Elements and Performance Criteria

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.
Manufacturers' catalogues
Manufacturers' catalogues may include any appropriate manufacturers' catalogues that contain replacement parts that conform with specifications and operational requirements
Appropriate workshop practices
Appropriate workshop practices may include:
drilling
scraping
filing
reaming
tapping
threading
Fitting principles and techniques
Fitting principles and techniques may include:
limits of tolerance
allowances and clearances
effects of wear, stress, temperature
types of fits - clearance transition interference
press fitting methods
force fits
shrink and freeze (expansion) fits
keyed fits
taper fits
lateral and radial forces
backlash
configuration and mating of parts
applied use of precision tools and measuring equipment
engineering components - shafts, single and multi-throw crankshafts, cams and journals, bearings and bearing surfaces, keys
squareness, roundness, concentricity, flatness, straightness, surface finish and angular correctness
datum and centrelines
tapping, reaming and broaching

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 repair and fit engineering components to specifications in both workshop and site environments. 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 apply the skills covered in this unit of competency in new and different situations and contexts. Critical aspects of assessment and evidence include:
obtaining manufacturer's and enterprise specifications for equipment, materials and components
checking components visually and dimensionally in the workplace including tolerances, allowances, clearances and limits
repairing and fitting components and assemblies in a workshop environment to required specifications
repairing and fitting components and assemblies in a production or other work site environment
manufacturing and fitting components including commissioning and return to service checking of component and equipment through first off production or other recognised return to service checking procedure
procedures for out of specification modification/alterations.
Context of and specific resources for assessment
This unit has been developed to support training in and recognition of trade level competency repair and fit of engineering components as applied to a trade level fitting and machining work environment. Assessment should emphasise a workplace context and procedures found in the candidate's workplace.
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.
Method of assessment
Typically, persons engaged in Engineering Tradesperson - Mechanical work are required to apply their repair and fit skills and techniques across a range of jobs and specifications.
A single assessment event is not appropriate. On the job assessment should be included as part of the assessment process wherever possible. Where assessment occurs off the job, judgement must consider evidence of the candidate's performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit.
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
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with repair and fit of engineering components or other units requiring the exercise of the skills and knowledge covered by 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.
