This paper presents an useful technique for error assessment of CMM with simple gauges such as step gauge. A computer module for measurement path generation is implemented,where the appropriate measurement sequences are generated in terms of DMIS file format for CMMs of CNC mode. After the CNC codes are downloaded into CMMs, the measurement operations are performed, and the error analysis are followed. Positional errors, angular errors are successfully measured with high precision along the 3 axis in relatively short time. The squareness error is also assessed with the step gauge measurement data. The developed system has been practically applied, and showed good performance.
