Elements and Performance Criteria

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.
Machine and equipment components
Machine and equipment components for this unit are limited to components peforming mechanical functions. Examples include:
shafts
bearings
couplings
power screws
gear drives
spur gears
chain and belt drives
brakes
clutches
Standards and codes
Standards and codes refer to all relevant Australian and international standards and codes applicable to a particular selection of mechanical machine and equipment components task
Appropriate licensed technical and professional assistance
Appropriate licensed technical and professional assistance may include:
technical support and advice relating to elements which have intrinsic dangers, such as:
high pressure
energised fluid vessels
high temperatures and heat energy capacity
wiring with high current control voltages above extra low voltage
professional support for technologies, such as:
specialist electric motor drives and controllers
specialist materials, plastics, metal alloys and nano materials
special processes, foundry, alloy welding, heat treatment, sealing and fastening
Sustainability implications
Sustainability is used to mean the entire sustainable performance of the organisation/plant, including:
meeting all regulatory requirements
conforming to all industry covenants, protocols and best practice guides
minimising ecological and environmental footprint of process, plant and product
maximising economic benefit of process plant and product to the organisation and the community
minimising the negative WHS impact on employees, community and customer
Analysis of machine and components
Analysis of machine and equipment components may include:
static and dynamic analysis of loads
the stresses and deformations resulting
the transmitted power, torque and speed
machine/operator interface in terms of ergonomics and safety
environmental effects, including noise, energy efficiency, heat generation and dust generation
graphical and mathematical methods and software options
Appropriate computer-aided solutions and validation techniques

Appropriate computer-aided solutions include:
performance analysis and computer-aided design (CAD) modelling
Validation techniques include:
comparison of traditional solutions for simple design problems with software solutions to the same design problems
review of previously implemented design challenges which were completed using the software

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 select a wide variety of mechanical machine and equipment components for safety, economy and fitness for purpose. Selections must be able to be justified through appropriate engineering analysis.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
determine component arrangement, limits, fits and clearances, assembly, fastening and alignment of components
investigate sustainability implications of components selection task
review features and functions of machine and equipment components, design loads, working stresses, allowable deformations and factor of safety
select and specify machine components, including arrangement and assembly requirements
evaluate machine components and arrangements for compliance with WHS and regulatory requirements and risk assessment
report and document results.
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, then a simulated working environment 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.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
