Because the demand of multi-axis controlled machine tool is increasing recently, the new interface functions for the machine tool are needed, which allow us the institutive, safe and accurate operation. The final purpose of our research is development of interface which operates a multi-axis controlled machine tool directly by Haptic Device. However, in the developed interface, operator's tremor disturbed tool path, and disorder of tool path deteriorated the appearance of machined surface. This report introduces the interface function that reduces disorder of tool path by approximating tool path as sets of curves and straight lines. The most difficult part in the approximation is the determination of segmentation point. In this research, segmentation points are determined by corner points of tool path and speed at the tip of device. As the result, we confirmed the decrease in disorder of tool path and the improvement of appearance of machined surface.
