Produce engraved surfaces using advanced techiques
Overview
This standard covers the skills to use different styles of engraving to produce a decorative surface including the use of advanced techniques such as pantograph, photo-etching, laser cutting and CNC machine engraving. You will apply these advanced techniques on to a range of surfaces, for example, plated work, carved work, lettering, inside curves, multi-material combinations and repairs and restorations.
In producing engraved products, you will be required to work to instructions and to use a range of hand tools and techniques appropriate to the type of material being used and the type and style of engraving being executed.
You will be expected to take personal responsibility for your actions and for the quality and accuracy of the work carried out. During, and on completion of, the engraving operations you will be expected to check the quality of your work using visual inspection guidelines, appropriate to the aspects being checked and the specifications required. You will need to be able to recognise any defects, determine the appropriate action to rectify them, and ensure that the finished work meets the required specification.
