In this study, in order to apply the zigzag path to high-speed milling, the curing condition was examine. Moreover, the comparison experiment of cutter locations generated from the developed CAM and the commercial CAM was done, and following results were obtained. 1. In high-speed milling by zigzag path, the cutting force decreases because of slowing down of the feed speed at the direction change part. 2. The decrease in machining accuracy by the transient overshoot, which occurs during abrupt acceleration and deceleration in frequent direction change at a short time, can be controlled by the feed speed moderation at the direction change part on the NC data 3. The cutting force increases at tool entry of vertical and groove machining, and this is imminent to chipping of cutting edge. The cutting force at the tool entry can be controlled by decreasing the feed speed and by adopting the slant machining. 4. CAM software for the high-speed milling is developed, which can control the increase in cutting force and the dynamic impact by avoiding the long groove machining and by adapting the slant machining at the tool entry. 5. The rough cutting time by zigzag path could be reduced to half as much as conventional ones. Therefore, the effectiveness of the CAM was experimentally verified.
