Abstract
The measurement system of dynamic accuracy of a multi-axis machine tool was developed in this research. This system is constructed with measuring parts using liner-scale which resolution is less than 0.1 micrometer and ceramics air slide and data analysis unit. Dynamic accuracy measurement was performed about the circle locus and straight-line locus in a simultaneous 5-axis control state, and this research has estimated the processing locus. In this report, dynamic accuracy adapting the technique of space positioning was measured, and the technique of evaluating the locus accuracy of a machine tool was developed.
