Abstract—Computer numerical control (CNC) machine tools operated at high speeds and under high-acceleration machining conditions with discontinuous tool paths cause undesirable vibrations because of the rigidity of the mechanical structure and abrupt changes in the feed rates. Therefore, this study develops a feed rate determination method for tool path interpolation to determine proper feed rates at the junctions of adjacent piece-wise continued machining segments. This method helps limit over-cutting, feed acceleration, and feed jerk values at junctions. Experiments conducted on a three-axis CNC milling machine using a tool path with different corner angles successfully validated the executing performance and feasibility of the approaches developed in this study.
