Coordinate Measuring Machines (CMM) become one of the main requirements in precision engineering for advanced industries, troubleshooting and scientific facilities. CMM data analysis software can contribute significantly to the total measurement errors. The error characteristics in the CMM software are very important from the metrological point of view to find an optimum fitting solution. The final accuracy of a work piece is influenced by many different factors. In this paper, the fitting software methods and styles touch probe scanning speed factors for three different transverse circles of roundness measurement errors are studied experimentally and discussed in details. The tests have been performed to examine the problem of how to generate reference data sets for cylinder circle measurements. Some error formula have been postulated to correlate the roundness measurements within application range. These reference data sets are presented to help the CMM designer and operator to get the best fit for roundness measurements.
