Abstract
A controller including: a positional deviation calculating unit that calculates positional deviation using a position command directed to a servo motor for driving a cutting tool, etc., and a position feedback value corresponding to the position of the cutting tool, etc.; an oscillation command calculating unit that calculates an oscillation command using the position command and a spindle axis angle of the rotated work, etc., or using the position feedback value and the spindle axis angle; an oscillation offset calculating unit that calculates an offset for the oscillation command using the positional deviation, the oscillation command, and the spindle axis angle; and a driving unit that determines a drive signal for the servo motor based on the positional deviation, the oscillation command, and the oscillation offset, and outputs the drive signal.
