Required skills

collect, organise and understand information related to CNC sizing operations, work orders, plans and safety procedures

communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems

plan and organise activities, including the preparation and layout of the worksite and the obtaining of equipment and materials to avoid any back tracking, workflow interruptions or wastage

work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity

use mathematical ideas and techniques to correctly complete measurements, compute input data and estimate material requirements

use pre-checking and inspection techniques to anticipate CNC sizing problems, avoid reworking and avoid wastage

use the workplace technology related to CNC sizing, including machinery, tools, equipment and measuring devices

Required knowledge

types, characteristics, uses and limitations of CNC sizing machines

CNC theory, practices and techniques

characteristics of materials used and uses of products produced

workflow processes

procedures for reporting materials, product or equipment faults

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.

Critical Aspects of Evidence

Locate, interpret and apply relevant information

Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

Identify materials used in the work process

Follow work instructions, operating procedures and inspection practices to:

minimise the risk of injury to self or others

prevent damage to goods, equipment or products

maintain required production output and product quality

Identify, set up and operate CNC sizing equipment, including the use of safety cut-outs and guards, to product a range of complex cutting patterns to its full potential

Conduct operator maintenance on the machine and related equipment

Work effectively with others

Modify activities to cater for variations in workplace contexts and environment

Resource Implications

CNC controlled equipment, standard operating procedures, unprocessed materials.

Method of Assessment

Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts.

Assessment should be by direct observation of tasks and questioning on underpinning knowledge.

Assessment should be conducted over time and may be in conjunction with assessment of other units of competency.

Context of Assessment

Assessment may occur on the job or in a workplace simulated facility with relevant process equipment, materials, work instructions and deadlines.

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.

CNC sizing machines

CNC sizing machines are to include CNC beam saws and may include double end profiling machines

Unit scope

Work involves computer programming skills, reading and interpreting drawings, stock control, setting cutting speeds, computer-aided machining operations, saw and tool maintenance

Material to be sized is to include:
