Application
This unit of competency covers the skills and knowledge required to plan and develop a two-dimensional pattern from which three-dimensional products or moulds can be made. Two-dimensional patterns are typically used in the fabrication, thermoforming, composites and rubber lining sectors.
This unit of competency applies to experienced operators who are required to interpret drawings and specifications, plot the dimensions and ‘develop’ solid objects into two-dimensional patterns, check and complete the pattern and solve problems within area of responsibility.
This unit of competency applies to an experienced operator demonstrating theoretical and technical knowledge and well developed skills in situations that require some discretion and judgement. The operator may work alone or as a member of a team or group and will work in liaison with other shift team members, team leader and supervisor, as appropriate.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

mechanical failure/malfunction
wrong readings
equipment malfunction/wear
materials properties
procedural errors
recognise and prioritise problems requiring action
resolve routine and non-routine problems
communicate effectively with team/work group and supervisors
complete workplace records quality and reports.
Evidence of Knowledge
Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate independently and to solve routine and non-routine problems, including knowledge of:
common moulding processes that require use of patterns and function and operating principles of the moulding equipment
influence of polymer type on pattern requirements
moulding process variables that affect pattern development
types and application of pattern mediums and materials
factors which may affect pattern quality and appropriate remedies
routine and non-routine problems that may arise, the range of possible causes and appropriate actions
organisation procedures relevant to the work environment/job role
hierarchy of control
hazards that may arise in the job/work environment and:
their possible causes
potential consequences
appropriate risk controls.
Assessment Conditions
The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
Where the assessee does not currently possess evidence of competency in MEM09002B Interpret technical drawing, it may be co-assessed with this unit.
The collection of performance evidence is best done from a report and/or folio of evidence drawn from:
a single project which provides sufficient evidence of the requirements of all the elements and performance criteria
multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria.
A third-party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team.
Assessment should use a real project in an operational workplace. Where this is not possible or where personal safety or environmental damage are limiting factors assessment must occur using a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment in a simulated environment should use evidence collected from demonstration of skills and one or more of:
walk-throughs
pilot plant operation
industry-based case studies/scenarios
‘what ifs’.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
In addition the assessor or anyone acting in subject matter expert role in assessment shall demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they shall assess with a subject matter expert who does meet these requirements.
Technical competence can be demonstrated through one or more of:
relevant VET or other qualification/Statement of Attainment
appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
Currency can be demonstrated through one or more of:
being currently employed undertaking the type of work being assessed
being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
conducting on the job training/assessments of the type of work being assessed
being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work.
Foundation Skills
This section describes those required skills (language, literacy and numeracy) that are essential to performance.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
Range Statement
This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. | |
Regulatory framework | The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used. Applicable legislation, regulations, standards and codes of practice include: health, safety and environmental (HSE) legislation, regulations and codes of practice relevant to the workplace, manual handling and hazardous materials Australian/international standards relevant to the materials being used and products being made any relevant licence and certification requirements. All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and such requirements the legislative requirements take precedence. |

Hazards | Hazards must be identified and controlled. Identifying hazards requires consideration of: eye strain repetitive strain injury posture hazards hazardous products and materials flammability other hazards that might arise. |
Problems | Routine and non-routine problems must be resolved. Non-routine problems must be resolved by applying operational knowledge to develop new solutions, either individually or in collaboration with relevant experts, to: determine problems needing action determine possible fault causes develop solutions to problems which do not have a known solution follow through items initiated until final resolution has occurred report problems outside area of responsibility to designated person. Non-routine problems are unexpected problems or variations of previous problems and include one or more of: stability of pattern in use damage to pattern in use emergency situations intermittent faults.
