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.
Jigs and fixtures
Jigs and fixtures are used to position, hold and support components for assembly, fabrication or machining operations. Jigs also guide operations, such as drilling. Jigs and fixtures are specially designed so that large numbers of components can be machined or assembled identically while maintaining the correct relationship and alignment between the tool and the work piece, and to ensure interchangeability of components. A jig or fixture is designed and built to hold, support and locate a component (part) to ensure that it is drilled, machined or fabricated within the specified limits
Templates
Templates are production tools used to accurately manufacture duplicate and interchangeable parts and may perform positioning and guidance functions as well as profile checking for machining and fabrication operations
Gauges
Gauges are used to check dimensions of components, machining operations or assemblies. For this unit gauges refers to:
specifically manufactured items to allow quick dimensional or other checks, for example, go/no-go gauges with references or use of graduated devices or instruments
Features and functions, of jigs, fixtures, templates and gauges
Features and functions of jigs, fixtures, templates and gauges include:
materials used in their construction
method of fabrication (e.g. welding and machining)
dimensions and tolerances
method of holding or locating work pieces or production items
method of installation and any capacity for operator adjustment during use
method of adjustment for production changeover
where the jig, fixture, template or gauge is being used by someone other than the designer or manufacturer, the degree of training required for its correct use
any limitations on the use of the jig, fixture, template and gauge
cost
degree of saving generated by the jig, fixture, template or gauge over alternatives. The saving may be in:
quality
error rate
production capacity
labour requirement
WHS, regulatory requirements and enterprise procedures

WHS, regulatory requirements and enterprise procedures may include:
WHS Acts and regulations
relevant standards
codes of practice from Australian and overseas engineering and technical associations and societies
risk assessments
safe work practices
state and territory regulatory requirements
Standards and codes
Standards and codes refer to all relevant Australian and international standards and codes applicable to evaluation of jigs and fixtures
Appropriate technical and professional assistance
Appropriate 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
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
Systems thinking

Systems thinking refers to the conduct of engineering work in a manner that demonstrates knowledge of how the interaction of different technical systems on equipment, machinery or structures, as well as the skills and techniques of personnel, combine to perform or support engineering-related operations, processes or projects. It embraces determining or establishing how the function of each technical system or component, as well as the skills and techniques of personnel, effects or potentially may effect, outcomes. Systems should be interpreted broadly within the context of the organisation and depending on the project or operation can include equipment, related facilities, material, software, internal services and personnel, and other organisations in the value chain
Continuous improvement implementation
Continuous improvement implementation may relate to plant, products, processes, systems or services, including design, development, implementation or manufacture, commissioning, operation or delivery and maintenance.
Improvement processes may include techniques, such as:
balanced scorecard
current and future state mapping
measuring performance against benchmarks
process improvement, problem solving and decision making
data management, generation, recording, analysing, storing and use of software
training for improvement systems participation
technical training
Constraints and contingencies
Constraints and contingencies may be:
financial
organisational, procedural or cultural
physical constraints, such as limits to resources, limits to site access or logistical limitations
Lean principles
Lean principles affecting tooling and related processes include:
tooling and processing costs
capacity and responsiveness to product demand
quality of product
reliability of tooling, process and supply
waste minimisation which includes ease of tool change

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 evaluate jigs, fixtures, templates and gauges and their applications within manufacturing processes for safety, economy and fitness for purpose.
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 parameters and context of jigs, fixtures, templates and gauges in manufacturing processes
review design and construction features, functions, applications and limitations of jigs, fixtures, templates and gauges
identify principles, design, analysis techniques and software required to evaluate and optimise jigs, fixtures, templates and gauges and related manufacturing processes
evaluate WHS, regulatory and risk management compliance
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.
