Profile Determination of Plate Cams with Oscillating Convex Arbitrary-Shaped Followers

A universal form of profile equation for a plate cam whose follower has an oscillating motion and a convex arbitrary shape is derived in this study. The applied concept is the theory of envelopes in a parametric form. The derived results can be used to determine the profile of the cam with any kind of convex shape of the followers. It is also shown that the traditional followers, such as flat-faced and roller followers, are special cases of the universal form.
