Abstract
A new cutting force simulator which calculates discretely uncut chip thickness by referring workpiece voxel model has been developed to predict cutting force in end-milling operation. This cutting force simulator can predict cutting force under the complex change of workpiece shape and the non-uniform contact between cutting edge and workpiece. Additionally, a new methodology to realize adaptive control or feed speed control based on the predicted cutting force is developed by integrating with the digital copy milling system which can generate tool paths in real-time during machining operation. This methodology can revise the tool feed speed based on the cutting force which predicted simultaneously with the real end-milling operation
