This competency covers the operation and adjustment of optical fibre drawing machines and the solving of non-routine problems.This competency is typically performed by advanced operators demonstrating some relevant theoretical knowledge and using a range of well-developed skills requiring some discretion and judgement.

Application

Application of this unit

This competency applies to operators who are required to apply knowledge of materials, product purpose and processes to the operation of optical fibre drawing machines. The key factors are the production of material meeting quality standards and product requirements and the recognition and resolving of a range of routine and non-routine problems.

Required Skills

This describes the essential skills and knowledge and their level required for this unit.

Application of knowledge of the materials, equipment and process sufficient to recognise material and equipment conditions which may lead to out of specification production.

Knowledge of organization procedures and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.

Application of the knowledge of managing risks using the hierarchy of controls applied to the optical fibre process. Application of approved hazard control, safety procedures, the use of PPE in relation to handling materials, equipment operation and cleanup.

Knowledge as a basis for solving processing and material problems, including:

products, materials and material characteristics

function of optical fibre drawing equipment, components and ancillary equipment

optical fibre drawing equipment and manufacturing processes

behaviour of materials in relation to speed, temperature and tension

impact of machine speed, tension and temperature during the production stages on product quality and output

changes to materials in optical fibre drawing process

waste management and importance of non-conforming materials

impact of variations in raw materials and equipment operation in relation to final product

changes to materials at various stages of production

waste management and importance of non-conforming materials.

Competence also includes the ability to:

plan own work, including predicting consequences and identifying improvements

make measurements when required and identify product out of specification

identify and describe own role and role of others involved directly in the fibre optic drawing making process

identify factors which may affect product quality or production output and appropriate remedies

identify when the operator is able to rectify faults and when assistance is required.

Language, literacy and numeracy requirements

This unit requires the ability to read and interpret typical product specifications, job sheets and material labels as provided to operators.

Writing is required to the level of completing workplace forms and production reports.

Basic numeracy is required, eg to determine how many 2 kg, 3 kg and 5 kg bags are needed to make up a requirement for 50 kg.

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the assessment guidelines for this training package.

Overview of assessment

A holistic approach should be taken to the assessment.

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:

identify critical materials properties and optical fibre drawing equipment characteristics in relation to the process requirements and the end product.

Consistent performance should be demonstrated. For example, look to see that:

production quality and output standards are met consistently

the process runs consistently and smoothly.

Assessment method and context

Assessment will occur on industrial optical fibre drawing equipment in a work-like environment.

Competence in this unit may be assessed:

using an appropriate, industrial optical fibre drawing machine

in a situation allowing for the generation of evidence of the ability to recognise, anticipate and respond to problems

by using a suitable simulation and/or a range of case studies/scenarios

through a combination of these techniques.

In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Specific resources for assessment

This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
