URN: SEMAUT3039
Business Sectors (Suites): Automotive Engineering Suite 3
Developed by: Enginuity
Approved on: 2020

Overview

This standard identifies the competences you need to cut and shape sheet materials to produce components for experimental vehicle development activities, in accordance with approved procedures. You will be required to select the appropriate tools and equipment, and to check that they are in a safe and serviceable condition to use. You will be expected to use a range of different sheet materials, including existing vehicle components, ensuring efficient use of them. In carrying out the cutting and shaping activities, you will need to use a range of hand tools, portable power tools and simple machines to produce a variety of shapes, profiles and forms.

Your responsibilities will require you to comply with organisational policy and procedures for the sheet metal cutting and shaping activities, and to report any problems with the activities, materials, tools or equipment that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying sheet metal cutting, shaping and forming procedures and instructions. You will understand the cutting and shaping methods and techniques used, and their application, and will know about the tools, equipment, materials and consumables, in adequate depth to provide a sound basis for carrying out the activities to the required specification.

You will understand the safety precautions required when working with the sheet metal cutting and shaping equipment. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
