Abstract: PURPOSE:To cancel synchronous errors by adding a synchronous correction amount obtained from detected rotational speed multiplied by thread magnification to a commanding position of a feed shaft to provide a temporary commanding position so that feed is controlled by speed corresponding to the deviation of detected position from said commanding position. CONSTITUTION:A spindle motor 3 is rotatably driven with set rotational speed thetaV and the rotational angle thereof is detected by a detector 4 to be sent to the input of a constant multiplier 5 and multiplied by thread multiplication KV so that a true commanding position theta of a feed shaft is given to a position adder 11. Also, the actual rotational speed thetaV of spindle motor 3 is detected by a detector 12 and multiplied by the thread magnification KV with a synchronous deviation amount calculator 10 to obtain a synchronous correction amount  theta which is added to the true commanding position theta by a position added 11 to provide a temporary commanding position thetaC. The deviation (e) of position thetaC from a feed shaft position P detected by a detector 9 is obtained by a synchronous deviation calculator 6 to drive a feed servo motor 8 through a servo pump 7 with speed proportional to said deviation. Thus, synchronous errors are eliminated and the spindle and feed shaft can be run in synchronization with each other with high accuracy.
