What is the main function of a cam and follower system?

The primary function of a cam and follower system is to convert rotary motion into linear motion. In this system, a cam, which is typically a rotating or sliding piece, has a specific shape designed to control the movement of the follower. As the cam turns, its profile pushes the follower in a specific linear direction, which can be used for various applications such as opening and closing valves or operating machinery components at precise times. This transformation allows for controlled and synchronized movements in mechanical systems, making the cam and follower an essential mechanism in many engineering applications.
