机床的控制装置
摘要：
本发明涉及一种机床的控制装置，预先存储根据加工程序使上述机床动作时的该机床的热位移在饱和状态下的热位移状态(目标热位移状态)，决定电动机的预热运行动作模式，使得接近该目标热位移状态。按照预热运行动作模式驱动电动机，当机床的热位移状态在预定的范围内时，停止该电动机的预热运行。
摘要（英）：

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.
