Application

This unit of competency defines the skills and knowledge required to develop and manufacture irregular joint wood patterns and irregular joint pattern component parts, including general engineering and master patterns.

It applies to wooden patterns, requiring irregular joints to meet the pattern specifications, Timber or timber laminate may be used to construct these patterns.

Where patterns are required to be set up on pattern plates, unit MEM04039 Assemble plated patterns should also be selected.

Where the development and manufacture of cast gear patterns is required, unit MEM04026 Develop and manufacture spur gear patterns should also be selected.

Where the development and manufacture of cast bevel gears is required, unit MEM04027 Develop and manufacture bevel gear patterns should also be selected.

Where the development and manufacture of cast chain gear and sprocket patterns is required, unit MEM04028 Develop and manufacture chain gear and sprocket patterns should also be selected.

Where the development and manufacture of cast conveyor screw patterns is required, unit MEM04029 Develop and manufacture conveyor screw patterns should also be selected.

Where the development and manufacture of cast marine propellers is required, unit MEM04030 Develop and manufacture propeller patterns should also be selected.

Where the selection and use of precision measurement is required, unit MEM12003 Perform precision mechanical measurement should also be selected.

This unit should not be selected when unit MEM18014 Manufacture press tools and gauges has already been selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting specifications to develop irregular joint wood patterns

determining type of irregular joint wood pattern required through application of moulding and/or casting techniques and selecting the appropriate timber or timber composites to meet requirements

preparing for manufacture of patterns using the appropriate mathematical calculations for angles, tapers, clearances and determination of contraction rates

laying out pattern to specifications on at least two occasions, showing tapers, machining allowances, core prints and method of construction

designing and manufacturing required jigs or fixtures

marking out and manufacturing irregular joint wood patterns and pattern component parts on at least two occasions, using appropriate hand and power tools

joining and fixing pattern components on at least two occasions and checking compliance with specifications

identifying pattern in accordance with SOPs.

Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

timber products including features, characteristics and applications

moulding and casting techniques for irregular joint wood patterns

tooling required for casting and moulding

methoding techniques

use and application of jigs and fixtures

methods of constructing irregular joint wood patterns

formulae and mathematical techniques required for manufacturing of patterns or core boxes including those related to contraction, taper, clearances and machining allowances

identification coding and numbering

pattern checking techniques

mouldability including surface finish, face taper, convex or concave perspectives and undercuts.

Assessment Conditions

Assessors must:

have vocational competency in the development and manufacture of irregular joint wood patterns at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires.

Where possible, assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions that cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications.

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.
