Measurement and analysis of friction fluctuations in linear guideways

This paper addresses the analysis of friction fluctuations in linear guideways, which influence positional deviations of machine tool drives. Several measurement experiments evaluate the influence of contact conditions and ball circulation conditions, and fluctuations in the measured friction forces for several guideways were compared. The amplitude spectra for motion wavelengths clarified the reduction of friction fluctuations for different experimental parameters. (C) 2018 Published by Elsevier Ltd on behalf of CIRP.
