Description
This unit covers setting and operating coordinate measuring machines (CMM). It includes setting up/orienting components, selecting and activating part programs, preparing the machine, editing programs and measuring components.
Notes
Elements and Performance Criteria
1. Identify job requirements
- 1.1. The measurement to be made is determined from instructions/plans and relevant job specifications.
- 1.2. Drawing information is interpreted correctly, datums established and the range of tolerances applying to components is understood.
2. Set up/orient components
- 2.1. Pre-start checks are undertaken to standard operating procedures.
- 2.2. Correct safety procedures are observed and all equipment is checked for safe operation.
- 2.3. The most appropriate method of clamping/support is determined to minimise distortion and maximise measuring access.
- 2.4. Component/fixture/clamping devices are correctly set up and oriented.
3. Select and activate part programs
- 3.1. Part program is identified according to standard operating procedures as required.
- 3.2. Part program is verified.
- 3.3. Selected part program is activated according to standard operating procedures.
4. Prepare CMM
- 4.1. Probe configuration is determined according to specifications.
- 4.2. Probe configuration is adjusted on coordinate measuring machine according to standard operating procedures.
- 4.3. Probe angles are checked for compliance and adjusted as required.
- 4.4. CMM is re-set/re-calibrated.
- 4.5. Probes are manually aligned for one-off components.
5. Edit part programs
- 5.1. Part program is edited to compensate for errors or changes to component specifications.
6. Measure components
- 6.1. Components are measured and checked for conformance to specification.
- 6.2. Data/report is produced
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Measurement
Includes those which can be measured directly and those that require to be constructed mathematically
Probe
May include solid or electronic trigger probes
Coordinate measuring machine
Manual and machines fitted with microprocessors. Machines may also include horizontal, vertical and gantry tie machines

EVIDENCE GUIDE
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.
Overview of assessment
A person who demonstrates competency in this unit must be able to set and operate a coordinate measuring machine.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with setting and operating coordinate measuring machines or other units requiring the exercise of the skills and knowledge covered by this unit.
Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
