In recent days, high speed machining process is widely used to achieve efficient fabrication process for dies, mold and other mechanical parts. However, modern CNC controllers have problems with dynamic performance which have a great impact on accuracy and productivity. In the high-speed machining process, some factors such as jerk, acceleration, synchronizing of axis and small segment approximates the contours curve, could be a trigger of a break on feed-rate. Therefore, these problems make it difficult to predict instantaneous cutting force in actual manufacturing process.
In this paper, we proposed new feed-rate prediction model in high speed machining process. The proposed model can consider influences of CNC interpolation in the small segment approximation. The simulation results show the proposed model can predict dynamic performance of feed-rate in the high-speed machining process.
