Effect of ambient temperature on machine tool compensation functions

Abstract Volumetric verification is increasing daily its relevance. However, as it based on mathematical compensation, does not model only the influence of machine tool’s geometric error to verify, but total data. Among all sources, thermal variations due changes in environmental conditions strongly affect MT position accuracy. This paper studies how compensation functions a modification tool kinematic and generator synthetic It takes into consideration measurement noise too. Moreover, also differences between working accuracy functions. To do that, brief explanation developed algorithm presented.
