Abstract
A controller () for a machine tool () for tapping by a main shaft and a feed shaft, comprising an identifier unit () for identifying an index of the size of the tap, a temperature detector unit () for detecting the temperature of a motor () for the main shaft, an acceleration storage unit () for storing the acceleration of the main shaft corresponding to the index of the size of the tap, a rate storage unit () for storing the rate of varying the acceleration of the main shaft depending upon the temperature of the motor, and an acceleration calculation unit () for calculating a new acceleration of the main shaft by multiplying an acceleration determined from the index of the size of the tap and from the acceleration storage unit by a rate determined from the detected temperature and from the rate storage unit.
