- A cam is 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 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.
