The paper presents the idea and need for the holistic modelling of machine tools. The complexity of such modelling is illustrated for a 5-axis machining centre. The need to model errors in the controllable axes of machine tools with rotational and linear motion drives is indicated. The physical dependences having a bearing on the state of deformations produced by temperature and dynamic forces, as well as the assumptions and computational modelsof shift generation in the high-speed bearing sets of spindles, and models of the behaviour of the ball screw are presented. Moreover, the results of experimental studies of the thermal behaviour of linear motor sets and guideways with rolling blocks are reported.
