+A **cam** is a rotating or sliding piece in a [mechanical linkage](/wiki/Mechanical_Linkage) used to transform simple motion into a more complex, often reciprocating or oscillating, movement. Its unique profile precisely controls the action of a [follower](/wiki/Follower), allowing for specific timing and force transmission within a system.
