This study was conducted for developing the testing methods by means of simultaneous five-axis motion in five-axis controlled machining centers with a double pivot spindle head. In this paper, the five axis motion was simulated considering the measurement by a ball bar system and the relative distance change between both balls of the table side and the spindle side was simulated, changing the ten deviations inherent to the five-axis machining centers. Two of the three kinds of simultaneous five-axis motions were introduced for the identification of the deviations inherent to the five axis machining centers. In the first step, the ball bar was set parallel to the A-axis of the spindle head and in the second step the distance between the ball of the spindle side and the center of the A-axis was extended and then the measurement was repeated. In the third step, the ball bar was set tangential to the A-axis rotation. The observation equations and the geometric analysis were applied to the identification. The ten diviations inherent to the machining centers were accurately identified through these three steps. It was confirmed that the proposed five axis motion was effective for valuating the accuracy of the five-axis machining centers compared with our previous proposed method.
