Then, in the NC program, the NC program code determination unit 13 determines whether or not a range (hereinafter, referred to as an attention range) SAR to be noticed for displaying the machining area or input guidance is designated by the attention range designation unit 12. (Step S1) If the attention range SAR is not designated, the NC program is saved and all the processes are terminated.

On the other hand, for example, as shown in FIG.
If AR is specified, the NC program code determination unit 13 determines whether or not there is a preparatory function code (hereinafter, referred to as G code) for declaring the shape specification of the turning fixed cycle within the attention range SAR. Judge (step S2),
If the G code exists, the attention range is expanded to the entire range of the designated shape called by the G code as shown in FIG. 4 (step S3). Then, the machining area shape designated by the expanded attention range or information SIF of the machining shape is used as a turning fixed cycle machining area information output unit 15.
It is output to the display screen generation unit 113 via (step S4). When the entire range of the specified shape called by the specified G code is not fixed, the NC program being edited is extended to the end. Further, the NC program code determination unit 13 determines whether or not the block being edited exists anywhere in the machining shape designation portion in the attention range SAR (step S5), and the attention range S
If there is no block being edited in AR, step S
If the block being edited exists, the process proceeds to step 11 to highlight the shape element indicated by the block being edited with respect to the machining area shape or machining shape information SIF output from the turning fixed cycle machining area information output unit 15. The in-editing block highlighting designation unit 14 designates to add (step S6).

On the other hand, in step S2, the range of interest S
If the G code declaring the shape designation of the turning fixed cycle does not exist in the AR, the NC program code judgment unit 13 judges whether or not the G code indicating the operation of the tool cutting edge exists in the attention range SAR. (Step S7), if the G code does not exist, the process proceeds to step S11. If the G code exists, the information SIT of the cutting edge motion shape within the attention range SAR is displayed on the display screen via the tool cutting edge motion shape information output unit 16.
