Quality of coordinate measuring machine (CMM) in dimension and form metrology is designed and performed at the NIS.\nThe experimental investigation of CMM performance is developed by using reference Flick standard. The measurement errors\nof corresponding geometric evaluation algorithm (LSQ, ME, MC, and MI) and probe scanning speed (1, 2, 3, 4, and 5 mm/s)\nare obtained through repeated arrangement, comparison, and judgment. The experimental results show that the roundness error\ndeviation can be evaluated effectively and exactly for CMM performance by using Flick standard. Some of influencing quantities for\ndiameter and roundness for merrorsmay dominate the results at all fitting algorithms under certain circumstances. It can be shown\nthat the 2 mm/s probe speed gives smaller roundness error than 1, 3, 4, and 5 mm/s within 0.2 : 0.3 ????m. It ensures that measurement\nat 2 mm/s is the best case to satisfy the high level of accuracy in the certain condition. Using Flick standard as a quality evaluation\ntool noted a high precision incremental in diameter and roundness form indication. This means a better transfer stability of CMM\nquality could be significantly improved.Moreover, some error for mulae of data sets have been postulated to correlate the diameter\nand roundness measurements within the application range. Uncertainty resulting from CMM and environmental temperature has\nbeen evaluated and confirmed the quality degree of confidence in the proposed performance investigation.
