Cam mechanisms

Cams in a product

Develop ideas through cross-section diagrams

Wood construction and joining techniques

Make an accurate box frame

Assemble cam mechanisms

Test and adapt cam mechanisms

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.
