Abstract

Summary The paper presents a new method of modelling thermal behaviour of a machine tool in service based on integrated determination of power losses in the kinematic system components, temperatures and thermal displacements. The method is applicable to any operational conditions. The mathematical model and its organization are presented. Basic features of the method are shown in a case study of a machining centre whose service thermal behaviour is analysed.
