This paper presents a stochastic method to approximate the thermal deformation of a machine tool, by using the temperature changes of the body. The method examines the relationship between the thermal deformations and temperature changes of plural positions on a machine tool, and determines the appropriate temperature measuring points. In addition, the approximate equation of the thermal deformation is drawn by t-test, which uses those influential temperature changes as parameters. This study shows that the approximation equation of the thermal deformations can be expressed in a simple form with few parameters, and remarkably improve cutting processing.
