Abstract
With the development of manufacturing towards complex workpieces with narrow tolerances, it has brought coordinate measurement systems (CMS) to a leading position in the verification processes. There are a number of different CMS used today that are characterized by sampling mode, accuracy, speed, flexibility. Many CMS do not have established procedures for verifying accuracy. This paper aimed to determine the accuracy of different CMS on the example of measuring the standards of flatness with known calibration values. The results showed high performance coordinate measuring machines for both probe and poor performance for industrial CT.
