摘要:
A thermal displacement state (target thermal displacement state) in which thermal displacement of a machine tool is saturated when the machine tool is operated based on a machining program is previously stored, and a warm-up operation pattern of a motor is determined so as to approach the target thermal displacement state. The motor is driven based on the warm-up operation pattern and the warm-up operation of the motor is stopped if the thermal displacement state of the machine tool is within a predetermined range.
