1. INTRODUCTION Five-axis CNC machine tools are becoming increasingly more popular because of their ability to machine geometrically complex workpieces efficiently and with higher dimensional accuracy. This is due to the machine's ability to take full advantage of conventional tool geometry by controlling the orientation of the cutting edge. For a three-axis CNC machine tool, geometric errors are usually measured and identified quickly according to the well-established methods, including ISO 10,791 and ISO 230. For a multi-axis CNC machine tool, the identification of geometric errors is quite difficult due to the presence of rotary axis .
