PURPOSE:To control main work and back-surface work at a same time by inserting a back-surface working program and a back-surface work starting code into a working program for operating an NC apparatus. CONSTITUTION:The control part 31 of an NC apparatus 30 transmits the back- surface working program stored into a main memory part 32 and inserted into a working program into a back-surface working memory part 34 by reading the transmission starting code, and memorizes the back-surface working program. Then, main work is started by reading the main working program. When the back-surface working starting code is read, the back-surface working program is further read, and a servomotor 18 is controlled by a sequence controller 33 through a position controlling unit 35 and a driver 36 independently of the control for the main work by the NC controller 30, and back-surface work is carried-out in parallel with main work. Therefore, the main work and the back-surface work can be controlled at a same time by a 3-axis or 2-axis NC apparatus. |
