Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Work holding fixtures/devices are set on machine as required using standard operating procedures. 2.4. Tool offset or datum settings are identified/verified against job sheet using standard operating procedures. 2.5. Program is loaded, selected and verified in accordance with job instructions.
3. Conduct pre-start checks	3.1. Pre-start checks are undertaken to standard operating procedures. 3.2. Correct safety procedures are observed and all safety equipment is checked for correct operation.
4. Set machine	4.1. Machine is set/adjusted to meet operational requirements and specifications. 4.2. Production samples are checked for compliance with specifications using standard operating procedures.
5. Instruct machine operator	5.1. Operator is instructed, if necessary, ensuring that all safety procedures and devices are in place.
6. Replace worn/damaged tooling	6.1. Where appropriate, preset tools are replaced, tool offsets are adjusted or other corrective action is taken using standard operating procedures.

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE
This section describes the skills and knowledge required for this unit.
Required skills
Look for evidence that confirms skills in: reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents planning and sequencing operations checking and clarifying task related information mounting work holding fixtures/devices/tooling mounting preset tooling verifying tool offsets and/or datum settings against job sheets or instructions loading and verifying programs conducting pre-start checks following safety procedures checking safety features and safety equipment for correct operation performing numerical operations and calculations/formulae within the scope of this unit setting and adjusting machines measuring and verifying first-off samples instructing machine operators on the sequence of operations identifying worn or damaged tooling and taking appropriate corrective action
Required knowledge
Look for evidence that confirms knowledge of: work holding fixtures/devices/tools and preset tooling for different machines/processes procedures for mounting work holding fixtures/devices/tools location of work holding fixtures/devices/tools relative to the machine datum or zero reasons for establishing tool offsets the purpose of datum settings the source(s) of information on tool offsets and datum settings procedures to locate and load programs procedures for verifying loaded programs pre-start checks safety features of the machine/process the purpose and function of safety features and/or safety equipment machine/process setting procedures machine operating procedures adjustments that can be made to the machine/process the effect of adjustments on machine and operational specifications product or part specifications in relation to the machining process measuring devices for checking parts or products examples of worn or damaged tooling the effects of worn or damaged tooling the corrective action for worn or damaged tooling hazards and control measures associated with numerical and computer controlled machines, including housekeeping safe work practices and procedures

Evidence Guide

EVIDENCE GUIDE
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 set computer controlled machines/processes. 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 setting computer controlled machines/processes 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 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

Range Statement

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.
