BTEC Level 3 Unit 44 Fabrication Manufacturing Processes Assignment Brief

BTEC  Unit 44 Assignment Brief

Vocational Scenario (or Vocational Context)

You have just joined a manufacturing company as an apprentice product design engineer. As part of your induction have been asked to spend two weeks working on the shop floor and product development workshops. This will allow you to become familiar with the equipment and process capabilities available within the company.

As part of your induction training you have been asked to make a prototype tool box based on drawings supplied by your colleagues in the design office. This new design has not yet been put into production and the component blanks sizes have not yet been developed and verified.

You have been asked to maintain a training log book during your induction training to record your experiences, technical information and notes on your growing skills and personal development.

Task 1

You have been asked to demonstrate that you are able to prepare for and complete the manufacture of a sheet metal product consisting of at least four formed components.

To do this:

Your tutor will provide you with individual component engineering drawings and appropriate sub and general assembly drawings for a tool box. The MP3 Player Box is to be made from sheet metal product, and has at least four formed components. You need to:

• Complete research into the health and safety requirements when setting up and using fabrication manufacturing processes; and
• Manufacture the MP3 Player Box using information in the given engineering drawings, carrying out appropriate quality control checks to ensure accuracy of the finished product.

You then need to

Complete all the activities necessary to prepare for and complete the manufacture of the tool box detailed on the component and assembly drawings supplied by your tutor. During these activities you must complete a training log book to record the details of your progress, including refinements you have made to the blank design, set-up and machining parameters. The activities to complete are:

• A health and safety risk assessment of the fabrication workshop, including all the processes to be carried out, accompanied by information about how health and safety is managed and regulations that need to be met when they are using machinery.
• Component blank size calculations based on information from given engineering drawings.
• Modelling, testing and refinement of component blanks in card to confirm fit and function.

• Set up the necessary workshop equipment, including work holding devices, and machines to prepare for manufacturing of component;
• Manufacture, using at least two cutting processes and two forming processes, the component parts of the toolbox. You should refine set up and machining parameters to ensure accurate, consistent and efficient component manufacture.
• Assembly of components into a complete, finished toolbox, using at least two different joining processes. You should record the dimensions of your toolbox and compare these with the acceptable tolerances shown on your given engineering drawings.

Throughout the manufacturing processes, you should use quality control methods to check the accuracy of the formed components and finished product and use this data to help evaluate the effectiveness of the manufacturing processes used. You should also make notes on the setup and your safe, accurate use of tools and equipment used to fabricate the components.

Checklist of Evidence Required

• A training log book containing notes, sketches and photographs of the activities undertaken in the completion of this task.
• Health and safety risk assessments
• Component models and blanks including notes explaining any modifications made.
• Manufacturing aids such as forming gauges.
• A completed sheet metal MP3 Player Box.
• Manufacturing notes that might include machine settings or refinements made during manufacture or modelling
• Tutor observation records will be required to support any evidence of practical and skills based activities recorded in your training log.
