Unit Descriptor

Unit descriptor 

This unit covers setting work holding fixtures/devices/tools, setting tooling offsets, trialling the program, instructing the operator and replacing worn or damaged tooling.

Application of the Unit

Application of the unit 

The unit applies to any computer or numerically controlled machine or process. Applications may include NC/CNC machines and industrial robots.

Editing applies to identifying and accessing programs in edit mode in order to make changes associated with speeds, feed and operational sequence. Changes are generally made in situ.

Work is performed to established processes, practices and specifications. Machine operations may include welding, thermal cutting, metal cutting, forming and shaping etc.

All work and work practices are performed to instructions, plans and specifications as appropriate. Technical difficulties are resolved in consultation with appropriate technical advisers. Work is carried out autonomously to predetermined standards of quality and safety.

Where additional machining skills in excess of Unit MEM07005C (Perform general machining) are required then appropriate units should also be selected.

For setting and editing computer controlled thermal cutting machines, see Unit MEM05053A (Set and edit computer controlled thermal cutting machines)

Band: 

This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C7 (AQF level IV).

Unit Weight : 4

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.

Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

1. Identify job requirements

1.1. Instructions/plans are understood and correctly followed.

2. Set work holding fixtures/devices/tools

2.1. Correct ancillary devices are selected and attached to machine using standard operating procedures.

2.2. Machine is prepared to accept work holding devices.

2.3. Work holding fixtures/devices/tools are set to zero or a datum using appropriate setting devices.

3. Set tooling offsets

3.1. Tooling offsets are measured and recorded in machine controller.

4. Trial program

4.1. Machine is operated to produce first-off samples, observing all safety procedures.

4.2. First-off samples are checked for compliance with specifications.

4.3. Program editing to change speeds, feed and operational sequence requirements is undertaken as required to ensure job conforms to specification.

5. Instruct machine operator

5.1. Operator is instructed if necessary ensuring that all safety procedures and devices are in place.

6. Replace worn or damaged tooling

6.1. Where appropriate, 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

  • measuring devices/ techniques for checking the parts or product
  • effects of changes to cutting feeds and speeds
  • the impact of changes to the sequence of operations on the part or product to be produced
  • procedures for editing programs via the machine controller
  • the sequence of operations of the machine/process
  • examples of worn or damaged tooling
  • the effects of worn or damaged tooling
  • the corrective action to be taken for worn or damaged tooling
  • hazards and control measures associated with 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 and edit 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. Where assessment occurs off the job, i.e. the candidate is not in productive work, 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 and editing 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 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.

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.
