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 up and use single and multi-headed automated thermal cutting machines. 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 performing automated thermal cutting 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

Required skills

Look for evidence that confirms skills in:

setting up materials and machines

using thermal cutting machines

reading and interpreting routine information on written job instructions, specifications and standard operating procedures

following oral instruction

Required knowledge

Look for evidence that confirms knowledge of:

material set-up procedures.

advantages of stack cutting and nesting

procedures for establishing machine datum

hazards associated with igniting cutting media

safety precautions to be taken when starting and shutting down the machine.

procedures for using powder marking and other tracing devices.

use and application of personal protective equipment for automated thermal cutting

safe work practices and procedures

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.

Material

Ferrous and non-ferrous

Cutting medium

Includes fuel gases, oxy acetylene, plasma arc, laser etc.

Machine

Single or multi-headed machines including NC driven equipment etc.

Correct program

Programs on numerically controlled (NC) machines are selected and loaded according to predetermined instructions

Tracing devices

Powder marking and magnetic, photoelectric tracing devices
