Abstract
In recent years, a demand of the high quality cutting surface of press die represented by a car is increased for shortening of polishing time. Cutting surface quality is strongly affected by tool path quality, and disturbance of NC data causes deterioration of cutting surface. However, it is difficult to judge tool path quality in advance and evaluation method becomes a problem. Various methods have been proposed in the past. The conventional method is to calculate and visualize the disturbance of NC data. However, with the conventional method, it is difficult to accurately analyze the influence on the cutting surface quality. Therefore, we have proposed a method of quantifying the quality of the tool path based on the information of the cutting conditions and the desired cutting surface quality. In this paper, report investigation of the method which quantify of tool path and predict of cutting surface condition to realize high quality cutting surface before cutting.
