Various methods of circular interpolation performance analysis

The paper discusses the possibilities and methodology of utilizing software, designed to be used with a double ball bar device analyze CNC machine tool positioning performance, measurements measured by different method. Renishaw Ballbar system is special allow rapid highly effective checks performance any numerically controlled cartesian structure, such as tool, at same time allows monitoring its condition some extent predict future development. uses sophisticated algorithms decompose overall inaccuracy examined values individual errors offers possible actions remove errors. ability push circularity, measurement circularity machined surface on coordinate measuring machine, would checking presence various without necessity measure device. Therefore, presents custom that shows possibilities, which was developed Department Automation Production Systems, Faculty Mechanical Engineering, University Zilina.
