Elements and Performance Criteria

1. Identify part program parameters
   • Job specifications and requirements are correctly established.
   • 1ppropriate units are selected to comply with specifications.
   • Part program name is specified according to standard operating procedures.
2. Establish single probe configurations
   • Single probe configuration is determined according to standard operating procedures.
   • Probe angles are determined and qualified in accordance with standard operating procedures.
3. Position/align component
   • Component/part is positioned and oriented correctly.
   • Manual alignment is created according to standard operating procedures.
   • Single Direct Computer Control (DCC) alignment is created according to standard operating procedures.
4. Measure features
   • Features are measured correctly.
   • Probe movement parameters are defined in accordance with standard operating procedures.
   • Basic features are dimensioned according to specifications.
   • Operator notes are reported.
   • Dimension descriptions are inserted.
5. Verify and back up the program
   • Execution and accuracy of program is verified according to standard operating procedures.
   • Program is edited, if required.
   • Results are output to various formats according to standard operating procedures.
   • Program is archived and backed up.

Required Skills

Required skills

Look for evidence that confirms skills in reading and interpreting information on written job instructions specifications charts lists drawings and other applicable reference documents using methods of coordinate measurement analysing and establishing part program parameters checking and clarifying information entering information onto proformas and standard workplace forms navigating and entering data in applicable program software checking for conformance to specifications using precision measurement equipment measuring components to specified tolerances undertaking numerical operations geometry and calculationsformulae within the scope of this unit following verbal instructions orally reporting routine information selecting the correct units for the part program identifying the part program in accordance with current identificationquality system determining the probe configuration calculatingdetermining and qualifying probe angles positioningaligningsecuring componentpart 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 DCC alignment measuring the part features in the correct sequence and location in a single work plane defining and verifying the parameters correctly dimensioning basic feature such as circles points etc producing and inserting explanatory notes for the operator inserting all necessary dimension descriptions running the part program and verifying the accuracy of the results editing where nonconformance is identified outputting results to printer disc or other format as required archiving and backing up part program

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 program a coordinate measuring machine Competency in this unit cannot be claimed until all prerequisites have been satisfied
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 programming 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 supervisors 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

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.
