In this paper, the structural configurations of 5-axis machining centers are researched, and a proposed method is applied to the measurement of the geometric deviations of the available machines, and the effectiveness of the method is discussed. The structural configurations of the 5-axis machining centers are divided into three types. The ball-bar technique is applied to the measurement of simultaneous 4-axis control motion, and the error motion is simulated using the motion analysis software. As the results, the geometric deviations in three types of 5-axis machining centers can be estimated by the proposed method. 5-axis control motion using a simplejig is proposed as alternative measurement method, and it is found that the proposed method is effective to evaluate the geometric deviations as well as 4-axis control motion.
