The design of varying-velocity translating cam mechanisms

A translating cam driven by an offset slider–crank mechanism has varying velocity, and the follower motion can be arbitrarily chosen for only the forward or the return stroke of the translating cam. By employing the concept of velocity instant center, the cam profile, the path of cutter, the pressure angle and the radius of curvature of the cam can be expressed parametrically, and the follower motion of the remaining stroke can be analyzed analytically. The cam profile has concave, convex and flat portions.
