(B) Next, the operator pushes a drawing button (not shown) on the CRT 7 to display a planing diagram, for example, as shown in FIG. 5, corresponding to the entire machining program on the CRT 7. When this plan view is displayed, all punches are
Decomposes without a single shot in the relationship shown in.

(C) Next, the operator designates a frame (designation of start point and end point) one or more times to limit the machining range in the machining program by designating a frame on the plan drawing as shown in FIG. 7, for example. This is done by changing the background color of the shaded area. At this time, cursor movement keys to up, down, left, right, extraction key,
Use the delete key, other keys, etc. to set the start and end points of the frame. Further, when a plurality of frames are designated and the range limitation is confirmed, the outside of the limitation range is erased as shown in FIG.

(D) Next, the operator presses the mold list display button to display the mounted mold data as shown in FIG. 9 on the CRT.
7 Display on top.

(E) Next, the operator limits the mold with the cursor up / down cursor keys, the extraction key, other keys, etc., and displays the limited portions in different colors according to the relationship shown in FIG. 10, for example. Make it easy to understand. Even within the range limited by (C) above, blocks using these molds are deleted and not processed.

(F) At the time when the mold is limited by the above operation (E), the CRT is used for treatment with the limited mold.
7 is displayed, for example, as shown in FIG. 11, and the operator confirms the processed portion from this display state. After confirmation, for example, pressing the execution key starts the processing.

With the flow of the operations shown in FIGS. 3A to 3F, the respective processes shown in FIG. 2 are sequentially performed to process an arbitrary portion in the machining program. Therefore, according to the present embodiment, it is possible to arbitrarily select the machining range in the machining program without knowledge of the machining program.

The trouble of can be avoided.

Further, after the machining range of the machining program is appropriately selected by designating a frame on the plan drawing using the plan drawing corresponding to the entire machining program, the entire designated portion is offset (moved). By sequentially interpreting and executing each block of the machining program, for example, a program with repositioning is prepared in advance without repositioning as shown in FIG. 12 due to the limitation of the size of the material sheet. This is convenient when it is desired to perform processing in two steps, a range X1 for processing with a material and a range X2 for processing with another material.

Further, the machining range of the machining program is appropriately selected by designating the frame on the planing diagram using the planing diagram corresponding to the entire machining program, and the machining range X3 is selected as shown in FIG. 13 (A). After setting, the machining range X4 different from the machining range X3 can be machined into another machining program (additional program) as shown in FIG.
The usability of the C machine can be improved.

[0037]

As described above, according to the present invention,
By changing the processing program to a single-shot reorganization processing program and displaying it graphically, by using both the range specification by the frame and the mold selection, the processing range can be specified arbitrarily. When the user wants to process only a part of the program, it is possible to instruct and process an arbitrary range in the processing program by pictorial editing without understanding the program statement.
