Machine Tool Thermal Deviations Caused By
Linear Axis Motion

Abstract
It has been proposed a simple six-degree-of-freedom measurement method of thermal
deviations caused by linear axis motion that has compatibility with the method
in IS0230-3. In this study, the measurement tests were carried out on two machining
centres that have their own different structures. From the results, it was made
clear that the thermal deviations are large not only in the feed direction, but also in
the other direction; and these deviations and thermal deformation modes depend
largely on the type of machine structure.
1 Introduction
Thermal deviation of machine tools has become a serious problem in recent years.
A universal measurement and evaluation method for the deviation should be expected.
With this point as the background, the international standard IS0 230-3 was
established in May 2001. I
