When the flanks of the cam connecting the base circle and the nose circle are of convex circular arcs, then the cam is known as circular arc cam.

In this case, as its name suggests, the displacement diagram of the follower is generated from a cycloid.

The uniform acceleration and retardation motion is also known as parabolic motion.
