MEM12019B
Measure components using coordinate measuring machines
Application
This unit applies where the operator is following established processes, practices and standard operating procedures and is responsible for providing dimensional detail required for adjustment or checking of the manufacturing process. Work is carried out autonomously using predetermined standards of quality and safety. Operators would be expected to have competence in basic setting and adjusting of machines. An appropriate level of measurement skill should be selected with this unit. Where it is required to use tools, then unit MEM08001B (Use hand tools) should also be selected. Where basic operation excludes setting up components and manually aligning probes, Unit MEM07024B (Operate and monitor machine/process) should be selected. Where other machines/processes are to be adjusted as a consequence of the CMM operation, appropriate machining/process operation units should also be selected. Band: A Unit Weight: 4 |

Required Skills
Required skills |
Look for evidence that confirms skills in: reading and following routine, familiar information for loading, setting probes and measuring components identifying and following pre-start check procedure following safety procedures selecting specified fixture/clamping device positioning and clamping components taking manual hits and determining probe alignment verifying probe/s configuration to specifications selecting and activating part programs as required where machine is fitted with microprocessors verifying and confirming correct program operation applying correct measuring techniques reporting out of tolerance measurements shutting down the part program removing and handling components cleaning machine and site following verbal instructions orally reporting routine information |
Required knowledge |
Look for evidence that confirms knowledge of: task-related information on job sheets or equivalent pre-start checks hazards and control measures associated with operating a CMM, including housekeeping use and application of personal protective equipment safe work practices and procedures fixtures/clamping devices and their uses storage location and procedures fixing/clamping methods procedures for undertaking pre-measurement manual hits for manual alignment procedures for checking probe configuration procedures for running and verifying part program methods/techniques for interpreting results procedures for reporting results and recommendations for adjustment procedures for shutting down part program procedures to safely remove and handle components required cleaning tasks and the importance of cleaning the CMM effects of contamination |
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. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to measure components using a coordinate measuring machine in accordance with instructions. |
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 measuring components using a coordinate measuring machine 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. |
Guidance information for assessment |
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. | |
Probe | Solid or electronic trigger probes |
Measurements | Are limited to those which can be measured directly and do not require to be constructed mathematically |
Coordinate measurement machine | Manual machines and machines fitted with microprocessors |
