Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention automatically creates NC data for production equipment and machinery for each workpiece from parts drawing data and material drawing data using CAD (computer-aided design), etc. CAM (computer-aided manufacturing) production system
Regarding a processing information setting device in an automatic processing machine that supports
Displays CAM data, links various coordinate systems related to setup work, and sets machining information in automatic processing machines that have flexibility and practicality suitable for FMS (Flexible Manufacturing System). Regarding equipment.

[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, has been limited to simply creating processing information for one part using a specific machine and using fixed setup operations. Therefore, there has not been a processing information setting device like FMS that can be flexibly handled in a production system where the production schedule changes drastically.

[Problem that the invention seeks to solve]

Machining information is not just the NC data necessary for automatic operation of NC machine tools. Deciding what kind of concept and what kind of machining method to use for machining a part is greatly reflected in the NC data that is created. The main purpose of current CAM is to automatically create processing information for parts placed on NC machine tools.
It has not yet reached the point where evaluation of production methods using FMS etc. is considered. On the other hand, CAD parts drawing data and material drawing data are simply processing information that determines the final result. It is necessary to include information on machining techniques, such as determining process procedures (determining process steps, etc.), machining methods, and arranging, combining, and fixing parts on pallets in an optimal manner, so-called setup methods, etc.

The problem here is, first, how to divide the machining process and decide which machines to use in order to improve efficiency and level the production. Secondly, for the divided machining and fixing, there is a method of machining setup, such as how to arrange parts on pallets or combine them for machining. Thirdly, how to conceptualize the machining method, and based on the machining shape and machining accuracy information,
Considering the tools to be used and the process of allocating the machining area is the key to consistency and flexibility from CAD to NC machining.

The above parts drawing data shows the completed shape and dimensions of the part at the end of processing, and the material drawing data shows the shape and dimensions of the workpiece material before processing, so to speak, it is a transition from the latter to the former. is the processing work. Conventional CAD/CAM processes both of these diagrams in a short-circuit manner, and only the workpieces that are processed through specific setup operations are eligible for assistance.Needless to say, however, there is a transition in which machining operations can be completed in one simple process. Rather, it is achieved through multiple processes under the constraints of various conditions such as tools. In particular, in FMS, the mounting situation of the workpiece, the jig and jig-based conditions , tool interference, etc. need to be considered in the drawings, and it is extremely important to be able to consider them in any state during machining work to improve flexibility.

If the machining information is not consistent, it would be impossible, for example, to insert a temporary workpiece into the production system, and the FMS would naturally lose its flexibility and lack practicality. . Also, processing information at each point can be visualized specifically.
CAD/CAM also cannot be replaced with other parts or materials unless consistency is provided.

The present invention was developed in view of these circumstances, and provides consistency and flexibility that directly leads to the creation of NC data that can be used immediately for automatic production from part data, material data, and minimal setting data. Combined with
The purpose is to provide a consistent processing information setting device for automatic processing machines required for FMS, etc.

[Means for solving problems]

In the present invention, means for solving the above-mentioned problems include a figure information input means for inputting designed part drawing data and material drawing data of a workpiece as digital signals, and the input part drawing data and material drawing data. Part drawing coordinate system setting data and material drawing coordinate system setting data in which data is set in each coordinate system, jig part coordinate system setting data in which jig part data is set in the coordinate system, and jig base shape data. Using jig base coordinate system setting data set in that coordinate system and machine coordinate system setting data setting machine specification data in that coordinate system, parts, jig parts, jig bases, and machines in one process are Processing in an automatic processing machine equipped with a first processing unit group that sets setup plan data indicating layout, a second processing unit group that sets work instruction data, and a central processing unit that controls the progress of each process. In the information setting device, a material coordinate system conversion processing unit in which a first processing unit associates and superimposes the part drawing coordinate system setting data and material drawing coordinate system setting data, converts them, and imports them as material coordinate system conversion data; a component coordinate system conversion processing unit that associates and converts the part drawing coordinate system setting data with a jig base coordinate system and imports the data as component coordinate system conversion data; a jig component coordinate system conversion processing unit that converts the machine coordinate system setting data to a coordinate system based on a jig and imports the data as jig component coordinate system conversion data; The processing unit associates and transforms the component coordinate system transformation data and the jig component coordinate system transformation data all at once based on the jig-based coordinate system, and also correlates the machine coordinate system transformation data based on the jig-based coordinate system. A setup plan coordinate system conversion processing section that converts and imports the setup plan coordinate system conversion data as a whole, and the conversion data of each coordinate system conversion section are used to convert parts, jig parts, jig bases, and machines in one process. The present invention is a machining information setting device for an automatic processing machine, characterized by comprising a setup plan processing section that generates setup plan data indicating a layout by synthesizing figures for each coordinate system.

It is assumed that the reference data used in each of the above processes is prepared in advance as a file in a database, and each processed data is also temporarily stored in an online storage unit to be prepared for the next stage of processing.

[Effect]

Rather than simply transferring machining work from material drawing data to parts drawing data, conducting a comprehensive study that includes the machining center machine, jig, and jig base that will carry out the transfer will improve the setup. I will consider it. All the data used for this study is treated as graphic information and can be viewed visually on the display, but generally each has a different coordinate system, so by providing transformation data between each coordinate system and linking them, it is necessary to become manageable. In the present invention, various elements of a setup plan are simulated as graphic information,
By importing the data linking each coordinate system into file memory, comprehensive setup plan data is created, which is used as NC data in conjunction with the subsequent creation of processing standards and work instructions. This automatically sets processing information for processing.

FIG. 1 is a block diagram showing the first processing section 101 in FIG. 2 in more detail. In both figures, when parts drawing data is input from the CAD device M, the parts drawing coordinate system setting processing unit 8 sets the parts coordinate system (x ₀ , y ₀ , z ₀ ) and stores this data in the online memory. 8a, and using this data, the machining shape processing section 9 creates machining drawing data from the parts diagram data as shown in FIG. 3A. Figure 3B shows the contents of the machining drawing data.
It is a schematic diagram displayed in three dimensions on a CRT screen. Similarly, when material drawing data is input, the material drawing coordinate system setting processing section 10 sets the material drawing coordinate system (x _n , y _n ,
z _n ) and save the data to online memory 1.
0a, and based on the data, the material shape processing section 11 creates material drawing data from the material drawing data as shown in FIG. 4A. FIG. 4B is a schematic diagram in which the contents of the material drawing data are displayed three-dimensionally on a CRT screen. This machining drawing data and material drawing data are stored as is in the set coordinate system.
When superimposed on the CRT screen, the display is from the origin of each coordinate system, so it is displayed as shown in Figure 5A. To display this in relation to the actual material and parts (products), simply move the coordinates of the processing drawing data or material drawing data and overlap them at the position shown in Figure 5 B. However, in the material coordinate system conversion processing unit 71 in FIG. 1, the operator moves the figures while monitoring the CRT screen using the screen keyboard 2, and inputs a processing end signal when they are superimposed. Material coordinate system transformation data C _n that links the component coordinate system and material coordinate system specifies the relative position of the origin (x, y, z) and the relative angle of each axis (θ _x , θ _y , θ _z ) and stored in the online memory 71a. 1st

Now, as explained in FIG. 2, the first processing section 101 of the processing information creation device according to the present invention
In this method, the process drawing data, material drawing data, and jig data are finally input to the setup plan processing section 16 and tool interference check processing section 17 to create setup plan data. In order to process it graphically, it is necessary to link each coordinate system to each other.

Therefore, the operator first converts the figures of the process diagram data obtained by dividing the area diagram data shown in Figure 5 (B) by process into the figures of the jig base (B) data 73b shown in Figure 6 (B). are superimposed on the CRT screen as shown in Figure 7. This process is performed in the component coordinate system conversion processing unit 75, and after examining each setup plan, the jig base coordinate system (x _B , y _B , z _B ) input from the online memory 73c and the online memory The component coordinate system input from 8a (x _p , y _p ,
z _p ) _is captured for (x, y, z) and (θ _x , θ _y , θ _z ) and stored in the online memory 75a. Next, the figure of the jig part data 72b shown in FIG. 6A is added to the figure shown in FIG.
As shown in the figure, the jig component coordinate system conversion processing unit 76 converts the jig component coordinate system (x _J , y _J , z _J ) input from the online memory 72c and the jig base coordinate system (x _B , y _B , z _B ) _is captured for (x, y, z) and (θ _x , θ _y , θ _z ) and stored in the online memory 76a. Ru. Furthermore, the figure shown in FIG. 8 is converted into the machine data 7 shown in FIG.
4b (spindle head H, tool T, machine table T _A )
The machine coordinate system conversion processing unit 77 converts the machine coordinate system (x _M , y _M , z _M ) inputted from the online memory 74c and the jig base coordinate system ( x _B , y _B , z _B ), mechanical coordinate system transformation data _CM is captured for (x, y, z) and (θ _x , θ _y , θ _z ) and stored in the online memory 77a. .

The setup plan data linked in this way and synthesized on the CRT screen can be translated and rotated on the jig base B by creating conversion data for each setup plan. This process is performed by the setup plan coordinate conversion processing unit 78, and for example, moves the data on the jig base B from the state shown in FIG. 9 as indicated by arrow L, and changes it to the state shown in FIG. 10 on the CRT screen. When the process is performed and a key input is performed, the setup plan conversion data C _D for that setup plan is captured and stored in the online memory 78a. The operator performs an interference check on the setup plan using the tool interference check processing section 17, and saves the preferred setup plan as setup plan data in the file 22 to prepare for the next stage of processing.

As is clear from the above, each coordinate system of this embodiment has a hierarchical structure with the jig base coordinate system as the core, as shown in FIG. The jig base coordinate system Q _B is set, for example, at the center of the jig base when creating a setup plan, and is a coordinate system that serves as a reference for the placement of parts and jig parts _{. p} can be placed at an appropriate position on the jig base by creating conversion data indicating the relative position and relative axis angle from the jig base coordinate system Q _B for each setup plan. The machine coordinate system Q _M also specifies the origin of the machine as a relative position and angle from the jig base. When moving the component coordinate system, whether the material drawing or the process drawing is moved, both move. This is because the component coordinate system Q _p and the material coordinate system Q _n are linked.
