Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

selecting appropriate units and identifying part program in accordance with current identification and/or quality system to comply with specifications

determining single probe configuration and calculating/determining and qualifying probe angles in accordance with SOPs

undertaking numerical operations, geometry and calculations/formula applicable to programming coordinate measuring machine (CMM)

positioning/aligning/securing component/part to appropriate orientation on CMM table and complying with probe configuration and calibrated angles

taking an appropriate number of hits to create an accurate manual alignment

demonstrating the correct procedure for creating direct computer control (DCC) alignment

measuring features in correct sequence and location in a single work plane

dimensioning basic features, including circles and points

verifying execution and accuracy of program and editing according to SOPs, as required

outputting results to various formats, including printer, disc or other format and backing up and archiving program, as required.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

principles and methods of coordinate measurement

principles and interpretation of geometric tolerancing

procedure for producing the part program

procedures and parameters for naming programs

procedures and reasons for determining single probe configuration

procedures for determining/calculating probe angles

Assessment Conditions

Assessors must:

have vocational competency in programming coordinate measuring machines at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
