What is wasting (removing material)?Show answer
Wasting cuts material away to leave the wanted shape. Examples: sawing, drilling, filing, turning on a lathe (cylindrical parts), milling (flat faces and slots), routing, and laser cutting and CNC machining for precision and automation. Wasting is versatile and accurate but produces offcuts and swarf, so it is wasteful of material.
What is process depends on scale?Show answer
Choosing a high-tooling process for a one-off. Injection moulding or die casting for a single prototype is the wrong call because the tooling cost is not recovered. Match the process to the volume.
What is q1?Show answer
Name one wasting process and one deforming process, and state what each does to the material. [4 marks]
What is q2?Show answer
Explain why sand casting, not die casting, would be used to make a single prototype engine bracket. [3 marks]
