Elements and Performance Criteria

1. Identify and analyse defects in tooling
   • Defects are determined from any of: production components produced, production reports or tool inspections.
   • Sequence of maintenance operations is planned.
2. Disassemble and assess tooling components
   • Tooling is disassembled, and condition of components against prints, drawings, manufacturers' drawings etc. is assessed.
   • Worn/damaged parts are replaced/reconditioned.
3. Obtain and prepare replacement materials
   • Materials are obtained to meet tooling requirements.
4. Manufacture/repair tooling components
   • Appropriate hand and hand held power tools are selected and used.
   • Appropriate machining process is chosen from a range of standard tool room machines.
   • Machining parameters are set to produce components to specification.
   • Where appropriate, heat treatment is initiated according to specification.
5. Assemble tooling components
   • Using acceptable tool making techniques and procedures, tooling components are checked and assembled correctly in conformance with specifications.
6. Measure production components
   • Production components are checked with precision instruments to ensure conformance to specifications as required.
7. Identify potential production/maintenance problems
   • Conditions leading to tooling failure are identified and recorded.
   • Recurrent faults are identified and solutions are initiated.

Evidence Required

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 maintain tool and 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 tool and die maintenance 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 supervisors reports project work samples and questioning Questioning should not require language literacy and numeracy skills beyond those required in this unit 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

Range Statement

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.
