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. 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 deviations inherent to the machining centers were accurately identified through these three steps.
