Level 4 – Mechanical Workshop Practices
Unit code L/615/1484
Unit level 4
Credit value 15
The complex and sophisticated engineering manufacturing processes used to mass produce the products we see and use daily has its roots in the hand-operated lathes and milling machines still used in small engineering companies. To appreciate the fundamentals underpinning complex manufacturing processes, it is essential that engineers are able to read engineering drawings and produce simple components accurately and efficiently.
This unit introduces students to the effective use of textual, numeric and graphical information, how best to extract and interpret information from engineering drawings, and the practices of workshop-based turning and milling machining.
On successful completion of this unit students will be able to identify the mechanical measurement and quality control processes to analyse the dimensional accuracy of a machined component; operate machining equipment to produce a range of components to specification; explain the importance of material selection when choosing the most appropriate machining process; and apply safe working practices throughout.
By the end of this unit students will be able to:
- Identify the potential hazards that exist when operating machine tools and bench fitting equipment, with reference to the appropriate health and safety regulations and risk assessment
- Operate a manual lathe and milling machine to produce dimensionally accurate engineering
- Interpret information from engineering drawings and operate measuring tools and work-holding equipment to check dimensional accuracy of machined components.
- Explain mechanical measurement and quality control
