An indirect technique for the correction of thermo-elastic displacements induced by loads of the linear axes is developed in subproject B06. The basis is formed by an control-internal correction approach describing the functional relationship between the mechanical load profile and the displacement of the Tool Center Point using transfer functions of different orders. The model parameters referred to are determined in displacement experiments. Since axes load-induced displacements highly depend on the position, a volumetric measurement and correction approach is utilised.
