Unit Summary
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.
Lesson Summary
You will learn to integrate a cam mechanism into an automaton.
Key Notes
- Axles at 90 degree angles will allow more accurate connection to the cams.
- More than one cam can be added to the same axle.
- Designs may require loose fit or tight fit joints.
- Drilling techniques need to be conducted safely.
Vocabulary To Learn
- assemble: bring separate parts together
- components: separate parts of a larger whole
- drill bit: cutting tool used to make holes
- chuck: a device for holding a tool in place
Common Mistakes To Avoid
- Drilled and pierced holes can be any size.
3 Quick Questions (With Answers)
