Explanation:

Cam: 

The cam is a rotating part that provides reciprocating or oscillating motion to the follower by direct contact.

This part is essentially used to change the movement from the rotary to linear.

Follower: 

The follower is a rotating or oscillating element of a machine that follows the movement of the cam by direct contact. When a cam travels in reciprocating movement, the follower moves parallel on the cam axis.

Cams are classified according to the:

  • Basic shapes
  • Follower movement
  • Manner of the constraint of the follower.
