One of the factors affecting the accuracy of Coordinate Measuring Systems is hysteresis of a probe head. It is important especially in case of touch trigger probes and should be taken into account during the determination of probing strategy. In this article, the authors try to assess how this phenomenon affects the accuracy of five axis coordinate systems which utilize articulating probe head. Such systems allow to measure point coordinates using rotary movements of the head what introduces changes to the probing process. The experiments presented in this paper are based on multiple measurements of the reference elements such as gauge blocks and standard ring.
