Required Skills
Required knowledge |
types, characteristics, uses and limitations of jigs and fixtures criteria for selecting material for use in jigs and fixtures requirements for cutting, shaping and joining materials identification of equipment, processes and procedures workflow in relation to the use of jigs and fixtures |
Evidence Required
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Critical Aspects of Evidence | Interpret work order and locate and apply information Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment Identify materials used in the work process Follow work instructions, operating procedures and inspection practices to: minimise the risk of injury to self or others prevent damage to goods, tools, equipment or products maintain required production output and product quality The selection of materials and the construction of a minimum of three different types of jigs/fixtures, including one for a shaping machine and one which is adjustable Work effectively with others Modify activities to cater for variations in workplace contexts and environment |
Resource Implications | Job context, materials and equipment for jig or fixture construction. |
Method of Assessment | Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts. Assessment should be by direct observation of tasks and questioning on underpinning knowledge. Assessment should be conducted over time and may be in conjunction with assessment of other units of competency. |
Context of Assessment | Assessment may occur on the job or in a workplace simulated facility with relevant process equipment, materials, work instructions and deadlines. |
