a bar that follows the movement of the cam disc

a device that holds the follower in position

Cams in a product

Design and technology

This unit develops pupils' knowledge of mechanisms through cams. Pupils will develop knowledge of the properties of wood and apply this by selecting suitable materials for functionality. Knowledge of wood construction and joining techniques are introduced and applied through making an automaton.

Cams: automata
