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

Required Skills

Required skills

Required skills include reading and interpreting routine information on written job instructions specifications and standard operating procedures which 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

Required knowledge includes reasons for selecting the chosen sequence of operations methods of work holding basic marking out techniques including datum pointslines 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 and shields tolerances and 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

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 general machining including responsibility for selecting and mounting tooling and setting machining parameters 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 apply the skills covered in this unit of competency in new and different situations and contexts Critical aspects of assessment and evidence include correct job planning including identifying job requirements from drawings instructions or specifications and sequence of operations identifying any required tooling measuring equipment and accessories selecting and mounting required tooling selecting material and marking out if required setting machining parameters checking machined components for conformance to specifications
Context of and specific resources for assessment	This unit has been developed to support training in and recognition of trade level competency in general machining as applied to a trade level fitting and machining other trade or senior operator work environment Assessment should emphasise a workplace context and procedures found in the candidates workplace 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
Method of assessment	Typically Engineering Tradespersons Mechanical and other persons engaged in general machining work are required to apply their machining skills and techniques across a range of jobs and specifications A single assessment event is not appropriate On the job assessment should be included as part of the assessment process wherever possible Where assessment occurs off the job judgement must consider evidence of the candidates performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit 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
Guidance information for 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 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
