Cam


Part of a machine that converts circular motion to linear motion or vice versa. The edge cam in a car engine is in the form of a rounded projection on a shaft, the camshaft. When the camshaft turns, the cams press against linkages (plungers or followers) that open the valves in the cylinders.

A face cam is a disc with a groove in its face, in which the follower travels. A cylindrical cam carries angled parallel grooves, which impart a to-and-fro motion to the follower when it rotates.
