| Lesson Topic: The use of the following processing techniques: wastage (cutting with hand and machine tools, including laser cutter, vinyl cutting machine, drilling, using hand, powered and press drills, turning, using a wood lathe and centre lathe, milling and rou |
Learning Objective/s:
- Describe key cutting, drilling, turning, milling and routing techniques and the materials they are suited to.
- Compare the accuracy, speed and waste of hand tools versus machine tools.
- Apply correct safety procedures and set‑up for each processing method.
- Evaluate which processing technique best meets design tolerances and production volume for a given component.
|
Materials Needed:
- Projector and screen for presentation.
- Sample raw materials (cardboard, acrylic sheet, wood blocks, metal blanks).
- Hand tools – utility knife, hand saw, tin snips, hand drill.
- Machine tools – band saw, laser cutter, vinyl cutter, powered drill, press drill, wood lathe, centre lathe, milling machine, router.
- Safety equipment – safety goggles, ear protection, gloves.
- Worksheets/handouts for note‑taking and assessment.
|
Introduction:
Begin with a quick video showing a component being produced using different processing techniques to spark curiosity. Ask learners what factors they think influence the choice of tool. Outline today’s success criteria: identify techniques, compare their capabilities and demonstrate safe set‑up.
|
Lesson Structure:
- Do‑now (5'): Students list as many cutting and shaping tools as they can recall.
- Mini‑lecture (10'): Overview of wastage techniques – hand vs. machine tools, laser, vinyl cutter, drills, lathes, milling/router.
- Demonstration (15'): Teacher shows safe set‑up and operation of a laser cutter and a hand drill, highlighting accuracy and waste.
- Group activity (15'): Teams compare two techniques (e.g., hand saw vs. band saw) using the summary table and record advantages/limitations.
- Safety check (5'): Quick quiz on PPE and machine guarding.
- Plenary (5'): Whole‑class discussion linking technique choice to material, tolerance and production volume.
|
Conclusion:
Recap the key factors that drive the selection of a processing technique and emphasise the importance of safety. Students complete an exit ticket matching a scenario to the most appropriate tool. Assign homework: research a real‑world product and justify the processing methods used.
