In terms of the realization for high accurate and effective machining of complicated shape having under cut shape and free formed surface, five axis controlled machine tools become indispensable because they have any tool position and attitude to avoid the collision between machine tool elements and work piece. These five axis machine tools have a technical problem as machining accuracy, which is inferior to that of three axis NC machine tools. In order to estimate the motion accuracy of NC machine tools, various kinds of certificate methods like circular cone cutting test prescribed with NAS and DBB method using the circular motion have been developed and standardized. These methods are mainly used for the motion testing of three axis NC machine tools and therefore new method and measuring equipment for five axis NC machine tools are needed. This study aims at developing the motion accuracy measurement system which can measure various kinds of motions like linier motion, circular motion and continuous curved motion under simultaneous five axis controlling and establishing the compensate method of tool motion. Consideration is added from the viewpoint of motion accuracy using measurement system developed in this report in case simultaneous five axes control motion command value from CL data. About object machine tool, it is reported about framing of the most suitable NC data.
