<p>Cycle machining can be easily performed in a good precision by controlling machines for machining a prototype and other products. The operator inputs graphic data such as of circular and rectangular figures through a keyboard or the like conversationally in accordance with the guidance appearing on a display (16). Graphic data storage means (1) stores the graphic data thus inputted. Transformation means (2) calculates the machining paths which are required for the cycle machining, and transforms the graphic data into NC instructions. NC instruction storage means (3) stores the NC instructions. Interpolation means (4) outputs interpolating pulse signals for moving tools along the machining paths of the cycle machining according to the pulse signals output from a manual pulse generator and jog feed buttons on a machine operation board (40). Thus, it is possible for the operator to execute a cycle machining easily and exactly while confirming the machining condition by operating the machine operation board (40). <IMAGE></p> |
