Abstract

PURPOSE:To average the degree of working the whole workpiece, by reducing vector quantity displaced by one time to the possible minimum and carrying out vector movement in each direction by a plurality of times. CONSTITUTION:After obtaining coordinates of the respective terminal points of relative displacement vectors, (n) coordinates per one vector are obtained by dividing equally said coordinate into (n) parts. Thus, the coordinate (X1, Y1) of the last terminal point of vector (a) is represented by formulas (1), (2), and the first terminal point (X11, Y11) of points obtained from equal division by (n) becomes (X1/n, Y1/n). However, when an electrode moves in each vector, the surface of the electrode in the vector direction of the first working has the most amount of working subject to the same machining allowance, resulting in presenting problems. Hence, the final value of vector shall be increased every one vector instead of varying it every one round.
