Abstract

PURPOSE:To permit the high speed screw permit the with high accuracy by improving the following performance of the feed position for the revolution position by providing a means for calculating the feed instruction value on the basis of the screw pitch from the revolution deviation and allowing an feed motor to be synchronously driven. CONSTITUTION:A calculator 22 calculates a revolution instruction value S, and the deviation E(S)=S-(s) from the revolution position (s) of a main spindle 11 which is detected by a pulse generator 14 is calculated by a deviation counter 23, and inputted into a servoamplifier 24, together with the speed signal V(s) of a tachogenerator 13, and a rotary motor 12 is driven. The feed instruction value Z=E(S).P/L is calculated from the screw pitch P and the lead L of a ball screw 6 according to the revolution deviation E(S) by a calculator 25. The revolution quantity (s) of the pulse generator 14 is multiplied by P/L in a calculator 29, and the feed correction value r(s) is calculated, and the feed deviation E(z) is calculated from the above-described value and the pulse supplied from a pulse generator 9 by a deviation counter 29, and the feed instruction value Z is corrected by an adder 26, and the feed instruction value R(Z) is obtained and inputted into a servoamplifier 27, together with the speed signal V(z) of a tachogenerator 8, and a feed motor 7 is driven.
