VCSE Engineering

Mae disgrifiad y cymhwyster yn Saesneg yn unig, gan ei fod wedi ei gymryd o fanyleb Saesneg CBAC.

VCSE Engineering asks learners to read engineering drawings and technical sources closely, use precise technical vocabulary, write an operations plan and risk assessment, report faults and evaluate the quality of their own work, while the Unit 1 tasks ask them to read a case study and weigh the benefits and challenges of an engineering project in Wales. Numeracy runs through every unit: measuring to tolerances with callipers and micrometers, finding missing dimensions and angles on drawings, converting units, and calculating area, volume, waste, feeds and speeds and Ohm's law, much of it tested in the one hour Unit 3 written test. The single biggest thing KS3 should build is accurate measuring in millimetres against a stated tolerance, together with the confidence to use a formula such as spindle speed or Ohm's law with the right units.

Sgiliau sy'n defnyddio Cymhwysedd strategol

  1. Measuring accurately and working to tolerances

    Asesu: Yn yr arholiad ac mewn gwaith cwrs

    Learners measure and mark out with steel rules, vernier, dial and digital callipers and micrometers, identify the tolerances a component needs, and evaluate the accuracy of their dimensions against the drawing. Unit 3 examines the purpose of gauging and measuring tools and why each suits an operation.
