"WebA cam, in its simplest definition, is a mechanical link that converts rotational motion into linear motion, or vice versa. The cams on a camshaft achieve this displacement by the rotation of a radial pattern, and a follower which moves perpendicular to the rotational axis. The cam pattern on a camshaft is non-circular with a single lobe. " - Camshaft journal definition
