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

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 the uniform velocity motion is a partial parabolic motion

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

Theory of Machine
The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints)

n = (l -1) - j

n = 3(l - 1) - 2j

n = 2(l - 1) - 2j

n = 4(l - 1) - 3j

n = (l -1) - j

n = 3(l - 1) - 2j

n = 2(l - 1) - 2j

n = 4(l - 1) - 3j
