Elements and Performance Criteria

The Range Statement provides advice to interpret the scope and context of this unit of competency, allowing for differences between enterprises and workplaces. It relates to the unit as a whole and facilitates holistic assessment. The following variables may be present for this particular unit:

CNC machining and processing centres are to include three axis machining centre and may include:
multi-tasking machining centres
flat-bed routers and mortiser

Material to be machined and processed is to include:
solid timber and manufactured board

Unit scope

Work involves reading and interpreting drawings, selecting and installing tooling, setting jigs and fixtures, programming skills (sub-programs and parametrics), performance of CAM functions, downloading and storage of data to complete detailed profiling and other specified operations

Unit context

OH&S requirements include legislation, building codes, material safety management systems, hazardous substances and dangerous goods code and local safe operating procedures

Work is carried out in accordance with legislative obligations, environmental legislation, relevant health regulations, manual handling procedures and organisation insurance requirements

Work requires individuals to demonstrate some discretion, judgement and problem solving skills in the set up and operation of machining and processing centres

Competency may be demonstrated in workplaces involved in the manufacture of solid timber furniture, domestic furniture, commercial furniture, kitchen and bathroom cabinets and/or furniture components

Tools and equipment are to include:
stand-alone or integral computing systems and machine-specific tools

Personal protective equipment

Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices

Information and procedures

Workplace procedures relating to the use of tools and equipment

Work instructions, including job sheets, cutting lists, plans, drawings and designs

Workplace procedures relating to reporting and communication

Manufacturers' specifications and operational procedures

The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competency for this unit. This is an integral part of the assessment of competency and should be read in conjunction with the Range Statement.
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 machining and processing centre equipment to complete detailed profiling, including:
development and application of sub-program
development and application of parametric program, and
application of CAD/CAM functions
Conduct operator maintenance on the machining and processing centre equipment
Work effectively with others
Modify activities to cater for variations in workplace contexts and environment

Underpinning Knowledge
Types, characteristics, uses and limitations of CNC machining and processing centres
CNC theory, practices and techniques
Characteristics of materials used and uses of products produced
Workflow processes
Procedures for reporting materials, product or equipment faults

Underpinning Skills
Information. Collect, organise and understand information related to CNC machining and processing centre operations, work orders, plans and safety procedures
Communication. 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
Planning. 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
Teamwork. Work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
Mathematical ideas and techniques. Use mathematical ideas and techniques to correctly complete measurements, compute input data and estimate material requirements
Solve problems. Use pre-checking and inspection techniques to anticipate CNC machining and processing centre problems, avoid reworking and avoid wastage
Use of technology. Use the workplace technology related to CNC machining and processing centre, including machining and processing, tools, equipment and measuring devices

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.

Key Competency Levels
NB:These levels do not relate to the Australian Qualifications Framework. They relate to the seven areas of generic competency that underpin effective workplace practices.
There are three levels available:
Level 1 where work is within set conditions and process
Level 2 where the management or facilitation of conditions or process is exercised; and
Level 3 where the design and/or development of conditions or process is required
Communicating ideas and information

Collecting analysing and organising information
(2)

Planning and organising activities
(2)

Working with others and in teams
(1)
