Elements and Performance Criteria

1. Observe safety precautions
   • Correct safety procedures are observed and protective clothing and safety glasses worn.
2. Determine job requirements
   • Drawings are interpreted, sequence of operations determined and tools selected to produce component to specification.
   • Cutting parameters are determined.
3. Perform precision shaping operations
   • Precision shaping operations are carried out including precision flat surfaces, shoulders, slots, keyways, angles and dovetails.
4. Perform precision planing operations
   • Precision planing operations are carried out including horizontal and vertical surfaces and angles.
5. Perform precision slotting operations
   • Precision slotting operations are carried out including feathered and tapered keyways, slotting internal cavities, dovetails, slotting circular surfaces and internal splines.
6. Check component for conformance to specification
   • Component is checked for conformance to specification using appropriate techniques, tools and equipment.

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 perform precision shapingplaningslotting operations 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 performing precision shapingplaningslotting operations 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.
Tools	Cutting tools, tool holders
Cutting parameters	Feeds, speeds, depth of cut, length of cut etc.
Precision operations	The use of dedicated precision measuring instruments
