<p>PROBLEM TO BE SOLVED: To obtain uniform working accuracy by keeping the same cutting direction as the cutting direction before forming a mirror image to a work no matter which axis the mirror image is formed on. SOLUTION: Calculated target position coordinate values Xo and Yo are outputted in a stage 85, a state for not performing a mirror image function is indicated when a mirror image mode is '0' in the stage 80 and thus, a commanded cutting direction and an original cutting direction match. Then, the case that the mirror image mode is '1' is the case that the mirror image is formed only for one of an X axis and a Y axis and the mirror image function is performed only for one axis in the stage 86. Since the target positions Xo and Yo obtained in such a manner are provided with the same cutting direction as an original shape, they are stored along with interpolation information in a memory in the stage 87. Then, the operations are continued until a mirror image cancellation instruction sentence is commanded.</p> |
