Abstract

PURPOSE:To avoid the need of a control shaft for a tool by previously inputting the revolution ratio of tool shaft/main spindle into an NC device and feeding the detection value of the main spindle revolution speed directly into a tool shaft controller in working and automatically determining the revolution speed of the tool shaft by a polygon controller. CONSTITUTION:Before working, the polygon ratio of the revolution speed of tool axis/main spindle and the main spindle revolution speed are inputted into an NC device 11, and the polygon ratio is given into a polygon controller 15 from the device 11. The main spindle revolution speed is given into a main spindle control part 12 from the device 11, and the revolution speed of a main spindle motor 4 is determined so as to correspond to the main spindle revolution speed. In order to keep the determined speed constant, a speed feedback mechanism (d) is constituted from the control part 12, motor 4, and an encoder 16. Further, after the revolution speed of the main spindle 3 is detected by a pulse coder 17 and sent into the control part 12, said revolution speed is sent directly into the polygon controller 15, and the revolution speed of a tool shaft 9 is determined on the basis of the main spindle revolution speed and the polygon ratio, and the revolution speed of a motor 10 for a rotary tool shaft is determined in a rotary tool control part 14, and revolution is carried out. The controller 15 controls the revolution speed of the tool shaft according to the polygon ratio.
