Application new algorithm and Matlab program for calculating the error of circle from co-ordinating data collected by Mitutoyo CMM C544

Based on the algorithm represented by P.B.Dhanish, authors kept applying and developing this algirithm to determine the error of circle from co-ordinating data collected by Mitutoyo CMM C544 machine. Data processing programme then was built. Finally, resulting research was applied to measure cylinder and hole parts.
