This paper proposes an optimal approach of cam curves to control the residual vibration with indexing cam mechanisms. The cam curve is described with a uniform B-spline and then the values of B-spine control points are optimized through minimizing the performance value of index function. A practical dynamic model of indexing cam mechanism, which has been experimentally identified in reference (10), is accepted in the approach. The index function combines one strict limitation with other two non-strict restrictions so that no residual vibrations happen with the obtained cam curves after the end of indexing motion, and both the maximum acceleration and transient vibration of the follower output within the indexing action are kept in a lower level. Through some performance comparisons, it is sufficiently illustrated that the obtained cam curves are superior in respects to those applied in engineering practices. The algorithm in simple and the programming is easy together with enough calculation efficiency for engineering applications.
