Elements and Performance Criteria

1. Determine job requirements
   • Drawings, instructions and specifications are interpreted and understood.
2. Determine sequence of operations
   • Sequence of operations including job set-up is determined for maximum efficiency and to meet job specifications.
   • Appropriate material is selected and datum established as required.
3. Select and mount tools
   • Appropriate tools for job are selected, sharpened and shaped as required.
   • Tools are mounted and positioned correctly.
4. Perform machining operations
   • Basic marking out techniques are used where required.
   • Machining parameters are set for job requirements and maximum tool life.
   • Work is held or correctly clamped without damage to product, and all safety requirements are met.
   • Machining is performed in a safe manner utilising all guards, safety procedures and personal protective clothing and equipment.
5. Measure components
   • Components are checked with instruments or gauges appropriate to the measurement requirements to ensure compliance with specifications.
6. Adjust and maintain machine
   • Routine maintenance and adjustments are carried out as required which may include slide and collar adjustment, cleaning and lubrication and the like.

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 general machining 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 performing general machining 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 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
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
	reading and interpreting routine information on written job instructions specifications and standard operating procedures May include drawings
	following oral instruction
	planning and sequencing operations
	preparing operational work plan
	sharpening and shaping cutting tools
	identifying worn or damaged cutting tools
	correct mounting and positioning of cutting tools
	basic marking out of materials
	setting machining parameters to achieve the job requirements and maximise tool life
	using appropriate and sufficient clampingmounting of the work piece
	using coolantlubricant correctly
	checking for conformance to specifications
	measuring to specified tolerances and dimensions
Required knowledge	Look for evidence that confirms knowledge of
	reasons for selecting the chosen sequence of operations
	methods of work holding
	basic marking out techniques including datum pointslines etc
	geometry of cutting tools for a range of materials and applications
	benefits of using correctly sharpened cutting tools
	machine operation
	selection of feeds and speeds to suit a range of materials and operations within the scope of this unit
	correct methods of mounting a variety of cutting tools
	safety issues with regard to correct clamping guards shields etc
	tolerances limits of size
	situations indicating the need for machine adjustment lubrication and cleaning
	techniques tools and equipment to measure materials and machined components
	use and application of personal protective equipment
	safe work practices and procedures
	hazards and control measures associated with general machining

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
Operations	Parallel cutting, slotting, planing, drilling, knurling, cutting flats, non-precision surface grinding operations etc.
Material	Ferrous and non ferrous
Tools	Cutting tools and accessories, measuring devices
Marking out techniques	Basic marking out techniques using calipers, steel rules, dividers, scribers etc.
Machining parameters	Speeds, feeds, stops, coolant and cutting lubricants etc. Machines include lathes, mills, planers, shapers, radial arm drills, slotters, surface grinder etc.
Maintenance and adjustments	Slide and collar adjustment, cleaning and lubrication
