type, and attributes of the displayed area (rough, medium, or finished), which will be described later. This allows for batch extraction. The area after extraction becomes inactive (does not react even when manipulated).

By deleting an area that has already been registered as a process diagram, it is possible to return it to the remaining area information (active state). As with drawing and displaying, it is possible to restrict and delete items such as the part coordinate system (overall), machined surface coordinate system, shape type, and shape coordinate system.

The area information before extraction is drawn and displayed in "display", and the completed process diagram is drawn and displayed in "reference display". The former allows modification, division, etc., but the latter allows only display.

Consists of 6.

FIG. 3 is a procedural diagram showing the operating procedure of the above device. Below, while comparing Figures 1 and 3,
The operation of the above device will be explained.

In the first step of the procedure, a region map is input. The parts drawing data Ma indicates the finished state of the part, and when this is output on the screen, the shape and dimensions of the part are shown in a vertical cross-sectional view and a plan view, as shown in Figure 4 A, and whether or not the part has been processed is shown. is the cutting mark ▽
Or it is marked with a black skin mark. For example, in FIG. 4A, surface machining A and B on the upper and lower surfaces and stepped hole machining C on the center portion are instructed. Such parts diagram data Ma is input to the parts diagram coordinate system setting processing unit 8, and the parts coordinate system (X ₀₁ ,
The _machining diagram data shown in _FIG . On the other hand, material drawing data
Mb indicates the condition of the raw material of the workpiece, and when this is output on the screen, the shape and dimensions of the material are shown in a longitudinal cross-sectional view and a plan view, as shown in Figure 5 A, and for example, the amount of machining on the upper and lower surfaces. A' and B' and the central opening C' are
mm) is added. Material drawing data like this
After inputting Mb to the material drawing coordinate system setting processing section 10 and setting the material coordinate system (x ₀₂ , y ₀₂ , z ₀₂ ), the material shape processing section 11 extracts material shapes A', B', and C'. This is the material drawing data shown in Figure 5B.

When the data in Fig. 4B and Fig. 5B are input from the respective data memories 18 and 19 to the machining area diagram processing unit 12 and displayed on the screen, the part coordinate system and the material coordinate system can be arbitrarily determined. Since these have been set, they will not be superimposed on the screen as is, but will instead be displayed as shown in FIG. 6B, for example. The operator converts the material coordinates by operating the stylus pen 2c or the like so that the same parts of the parts are overlapped on the screen. Although this operation can be performed by converting any coordinate system, it is usually easier to use the component coordinate system as the core. The area map data shown in FIG. 6A is obtained by superimposing the processed drawing and the material drawing so that the material display data (double-dashed line in the figure) D that is common to both data coincides with each other. The area map data is stored in data memory 20. However, as is clear from a simple examination, this area map data includes machining A on the top surface and machining B on the bottom surface, and cannot be machined without changing the setup. Therefore, it is necessary to divide the area into at least the area shown in FIG. 7A and the area shown in FIG. 7B and process them in separate processes.
The device of the present invention processes this. In addition,
The area map correction processing unit 13 performs area correction processing such as polishing or precision finishing allowance.

The first step is to input the process number. Enter the number of the process (process number) that you want to extract and register. Furthermore, after the area extraction is completed, the process number can be modified so that it can be treated as a processing sequence number. Also, enter the name of the machine to be used.

The first stage of the procedure is to transfer the above area map data from the area map data memory 20 to the processing area division processing unit 14.
call and command the division.

The area information can be displayed by restricting the drawing content using items such as the part coordinate system (overall), the machined surface coordinate system, the type of shape, and the shape coordinate system. In addition, after displaying, it is possible to enlarge, reduce, and move, making it easy to do this even in areas where the width is narrow and it is difficult to indicate, such as intermediate and finishing areas.

In the first stage of the procedure, one of the four extraction commands, division extraction, machining surface extraction, machining surface coordinate system extraction, and shape type extraction, is applied to the divided region in the corresponding setting section 81, 82, 83, 84. is divided into predetermined areas.

Divided extraction is a method of extracting regions based on the attributes of the region (rough machining, semi-machining, finishing machining).

Machining surface extraction is a method of extracting regions based on the machining directions for the four surfaces of the pallet, as shown in FIG. 8A.

The processing surface coordinate system extraction is as shown in Figure 8B.
Even if the machined surface has the same angle θ° with respect to the pallet P, depending on the shape of the workpiece W, there may be multiple
For example, two machining plane coordinate systems A ₁ and A ₂ may be set, and an area is extracted for each coordinate system symbol A ₁ or A ₂ given to them.

Shape type extraction is a method of extracting regions for each type of shape, since the machined shape is classified into six shape types as shown in the tree in FIG. 8C.

The first stage of the procedure is region registration, and the OR gate 101 inputs the regions extracted from any of the above extraction setting sections to the process drawing extraction processing section 87, where they are sorted according to the respective extraction methods. The above-mentioned machine name and process number are assigned using the keyboard and registered in the process drawing data. At this time, desired control information can be added as the first step of the procedure. For example, station numbers and various equipment names in the FMS line etc. are registered as reference information.

The registered process drawing data is stored in the process drawing data memory 21, and when all areas of the area drawing data memory 20 are transferred, the extraction work is completed, but the area for each process is If the diagram data is extremely unbalanced, processing efficiency is poor and it is necessary to consider region division again. That is, it is possible to arbitrarily return the area in the process drawing data memory 21 to the area drawing data memory 20, and this is called a deletion operation.

The deletion work is performed by giving one of the four deletion commands: processing surface coordinate system deletion, shape type deletion, component coordinate system deletion, and shape coordinate system deletion to the respective corresponding setting units 83, 84, 85, and 86. It will be done.

Processing surface coordinate system deletion and shape type deletion are performed using the same criteria as explained in the extraction section.

If it is desired to redone all the data, the deletion setting can be applied to the entire area by issuing a command to delete the component coordinate system and giving it to the component coordinate system deletion setting unit 85.

Shape coordinate system deletion is a method of dividing and deleting an area according to a coordinate system that is further subdivided and set for each type of shape.

The area set for deletion by any of the above deletion setting units is deregistered by the process drawing deletion processing unit 88 via the OR gate 102, and returned to the area drawing data memory 20.

Note that the machining surface coordinate system extraction/deletion setting section 83 and the shape type extraction/deletion setting section 84 serve both for extraction and deletion, so commands are input via the OR gates 103 and 104, and the area diagram data or process diagram Data is or gate 105 or 106
Input via . In addition, the manual adjustment section 89 receives a manual adjustment command to set the processing surface coordinate system, the extraction/deletion setting section 83 , the shape type extraction/deletion setting section 84 , the component coordinate system deletion setting section 85 , and the shape coordinate system deletion setting section 86 . You can give commands to either of them and perform partial deletion based on the command.

FIG. 9 is an explanatory diagram showing an example of extraction and deletion.
Solid lines indicate active regions and dashed lines indicate inactive regions. First, extract the upper left part of the diagram and assign a process number, then extract the right half and assign a process number, and finally extract the lower left part and assign a process number to create process diagram data. Suppose we did. However, as a result of the study, if there are too many machining operations in the second process, for example, there are problems with the machining time or the number of tools, then the right half will be returned from the process diagram to the area diagram by deletion, and a different extraction method will be used again. etc., only the lower right portion is extracted and a process number is assigned, and the remaining upper right portion is extracted and a process number is assigned. Furthermore, if the process number is different from the processing order and is inconvenient, it is possible to re-sort and re-assign the process name. The above-mentioned apparatus repeats such extraction and deletion to arrive at the best region division and process creation.

As described above, the processing processing device according to the present invention can proceed from a rough examination to a detailed examination through dialogue and repeated processing for extracting and deleting areas, and furthermore, the extraction and deletion are automated and quick according to the method. In addition, it is possible to recognize the machining shape of each part with the tool in mind and distribute it to each process, aiming for balance, flexibility, and leveling of the production process. You can draw and display the remaining area information in "Display" and the extracted process diagram in "Reference display" when necessary, making it easy to create extremely difficult process diagrams after careful consideration. .

Physically separate processes due to cutting direction restrictions,
After temporarily dividing something that needs to be divided into roughing or finishing processes due to problems with machining accuracy, detailed examination becomes possible by repeatedly using functions such as area deletion and area extraction.

By modifying the process number, you can work without worrying about the actual processing order of each process.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to achieve the best area division and process creation by providing detailed consideration, quick selection, and flexibility obtained by repeating these processes, and the production process It is possible to provide a machining process processing device for an automatic processing machine that contributes to leveling of the process.
