PURPOSE:To perform the automatic generation of an NC program by storing graphic element data in sequence of continuity, and designating a working start point and a working direction. CONSTITUTION:A graphic is inputted to a display according to a working drawing by using an input device, and also, the graphic data of each graphic element is filed in an external memory device 4. Next, each graphic element is arranged in sequence of continuity as a graphic A, and is stored in the external memory device 4. After that, an operator magnifies or reduces the graphic A in an arbitrary offset quantity (f) (clearance quantity) at need. Following that, the operator designates a part to be worked first. Thereby, two start points (difference of clearance) being positioned inside and outside the graphic A are displayed on the bisector of the graphic element and in the neighborhood of the said graphic element. Either two points is selected, then, working is started. |
