Thermo-mechanical finite element (FE) models predict the thermal behavior of machine tools and the associated mechanical deviations. However, one disadvantage is their high computational expense, linked to the evaluation of the large systems of diffe

A framework of methods for efficient and accurate simulation of the dynamics of machine tools including control is presented. The major achievements are a model order reduction technique with pre-definable error bound and a method for modelling of mo

Friction is a nonlinear phenomenon being present between moving components. For the axis of a machine tool, frictional and control effects have a strong influence on the system’s dynamic behavior. Due to their nonlinearity, frictional effects are u

Mechatronic structures deform under static and dynamic loads. These deformations lead to deviations at the tool center point (TCP), affecting the reachable accuracy and/or productivity of the machines. The scope of this work is the comparison of calc

This paper presents an effective method for the synchronisation of multiple feed axes with differing controller bandwidths by delaying the set point trajectories of those axes with higher bandwidths. First, a simplified model of a cascade-controlled

Accurate finite element machine modelling is typically connected with high computational costs. For this reason, machine structures are usually simplified or analysed only partially. In this paper, an efficient machine modelling technique is presente
