Produce advanced jewellery or silverware designs using computer aided design and manufacturing

Business Sectors (Suites): Jewellery Manufacture, Silversmithing and Allied Trades
Developed by: Creative & Cultural Skills
Approved on: 14 Aug 2015


This standard covers the skills to design, develop and produce new, advanced products using computer-aided design (CAD) and computer-aided manufacturing (CAM) technology.  You will be required to produce CAD designs, account for common manufacturing issues at design stage to ensure designs are workable with the manufacturing equipment and materials, transfer the design data to CAM systems and manufacture final products using this technology. You will design and test complex pieces, refining concepts to achieve the desired final product.

As a valuable addition to traditional manufacturing practices it is essential that candidates demonstrate a thorough understanding of the construction, polishing and finishing of the work piece to ensure this meets the benchmark for pieces made using traditional techniques, please refer to the related NOS list in the additional information section for related standards.

You must also ensure that you understand what you need to do to perform the required activities and attain the required standards of workmanship. You will be expected to take personal responsibility for your actions and for the quality and accuracy of the work.

Performance criteria

You must be able to:

  1. select the software for the required specification in line with industry best practice
  2. design complex pieces using CAD in line with project needs
  3. deal with problems with faulty equipment or software operation in line with industry best practice
  4. use CAD software to produce complex designs for jewellery or silverware products in line with industry best practice
  5. design out common issues which may cause problems or delays when manufacturing the product in line with industry best practice​
  6. transfer CAD modelling data to CAM systems in line with industry best practice
  7. select the CAM materials to be used in complex prototypes in line with project needs
  8. produce complex sample models and prototypes using CAM equipment in line with industry best practice
  9. refine design using prototypes in line with project needs
  10. test prototypes with clients to gain customer insight and feedback in line with project needs
  11. produce final product using CAM systems in line with industry best practice
  12. keep records of supporting documentation, files and folders in agreed format in line with the needs of the project and the design specification
  13. check the work for defects in line with project needs
  14. take action to rectify any defects detected in line with industry best practice
  15. complete the work to the given specification in line with workplace instructions

Knowledge and Understanding

You need to know and understand:

  1. safety precautions to be taken when working with CAD and CAM machinery
  2. range of software available and uses with different projects
  3. how to use CAD workstation software and hardware
  4. common faults that can occur with CAD/CAM techniques and processes and the procedures to be undertaken if faults occur
  5. principles of computer generated graphics and drafting skills
  6. how to inspect for errors on any CAD/CAM designs made and actions to take
  7. types of materials that can be used in CAM and the different results they give
  8. common manufacturing problems with different equipment and materials and how to avoid these in the design stages of production​
  9. CAD rendering techniques
  10. documentation to be completed at the end of CAD/CAM activities
  11. mathematical calculations used in design
  12. how to interpret drawn images
  13. current engineering drawing practice conventions
  14. CAM techniques and processes
  15. how to communicate design ideas to clients
  16. client testing methods
  17. the importance of customer insight before full manufacture
  18. how to review and refine designs based on prototypes
  19. how to check that the final prototype meets the needs of the specification
  20. best practice in CAD and CAM within chosen jewellery industry
  21. the importance of following the given specification and timescales
  22. common CAM defects and ways to rectify these
  23. how to record, store and protect newly completed designs
