It is known that the machined shape errors occurred in the NC machine tools can be compensated by modifying the CL-data based on amount of the errors calculated by measurement results of workpiece shape. By this method, however, the shape errors cannot be compensate accurately in case of 5-axis machining, because the final machining shape may not a copy of motion trajectory of tool functional point due to the motion errors of translational and rotary axes. In this study, a modification method of CL-data which based on the amount of motion errors of tool center point trajectory during the machining motion is newly proposed. Simulation and experiment of wing profile machining motion is carried out to confirm the effectiveness of the proposed method. As the result, it is confirmed that the motion accuracy can significantly be improved by applying the proposed method.
