The Effects of Machine Tool Pallet Change on Machine Tool Geometric Measurement Using the Scale and Master Ball Artefact Method (SAMBA)

The scale and master ball artefact (SAMBA) method is an indirect method for machine tool geometric error and volumetric errors estimation. It includes the hardware such as the master ball artefacts, scale bar artefact and touch trigger probe and the software based on the homogeneous transfer matrix. The hardware parts are often installed and removed from the machine tool pallet when implementing the SAMBA measurement. In this research, the experimental method has been used to discuss the effect of machine tool pallet change on SAMBA results. The results reveal that machine tool pallet change brings negligible changes on the SAMBA estimation results. However, the thermal states of machine tool appear to have a more significant effect on the final estimation of SAMBA method.
