PURPOSE:To move wire reversely in working groove and in X-axis, Y-axis symmetrical paths by specifying reverse working command data from NC data under working and storing sequentially and upon completion of working, reading out said data in reverse order and specifying the path. CONSTITUTION:Data read out from NC tape 105 through a tape reader 104 is processed by a processor 102 to drive a pulse motor and to store the path data into a path memory 109 sequentially. After reading out end-of-work data from NC tape 105, data is read out in reverse order from the path memory 109 to drive the pulse motor reversely or in X-axis, Y-axis symmetrically on the basis of said data. Consequently data is not required to be formed for every path. |
