Thermal Deformation Measures for Machine Tools

Abstract

Thermal deformation of the machine tool has become important problem to improvethe machining accuracies. In order to solve such problems, many temperature control methods and reduction methods of thermal displacement have been developed to improve them. In this paper, the temperature variation of the model column covered various thermal insulating materials were measured by controlling room temperature change. From these results and computer simulations, the effects ofthermal insulating materials under ambient temperature changes were clarified.
