Design and Technology (D&T) KS3: Marking shapes on metal

This short film demonstrates a variety of techniques that can be used to mark out most shapes on metal.

These techniques can be used for a huge range of RMT, product design and engineering applications and across many D&T projects.

Teacher Notes

Points for discussion

  • The differences and similarities between marking on metal and on wood and plastics.
  • The importance of accurate marking out as a basis for project quality control.
  • Are there any differences between marking out on steel as opposed to, for example, copper, aluminium or brass?
  • How can techniques from other disciplines, for example maths or art and design, be used to mark out more complex shapes on a metal?
  • How can we use templates to mark out on repeated pieces of material to batch produce identical components?
  • How, ideally, might you use a CAD/CAM method like laser cutting or CNC plasma cutting, to produce similar items commercially?

Suggested activities

Marking out on metal is used in the manufacturing process of a huge range of metal-based items and components, for example:

  • Garden tool blades and tangs
  • A bottle opener, FPT tool or a more open-ended multi-tool design and manufacture project
  • Candle holders
  • Ornamental ironwork and jewellery
  • A whole range of potential components for lighting projects
  • Tool-making projects
  • A huge range of components that can be made for KS4 D&T coursework

Curriculum Notes

Suitable for teaching design and technology (D&T) at KS3/KS4 in England, Wales and Northern Ireland, and 3rd/4th levels in Scotland.
