Unit of Competency | MEM12020B - Set and operate coordinate measuring machines |
---|---|---|---|
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. | ||
Employability Skills | This unit contains employability skills. | ||
Learning Outcomes and Application | This unit applies to a range of coordinate measuring machines (CMM). Measurement procedure is determined according to established processes, practices, and specifications. Work is carried out autonomously using predetermined standards of quality and safety. The procedures apply to both one-off and multiple components.Appropriate levels of measurement, computer operations and drawing skills should be selected with this unit. Where a range of hand tools is required, Unit MEM08001B (Use hand tools) should also be selected.Band: AUnit Weight: 2 | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. |

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: reading, interpreting and following information on written job sheets, instructions, standard operating procedures and drawings checking and clarifying task-related information entering information onto workplace documents checking for conformance to specifications measuring components to specified tolerances using methods of coordinate measurement positioning and securing components effectively selecting and running part programs loading configuring and adjusting probes checking and adjusting probe angles re-setting/re-calibrating the CMM taking manual hits identifying problems/errors in program editing program to ensure accurate operation checking results against drawings/specifications and interpreting for non-conformance |
Required knowledge |
Look for evidence that confirms knowledge of: principles and methods of coordinate measurement principles and interpretation of geometric tolerancing task-related information, symbols and terminology pre-start checks types and functions of various fixtures/clamping devices principles and methods of clamping efficient set-up/orientation procedure procedures to locate and activate part program procedures to verify changes/upgrades to part programs various probes and their uses and configurations setting and adjusting probes requirements and procedures for re-setting/re-calibrating the CMM procedure and reason for taking manual hits procedures for editing part programs procedure for interpreting results the procedure for maintaining records reporting procedures hazards and control measures associated with setting up and operating coordinate measuring machines, including housekeeping use and application of personal protective equipment safe work practices and procedures techniques, tools and equipment to measure components |
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 |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
Observation Checklist
Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice | Yes | No | Comments/feedback |
---|---|---|---|
The measurement to be made is determined from instructions/plans and relevant job specifications. | |||
