Abstract
Existing control methods for the thermal stability of machine tools are based on two fundamentally different principles: - changes in the position of objects of the impact; - change of the thermal state of the objects of the impact. It is substantiated and experimentally shown that the thermal spindle displacement for any machine design solution occur no more than three types of laws out of sixteen possible types of laws. A new concept and algorithm of an sensorless thermal controller for the spindle axis displacement is proposed.
