Application

This unit of competency defines the skills and knowledge required to manufacture split patterns.

It applies to the manufacture of split patterns for complex casting that require multiple pattern pieces. Construction includes wood, metal, polymer and composite materials

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

planning the appropriate pattern by identifying and interpreting specifications other applicable reference documents in determining type of pattern required

selecting appropriate materials and applying moulding or casting techniques and foundry processes suited to the type of split pattern required

calculating pattern parameters to develop split patterns

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

designing and manufacturing jigs and fixtures as required

manufacturing pattern on at least two occasions by marking out material for construction, producing pattern or pattern components to size and shape utilising appropriate hand and power tools

joining and fixing pattern component parts on at least two occasions and checking final product for 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, epoxy resin and composite products including features, characteristics and applications

moulding and casting techniques for split patterns

tooling required for casting and moulding

methoding techniques

use and application of jigs and fixtures

methods of construction

techniques, tools and equipment to measure, mark out and produce split patterns

mathematical calculations and formulae required to manufacture patterns or core boxes including those related to contraction, taper, pitch, profiles, 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 split 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.
