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 modeling 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.
