The splinedyne method of cam design is a variation on the poly-dyne method that uses B-spline functions to obtain superior control of follower motion and its derivatives in combination with a dynamic model of the follower train to minimize vibration in the follower at any one design speed. This paper presents the results of the application of this technique to an automated assembly machine cam-follower train whose vibratory behavior before redesign was limiting machine speed and causing increased product scrap rate due to impacts and vibrations. The improved splinedyne system contributed to a measured 14% increase in production rate in combination with a 1 % reduction in scrap rate from that station.
