  • Laser cutting
  • Bending
  • Machining (turning, milling etc)
  • Grinding
  • Tapping
• Good knowledge of best practices – for example using radii to reduce stress concentration in parts, rounded edges for neat safe finishes, chamfers and leads for easy of fitment, ergonomics and safety
• Good, practical knowledge of effective guarding design (neat, simple, fit for purpose)

Tests to determine fitness for purpose

• Check draughting portfolio – body of work that can demonstrate what the person has done in the past and on their own (complexity and diversity of work)

Measuring

• Measurement test with Vernier
• Measurement test with – Inside & Outside micrometre

Dimensioning and tolerance knowledge testing

• Give a seal type and size – must correctly specify groover width, shaft size etc.
• Specify what is the best type bearing to use for application A and to select one from a catalogue

Solid works test and taking instruction test

• Speed and accuracy of work test (Solid works) – 1 x basic laser cut drawing, 1 x basic shaft drawing and 1 x sheet metal part
• Insert a BOM with template
• Record and run SolidWorks macro

Knowledge test

• Tolerance symbol
• Welding symbol
• Hydraulic component symbols
• Planning test (give a complex project task – and get the person to break the task down and develop a plan for the completion of the task).
