An analysis of influence of sampling strategy and scanning speed on estimation of straightness and flatness deviations with CMMs

Krzysztof Stępień


The paper deals with the problem of influence of scanning speed and measuring strategy on results of flatness and straightness deviations with CMMs. The straightness was studied for various numbers of sampling points and for various scanning speeds. The flatness was investigated for various measurement paths and for various levels of scanning speeds. The results of the study indicate that applied measurement speed and selected measurement path can change obtained results very significantly.
