WJEC Vocational Award Engineering Level 1/2

WJEC Vocational Award Engineering Level 1/2 In Chapter 13 you will look at what work needs to be submitted to attain a positive grade in Unit 2 and examples of different formats that could be submitted to satisfy the Assessment Criteria (AC). Machine tools The centre lathe The centre lathe is a machine used to manufacture mainly cylindrical products/objects. It can use different ‘sections’ of metal (e.g. a hexagonal section, square section, etc.) to produce shapes such as cubes, but these operations tend to be more technically advanced than just creating a cylindrical object. Centre lathes are operated both manually (in workshops) and by way of CNC in industry. Think about how many items/parts there are in the world that are cylindrical. Many different materials can be used on a centre lathe such as metals and plastics. Below is an image of a centre lathe that you would typically find in a manual workshop.
