Grade: Date: 25/02/2026
Subject: Design and Technology
Lesson Topic: The advantages and disadvantages of different methods of CAM production.
Learning Objective/s:
  • Describe the main CAM production methods and their key characteristics.
  • Compare the advantages and disadvantages of each CAM method.
  • Evaluate the suitability of a CAM method for specific design requirements using selection criteria.
  • Apply a decision‑making process to choose an appropriate CAM method for a given case study.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Printed handouts of method comparison tables
  • Decision‑making flowchart poster
  • Sample material pieces (metal sheet, plastic, wood)
  • Computer with CAD/CAM demo software
  • Worksheet for evaluation and exit ticket
Introduction:

Begin with a short video showing modern factories using robots and CAM machines to capture students' interest. Ask learners what they already know about computer‑aided manufacturing and link it to previous CAD lessons. Explain that by the end of the session they will be able to identify the strengths and limits of each CAM method and justify the best choice for a design brief.

Lesson Structure:
  1. Do‑now (5'): Quick quiz on CAM terminology on the board.
  2. Mini‑lecture with slides (10'): Overview of the six main CAM methods.
  3. Group activity (15'): Each group analyses one method using the handout, fills a pros/cons list.
  4. Whole‑class discussion (10'): Groups share findings; teacher compiles a master comparison chart.
  5. Case‑study simulation (15'): Using the flowchart, groups decide the most suitable CAM method for a given product brief and justify their choice.
  6. Exit ticket (5'): Write one advantage and one disadvantage of the chosen method.
Conclusion:

Recap the key advantages and disadvantages discussed and highlight how the selection criteria guide method choice. Collect exit tickets to check understanding, and assign homework: research a real‑world product and identify which CAM method was likely used, providing a brief justification.
