Elements and Performance Criteria

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

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, supervisor's 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 instructions/specifications
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
