Abstract : In this paper, ping finite cam motion function (CMF) is designed instead of jerk finite program. Work is done on B-splines. Control points (CP), which are defined by angular positions of intermediate knots, are introduced in B-splines to minimize jerk of cam-follower. We studied the effects of CP on the peak values of jerk. The values of jerk and ping at end positions of each motion cycle also influence the peak values of jerk. The angular position of intermediate knots and either jerk or ping at end position are varied independently or simultaneously to optimize the peak values of jerk. Experimental analysis is conducted for measuring cam-follower performance of the newly introduced cam profile. An experimental set-up is designed, manufactured and installed for this purpose.
