This paper discusses the high-speed intermittent motion by comparing the indexing cam- mechanism with the servo-system. The servo-system is generally composed of the position control system. The servo-system such as position control system generally contains the current limiter that is one of the non-linear elements. The intermittent motion generated by the position control system is frequently affected by the current limiter. On the other hand, the indexing cam mechanism has the problem of the distortion of the cam motion curve accompanied by its high-speed motion. The distortion of the cam motion curve is caused by the variation of speed that is led by the driving reaction. This paper presents a solution for the distortion of cam motion curve by giving the asymmetrical acceleration curve. As a result of this study, the distortion of the cam motion curve is improved by giving the longer deceleration time compared with the acceleration time.
