Wasting manufacturing processes for polymers

Polymers

Unit Summary

In this unit pupils will develop technical principles knowledge with an explicit focus on exam technique.

Lesson Summary

You will learn to explain and compare small-scale and industrial wasting processes.

Key Notes

  • Wasting involves removing material to shape or size a product.
  • Tools and small machines remove material in small-scale production.
  • CNC stands for Computer Numerical Control, which means that some machinery can be controlled by a computer.
  • Larger machines remove material quickly, more accurately, and consistently at scale.

Vocabulary To Learn

  • wasting: removing material to shape or size a product
  • small-scale production: making one or a few products using hand tools or basic machines
  • industrial: higher-volume production using machines for speed, accuracy and consistency
  • CNC: Computer Numerical Control - Computer-controlled machining for precise cutting and shaping

Common Mistakes To Avoid

  • The same tools and methods are used for both small-scale and industrial manufacturing.

3 Quick Questions (With Answers)

1. Explain the lesson in two key points.

Wasting involves removing material to shape or size a product. Tools and small machines remove material in small-scale production.

2. What does this key word mean in this lesson? 'wasting'

removing material to shape or size a product.

3. Correct this common mistake.

Mistake: The same tools and methods are used for both small-scale and industrial manufacturing. Correction: The scale of production heavily influences tool choice, speed, accuracy, and repeatability.
