Theory of Machine
In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done

Because of difficulty in manufacturing cam profile
In order to have acceleration in beginning and retardation at the end of stroke within the finite limits
Because of loose contact of follower with cam surface
