Article Preview

Thermal errors are important sources of positioning errors in precision machines and are more and more becoming determining factors to meet increasing specifications. In this paper, thermal modal analysis is used to study and reduce the transient thermal displacement errors in precision machines. The temperature decomposition and the thermal displacement field decomposition by thermal modal analysis are derived. The reduction of transient thermal errors by adding additional heat loads is analyzed and the results of two different methods are compared.
