Cam and Follower

Cam and Follower Mechanism

Definition: A cam and follower mechanism is a mechanical system that converts rotary motion into linear motion. It consists of a cam (a rotating or sliding piece) and a follower (a part that moves in response to the cam’s motion).

How It Works: The cam’s shape dictates the motion of the follower. As the cam rotates, its profile pushes the follower, causing it to move in a specific path. This allows for precise control of the follower’s motion.
