Modeling and Compensation Technique for Geometric Errors of Five-axis CNC Machine Tools

One of the important researching key points in machine tools techniques is the development of real-time error compensation technique, the error compensation for multi-axis CNC machine tools is very difficult but attractive. The mod- eling for the geometric error of five axis CNC machine tools based on multi-body systems was proposed in the paper, and the key technique of compensation-identifying geometric error parameters was developed. The process simulation of cutting workpiece to verify the modeling based on the multi-body system was researched for evaluating the results of modeling.
