Information and procedures
Machine manufacturers' specifications and operational procedures
Workplace procedures relating to the setting and operation of glass cutting, drilling and edging machines
Work instructions, including job sheets, cutting lists and plans
Safety standards include personal protective equipment, OH&S regulations and enterprise requirements
AS4667 Quality requirements for cut to size and processed glass

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
Interpret work orders and plan processing operations
Identify the materials, patterns/plans, processes, machines, equipment and settings to undertake a glass cutting, drilling, shaping and/or edging task by basic machines
Apply safe handling requirements for machines, equipment, products and materials, including use of personal protective equipment
Apply AS4667 Quality requirements for cut to size and processed glass
Set up for and prepare to process glass

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
To complete a minimum of:
identification and use of AS4667 Quality requirements for cut to size and processed glass
straight cuts, simple shapes, truncated and radius corners, circles, fan holes, pay holes and ovals in glass up to 6 mm annealed and 6.38 mm laminated glass up to 1.0 m 2
cut 6 mm annealed and 6.38 mm laminated glass using a diamond saw
arris, grind and polish flat, round and mitre edges on 6 mm annealed and 6.38 mm laminated glass up to 0.5 m 2
Drill holes with tungsten and diamond drill bits in 6 mm annealed and 6.38 mm laminated glass up to 0.5 m 2
calculate the cost of glass and edgework
Work effectively with others
Modify activities to cater for variations in workplace contexts and environment

Underpinning Knowledge
The qualities and characteristics of glass, including the hazards and handling requirements
Workplace safety system requirements related to glass processing by basic machines
Identification of glass processing equipment, including its functions and procedures
The set up and operation of glass processing equipment including procedures for reporting machine/product defects or equipment faults
Workflow in relation to glass processing

Underpinning Skills
Information. Collect, organise and understand information related to work orders, basic plans, and safety procedures
Communication. Communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with 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 work area 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, calculate area and weight, estimate glass requirements and minimise waste
Solve problems. Use pre-checking and inspection techniques to anticipate processing problems, avoid reworking and avoid wastage
Use of technology. Use the limited workplace technology related to the processing of glass by basic machine including handling aids, tools, equipment, calculators and measuring devices

Resource Implications
Glass sheet/product, processing facilities/equipment (such as basic cutting and edging machines), table, work area, work orders and appropriate safety and personal protection equipment.

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 may be in conjunction with assessment of other relevant units of competency.

Context of Assessment
Assessment may occur on the job or in a workplace simulated facility with relevant glass processing machines, 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
