MODELING AND COMPENSATION
TECHNIQUE FOR THE GEOMETRIC
ERRORS OF FIVE-AXIS CNC
MACHINE TOOLS*
Abstract:
One of the important trends in precision machining is the development of real-time error compensation technique. The error compensation for multi-axis CNC machine tools is very difficult and attractive. The modeling for the geometric error of five-axis CNC
machine tools based on multi-body systems is proposed. And the
key technique of the compensation—identifying geometric error parameters—is developed. The simulation of cutting workpiece to verify the modeling based on the multi-body systems is also considered.
