<p>This invention relates to a command system of a numerical control device (7a, 7b) that controls a complex machine tool (1a, 1b) in accordance with a machining program. It is constituted to switch between selections of diameter and radius of a coordinate value with a G code (9a, 9b) in the machining program (8a, 8b). Since the G code is made capable of switching the selections of diameter and radius, programming can be written using a specified value accommodated to a machining need of the machine tool. In addition, when machining programs separately prepared for diameter selection or semidiameter selection are combined, both the programs can be easily combined by specifying a G code, either for diameter selection or radius selection, at the head of a program.</p> |
