Application

This unit of competency defines the skills and knowledge required to write, trial and edit programs for a range of coordinate measuring machines (CMMs) to measure features of parts in multiple planes using multiple probes.

Where programming using single probes in a single plane is required unit MEM12021 Program coordinate measuring machines should be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

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 (2) occasions and include:

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

determining program parameters from job instructions, specifications, charts, lists, drawing and other applicable reference documents

selecting suitable probes and determining probe configuration and determining and qualifying probe angles in accordance with SOPs

undertaking numerical operations, geometry and calculations/formula for determining program parameters and checking tolerances

demonstrating the correct procedure for creating multiple direct computer control (DCC) alignment and integrating new and existing DCC sub-routines

constructing geometric features for the program and reviewing and editing program to specification

changing system-wide operations to ensure the most efficient operation of the program

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

Knowledge Evidence

Assessment Conditions

Assessors must:

have vocational competency in programming coordinate measuring machines (advanced) 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.
