Required skills include: |
collecting, organising and understanding information related to work orders, basic plans and safety procedures using communication skills to the level required to confirm work requirements and specifications; communicate effectively regarding work requirements with supervisors, other workers and customers; report work outcomes and problems; and to relate to people from a range of social, cultural and ethnic backgrounds, and of varying physical and mental abilities using literacy skills to the level required to understand information related to work orders, including common industry terminology, plans and safety procedures; prepare reports; and interpret technical information and specifications planning and organising activities, including the preparation and layout of the work area, and the obtaining of equipment and materials to avoid any backtracking, workflow interruptions or wastage working with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity using mathematical ideas and techniques to correctly complete measurements, calculate area and weight, estimate glass requirements and minimise waste using pre-checking and inspection techniques to anticipate processing problems, and avoid re-working and wastage using the limited workplace technology related to the processing of glass by basic machines, including handling aids, tools, equipment, calculators and measuring devices |
Required knowledge includes: |
the qualities and characteristics of glass, including hazards and handling requirements workplace safety system requirements related to glass processing by basic machines identification of glass processing equipment, including functions and procedures the set-up and operation of glass processing equipment, including procedures for reporting machine/product defects or equipment faults workflow requirements in relation to glass processing |
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. | |
Overview of assessment | Assessment processes and techniques must be culturally appropriate and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently: 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 AS/NZS 4667:2000 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 as a minimum: identify and use AS/NZS 4667:2000 Quality requirements for cut-to-size and processed glass complete straight cuts, truncated and radius corners, circles and fan holes, and pay holes by basic cutting machine in glass up to 7 mm in annealed, and laminated glass up to 1.0 m2 cut up to 7 mm annealed and laminated glass using a diamond saw arrise, grind and polish flat, round and mitre edges on up to 7 mm annealed, and laminated glass up to 0.5 m2 drill holes with tungsten or diamond drill bits in up to 7 mm annealed, and laminated glass up to 0.5 m2 calculate the cost of glass and edgework work effectively with others modify activities to cater for variations in workplace contexts and environment. |
Context of and specific resources for assessment | The application of competency is to be assessed in the workplace or realistically simulated workplace. Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian Standards requirements. The following resources should be made available: glass sheet/product up to 7 mm thick processing facilities/equipment (such as basic cutting and edging machines) table work area work orders appropriate safety and personal protection equipment. |
Method of assessment | Assessment must satisfy the endorsed Assessment Guidelines of the LMF02 Furnishing Industry Training Package. Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge. Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application. Assessment may be applied under project-related conditions (real or simulated) and require evidence of process. Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances. Assessment may be in conjunction with assessment of other units of competency. |
