FIG. 1 is a block diagram showing a schematic configuration of an NC program editing apparatus according to the present invention, and a portion surrounded by an alternate long and short dash line represents a portion forming a man-machine interface.

A key input from the keyboard 200 is accepted by the key input management unit 10, synchronized with each part in the apparatus, and then sent to the program editing unit 20 and the tool path drawing data forming unit 40.

On the other hand, the program stored in the memory unit 300 of the NC unit is expanded in the work area of the RAM section 60, and this RAM 60 is referred to by the program editing section 20 and the tool path drawing data forming section 40. N
The memory unit program editing unit 20 of the C device is an editor, displays a program in code units, accepts a key input for editing, and performs editing such as insertion, deletion, movement, and copying of program contents at the position where the cursor exists. . Further, the tool path drawing data configuration unit 40 performs an operation necessary for displaying the tool path based on the information related to the tool path in the program contents developed in the work area.

The editing result of the program editing section 20 is configured as display data on the screen by the first display data configuration section 30. At this time, the program editing state is displayed in the program editing area 403 provided in the upper right part of the screen 401, as shown in FIG. When displaying in this area, a cursor 405 for editing is simultaneously displayed so that the program portion can be scanned.
