PURPOSE:To make it possible to make the copy motion in the direction of no particular angle of practical use by repeating the process to adjust the copying angle by the compensation angles in proportion to the difference amount determined by comparing the actual machine position with ideal copy locus. CONSTITUTION:A copying speed controlling section 14 loops with a stylus three (3) axes displacement signal 13 and a copying speed command signal 15 controlling three (3) axes of a machine with a stylus 11 copying a model 12. And the copying speed controlling section 14 determines the distance DELTAd between machine positions and ideal copy locus strait lines by using the copying angles input and the machine position integrated value signals of X and Y axes. A compensation angle DELTAphi is calculated by multiplying the difference amount DELTAd by gains and the distribution amount of the horizontal direction speed to X and Y axes is also calculated by adding DELTAphi to the copying angles to output the copying angle signal 15 to each of X axis servo system 25 and Y axis servo system 26. |
