Unit Descriptor

Unit descriptor 

This unit covers preparing to manufacture and manufacturing cavity dies including matching use of hand and hand held power tools, assembly of the tooling components and trialling the tooling.

Application of the Unit

Application of the unit 

This unit includes the skills required to manufacture and trial all types of production tooling.

Work is undertaken autonomously or in a team environment.

The tooling being produced may include, but is not limited to, the following types:, forging dies, extruding dies, die casting (high and low pressure and gravity feed), plastic moulds (injection, compression, blow and foam) and glass moulds or dies requiring precision manufacture. A normal range of tool room equipment would be used which may include lathes, mills, copy/duplicator, grinders, EDM and wire cut equipment, precision measurement, hand and power tools.

Where simple welding or brazing skills are required, see Units MEM05012C (Perform routine manual metal arc welding) and Unit MEM05006B (Perform brazing and/or silver soldering). Where manufacture of press tools and gauges is required, unit MEM18014B (Manufacture press tools and gauges) should be selected.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

1. Prepare to manufacture cavity die

1.1. Tooling requirements are determined from customer's components drawings, prints or sample component.

1.2. Tooling type and design are conceptualised and planned with reference to customer's specifications (written or verbal) for numbers, finish, quality and material.

1.3. Production machine to be used to produce components is assessed and considered in tooling design.

1.4. Tool design is interpreted and visualised from tooling drawings, prints or plan and checked against customer requirements.

1.5. Selected production machine mounting requirements are determined to ensure any special or additional provisions are incorporated in tooling design.

2. Manufacture tooling

2.1. Appropriate materials are selected and obtained to meet tooling requirements for strength, durability, component finish, heat treatment qualities where necessary and accounting for materials availability.

2.2. Selected material is tested for hardness as appropriate to aid selection of machine tools, hand tools and hand held power tools to be used to fashion or shape tooling components.

2.3. Plan is developed to sequence and stage manufacturing process, including establishing datum, mark out, rough out (machine or fashion), stress relieve/heat treat, finish size, fashion and fit and assemble componentry.

3. Perform machining operations

3.1. Appropriate machines and machining process are selected from a range of standard tool room machines to shape/produce tooling components to specifications.

4. Use hand and hand held power tools

4.1. A range of hand and hand held power tools are selected and used to fashion/manufacture tooling components to specification.

4.2. Where practical, components sample or section is produced for testing.

5. Assemble tooling components

5.1. Using acceptable tool making techniques and procedures, components are checked and fitted/assembled correctly to specifications.

6. Trial tooling

6.1. First-off component is checked with precision instruments against specification.

6.2. Tooling is modified as necessary to produce components to specification.

6.3. Modified tooling is re-trialled and component is produced.

6.4. Conformance to specification is verified and reported according to standard operating procedures.

6.5. Where necessary, all deviations or modifications to original tooling design, prints or plans are recorded and reported according to standard operating procedures.

Evidence Guide

EVIDENCE GUIDE 

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 manufacture cavity dies. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

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, that is the candidate is not in productive work, then an appropriate simulation 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. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with cavity die manufacture or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment 

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment
