REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

• collect, organise and understand information related to work orders, basic plans, and safety procedures
• communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with work supervisor, other workers and customers, and the reporting of work outcomes and problems
• plan and organise activities, including the preparation and layout of the work area 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, calculate quantities and estimate material requirements
• use pre-checking and inspection techniques to anticipate cutting problems, avoid re-working and wastage
• use the workplace technology related to the operation of CNC machines, including programs, development of computer applications within the industry and precision measuring devices

Required knowledge 

• workflow in relation to the operation of CNC machines
• identification of machines, processes and procedures
• procedures for reporting materials, product or equipment faults
• characteristics of materials used and uses of products produced
• workplace safety system requirements related to the operation of CNC machines

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.

Critical aspects of evidence 

• Identify and operate CNC machine, including the use of safety cut outs and guards
• Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment, safety and environmental protection equipment
• Interpret work order and locate and apply relevant information to set up, operate, adjust and monitor equipment used to produce components for picture frames.
• Follow work instructions, operating procedures and inspection practices to:

• minimise the risk of injury to self and others
• prevent damage to goods, equipment and products
• maintain required production output and product quality

• As a minimum, in flat, traditional and reverse profiles (all 3), set up and demonstrate the operation of EITHER:

• CNC mat board cutter in cutting the following patterns:

• single and double
• regular, oval, custom/regular
• multi-holed; AND/OR

• CNC mitre saws and CNC V-nailers to cut and join the following frames (at least one of them being a multi-angle frame) up to a width of 100 mm

• synthetic
• timber
• aluminium

• Work effectively with others
• Modify activities to cater for variations in workplace contexts and environment

Resource implications 

CNC machines, standard operating procedures, unprocessesd materials and appropriate work area.

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 which form a part of the job role.

Context of assessment 

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

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.

Unit scope 

This unit covers work involved in the set up, operation, adjustment and monitoring of computer numerical controlled (CNC) machines used in the production of picture frame components such as mat boards and frame mouldings and the joining of frames.
