Types of follower motion

Cam follower systems are designed to achieve a desired oscillatory motion. Appropriate displacement patterns are to be selected for this purpose, before designing the cam surface. The cam is assumed to rotate at a constant speed and the follower raises, dwells, returns to its original position and dwells again through specified angles of rotation of the cam, during each revolution of the cam.
Some of the standard follower motions are as follows:
They are, follower motion with,
(a) Uniform velocity
(b) Modified uniform velocity
(c) Uniform acceleration and deceleration
(d) Simple harmonic motion
(e) Cycloidal motion
