AS4667 Quality requirements for cut to size and process 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 with semi-automatic or automatic machines
Apply safe handling requirements for machines, equipment, products and materials, including use of personal protective equipment
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:

process and upload computerized cutting data from optimisation software programs
load and position stock sheets onto semi-automatic and automatic cutting tables
perform pre-cutting tool and machinery checks
cut given dimensions from stock sheets with minimal wastage/off-cuts
cut shapes from optimisation data
remove, pack and store cut glass including labelling for despatch
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 semi-automatic and automatic machines
Identification of semi-automatic and automatic glass processing machines, including their functions and procedures
The set up and operation of semi-automatic and automatic glass processing machines 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 developing workplace technology related to the processing of glass by semi-automatic and automatic machines including computers, handling aids, tools and equipment

Resource Implications
Semi-automatic, automatic or computerised glass processing equipment, optimisation software programs, work area, standard operating procedures, work orders, unprocessed materials 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 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
