(Example) Hereinafter, the present invention will be described in detail using the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of a machining simulator according to an embodiment of the present invention.

As shown in the figure, the simulator has an equipment data input section 1, a processing condition input section 2, an equipment selection section 3, a processing process design section 4, and a layout design section 5 as input sections.

The design surface data input section 1 is connected to the equipment data storage section 1a. The equipment data input unit 1 is used to input equipment data such as a machining center, a lathe, an automatic guided vehicle, and an automatic self-weight that constitute the FMS in advance, and the input data is stored in the equipment data storage unit 1a.

The processing condition input section 2 is connected to the equipment selection section 3. The machining condition input section 2 is for inputting machining conditions such as the machining region and shape and dimensions of the workpiece (workpiece).

The equipment selection section 3 is connected to the processing condition input section 1, the processing process design section 4, and the equipment data storage section 1a. The equipment selection unit 3 is operated based on input operations from the processing condition input unit 2, and outputs candidates for the corresponding equipment to limit the data in the equipment data storage unit 1a. All operations of the equipment selection section 3 can be automatic, but may be performed manually as appropriate.

The machining process equipment section 4 is connected to the equipment selection section 3, the equipment data storage section 1a, and the layout design section 5, and is also connected to the machining process data storage section 4a. The machining process design unit 4 uses the equipment data determined by the equipment selection unit 3 and the machining process order constraint data in the machining process data storage unit 4a.
This determines the order of workpiece machining steps. The determined machining process order is stored in the machining process data storage section 4a.

The layout design section 5 is connected to the processing process design section 4, the process data storage section 4a, and the layout data storage section 5a. The layout design unit 5 reads equipment data from the equipment data storage unit 4a, for example, and converts it to CR.
A predetermined layout is created on the CRT by interacting with the operator, such as displaying the image at a designated position on the CRT. The layout result is stored in the layout data storage section 5a.

Note that the equipment selection section 3, the processing process design section 4, and the layout design section 5 may all be formed manually, semi-automatically, or fully automatically.

Due to the actions of each of the above members 1 to 5, the equipment data storage section 1
Equipment data to be used is stored in a, processing data is stored in a processing process data storage section 4a, and layout data is stored in a layout data storage section 5a.

The automatic programming section 6 includes each data storage section 1a, 4a.
, 5a. The automatic programming section 6 automatically creates a simulation program based on various input data.

The simulation execution section 7 is an automatic programming section 6.
It executes the program created in .

The simulation data output unit 8 has a CRT, a printer, etc., and outputs the simulation results.
It is something that

The operation of the simulator having the above configuration will be explained with reference to the flowchart of FIG.

In steps 202, 204, 206, 208, and 210, predetermined inputs are made from each input section 1.2.3, 4.5, respectively.

However, before these steps, decision block 201
．． 203.205.207.209 has been established,
Apart from the first simulation, only required inputs are performed from the second simulation onwards.

In step 202, equipment data is input, in step 204, processing conditions of the workpiece are input, in step 206, equipment selection is performed, in step 208, process design is performed, and in step 210, layout is performed. . In addition, in these steps, the input and the result are stored in a predetermined storage unit 1a, 4a, or 5a.

Step 206.208.210! 2! l! As mentioned above, some of the processes can be replaced automatically as appropriate.

In step 211, the automatic programming section 6 automatically creates a simulation program.

In step 212, the created simulation program is executed.

In step 213, the simulation data is CR
It is output to T or printer.

In step 214, the operator determines whether or not a satisfactory result has been obtained. If the result is satisfactory, the process ends here, and if unsatisfied, the process returns to step 201.

In steps 201 to 210, only the portions where the conditions are desired to be changed are changed according to the operator's wishes, and a new simulation is then performed under the changed conditions.

As described above, in this embodiment, the operator does not need to know the simulation-specific language, and each input section 1 to 5
By interacting with the user, the desired simulation can be easily and quickly performed.

Further, in this example, since a desired flow can be entered when changing conditions, processing for changing conditions such as changing modeling is easy.

Since a layout drawing can be created by the operation of the layout design section 5, the layout drawing can be obtained together with the simulation results.

This invention is not limited to the above embodiments, and may be implemented in other embodiments by making appropriate design changes.
