Now let us start on cams.Cams are like small computers as it allows the mechanism to move when a force is applied to the mechanism.It is only limited by its size.The cam must be designed with a smooth edge as the movement will be jammed if designed badly.The Basic principle of the Cam is to turn a circular motion in to one that moves up and down. This is referred to as reciprocating movement.
