An evaluation method for synchronous motion of translational and rotational axes in 5-axis machining centers is proposed. In the proposed method, the X and the C' axes are simultaneously controlled and a circular path is generated under a constant peripheral feed speed. The relationship between the diameter of the circular path and the distance between both centers of the rotary axis and the circular path is useful for evaluating the accuracy. If the diameter of the circular path is smaller than the distance between both centers of the rotary axis and the circular path, the influence of the backlash becomes strongly. If the offset between machine coordinate origin and the center of the C' axis is large, it is difficult to evaluate the inaccurate synchronization appropriately.
