5-axis controlled machining centers with three linear axes and two rotary axes have been developed to produce mechanical parts and molds with complicated shape. Those machining centers are generally constructed at least by two links with rotational mechanism. The evaluation method of the motion in orthogonal three planes has been developed. However, any evaluation method for five-axis controlled machining centers including A and C axes has not been developed. In this study, the motion accuracy of the machining centers simultaneously controlled three and five-axis motion is discussed. Specially, simultaneous five-axis control motion is newly proposed, and a ball-bar method is applied to measure the motion accuracy.
