NUMERICAL CONTROL DEVICE FOR A GRINDING MACHINE |
摘要 |
A numerical control device for a grinding machine is equipped with a servo-motor which moves at least one of a spindle and a dresser. The spindle and/or the dresser moves relative to the dresser shaft center direction and the rotor shaft center direction. The numerical control device compensates an amount of servo lag using a target position compensation calculating circuit. A unit time target position is obtained by performing a track calculation at unit times on the basis of the amount of servo lag stored in a storage device. Feedback control of the servo motor is effected by calculating a compensated target position dependent on the unit time target position.
