Elements and Performance Criteria

1. Observe safety precautions
   • Correct safety procedures are observed, and protective clothing and safety glasses are worn.
2. Determine job requirements
   • Drawings are interpreted, the sequence of operations is determined and tooling is selected to produce component to specification.
   • Cutting parameters are determined.
3. Perform milling operations
   • Milling operations are carried out to produce components to specification.
   • Operations are undertaken using conventional and/or climb milling techniques and a variety of cutters including slab, gang, end, shell, slot, form, slitting.
   • The full range of standard accessories is used including dividing heads and rotary tables as required.
4. Check components for conformance to specification
   • Component is checked for conformance to specification using appropriate techniques, tools and equipment.

Required Skills

Evidence Required

The evidence guide specifies the evidence required to demonstrate achievement in the unit of competency as a whole It must be read in conjunction with the unit descriptor performance criteria range statement and the assessment guidelines for the Metal and Engineering Training Package
Overview of assessment requirements	A person who demonstrates competency in this unit must be able to perform milling operations Competency in this unit cannot be claimed until all prerequisites have been satisfied
Context of 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
Interdependent assessment	This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with milling 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
Consistency of performance	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
Required skills	Look for evidence that confirms skills in
	setting up jobs using appropriate equipment
	calculating and setting cutting feeds and speeds appropriate to the job
	interpreting drawings and job instructionsspecifications
	milling components to specification
	visually and dimensionally checking components for conformance to specification
Required knowledge	Look for evidence that confirms knowledge of
	safety hazards associated with milling machines
	sequence of operations to achieve the job requirements
	cutter types and tooling geometry
	consequences of varying speeds and feeds from the optimum rates calculated
	effects of different materials on cutting speeds and feeds
	conventional and climb milling techniques and their applications
	the application of each of the following slab gang shell slot form and slitting
	applications requiring the use of dividing heads and rotary tables when milling components
	the procedures for using dividing heads and rotary tables on milling machines
	appropriate techniques tools and equipment to measure milled components
	use and application of personal protective equipment
	safe work practices and procedures

Range Statement

The range statement provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here. The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable
Variable	Scope
Drawings	Engineering drawings to AS 1100/1102
Tooling	Slab, gang, end, shell, slot, form, slitting cutters
Cutting parameters	Setting up machine, feed and speed calculations
Accessories	Dividing heads and rotary tables
