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.
Designer
A designer is usually a professional engineer but may also be a scientist, engineering technologist, architect or other person with appropriate skills and knowledge for the design task. The term may also refer to situations where a team of designers are used to produce a design
Design drawing brief
The design drawing brief will be communicated to the design draftsperson and will include:
major and critical engineering specifications (e.g. dimensions, limits, fits, tolerances and materials)
required features and performance of equipment (e.g. volume, temperature and flow)
standards that must be adhered to
client requests
budget and project schedule
procedures to be followed for further clarifications
Design drawings
Design drawings is used in this unit to include all 3-D and 2-D files and hard copies produced as part of the design drawing process
Design criteria for mechanical designs
Criteria for mechanical designs may include:
function
aesthetics
manufacturability and maintainability
marketability
sustainability:
social, economic and environmental
material and energy resources
cost constraints
ergonomics, anthropometrics and physiology
facilities, plant and skills available
safety and risk
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

WHS, regulatory requirements and enterprise procedures

WHS, regulatory requirements and enterprise procedures may include:
WHS Acts and regulations
relevant standards
industry codes of practice
risk assessments
registration requirements
safe work practices
state and territory regulatory requirements applying to electrical work
Mechanical assemblies
Mechanical assemblies may include:
machines, drives and transmissions
materials handling equipment (e.g. belt conveyors, augers and pneumatic conveyors)
guards, handrails and platforms
structures, vessels and tanks
fan, ventilation, air conditioning service and ducting
manufacturing plant and process layouts
manufactured products
Mechanical components and features represented by standard conventions and graphical techniques
Mechanical components and features represented by standard conventions and graphical techniques may include:
hole basis, shaft basis and keyway tolerances and fits
dimensions, tolerances for limits and fits
materials and surface finish
weld symbols
webs, cross-sections and cutting planes
chain drives, gear sets, pulley and belt drives
threads, fasteners and springs
shafts, keyways and splines
structural sections
Features, functions and context of engineering design drawing
Features, functions and context of engineering design drawing include:
uses of design drafting for purposes, such as:
design specifications
production specifications
maintenance procedures
technical specifications and descriptions
graphical representation techniques, including orthogonal, 2-D and 3-D modelling, isometric and mechanical perspective, dimensioning, limits and fits, welding and other standard symbols
role of WHS and regulatory requirements, codes of practice, ministerial directives, risk assessment and registration requirements
availability and features of a range of standards related to mechanical plant and devices, design, maintenance and alteration
typical criteria for mechanical designs
software developments
current graphical methods compared with traditional methods
emerging developments in graphics and related engineering software
Standards and codes
This refers to all relevant Australian and international standards and codes applicable to a particular design task

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 produce a variety of graphical representations of mechanical and maintenance-related assemblies and components that are consistent with design information and relevant standards and conventions.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
select and apply design criteria to meet requirements of the deign brief
review features, functions and context of engineering drawings
develop orthographic, isometric and other 3-D graphical representations
represent mechanical components and assemblies using sketching and computer graphics
represent mechanical components and features using a comprehensive range of standard conventions and graphical techniques
represent a range of mechanical assemblies using standard graphical representations
recognise when to engage appropriate licensed technical and professional assistance for advice
provide documentation, images and files.
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.
