Overview of assessment

A person who demonstrates competency in this unit must be able to provide evidence that they can safely and efficiently maintain wide band saw blades and gang saws within organisational requirements

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

The evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements of this unit and include demonstration of

following applicable Commonwealth State or Territory legislative and regulatory requirements and codes of practice relevant to maintaining wide band saw blades

following organisational policies and procedures relevant to maintaining wide band saw blades

maintaining wide band and gang saw blades in line with work order and within prescribed organisational requirements

removing and replacing saws from equipment

assessing saw conditions in line with standard operating procedures

Context of and specific resources for assessment

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 required knowledge other than confirmatory questions will usually be conducted in an offsite context

Assessment is to follow relevant regulatory or Australian Standards requirements

The following resources should be made available

workplace location or simulated workplace

materials and equipment relevant to undertaking work applicable to this unit

specifications and work instructions

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the FPI Training Package

Assessment must satisfy the endorsed Assessment Guidelines of the FPI11 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 required knowledge

Assessment must be by direct observation of tasks with questioning on required knowledge and it must also reinforce the integration of employability skills

Assessment methods must confirm the ability to access and correctly interpret and apply the required knowledge

Assessment may be applied under projectrelated 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

The assessment environment should not disadvantage the candidate

Assessment practices should take into account any relevant language or cultural issues related to Aboriginality gender or language backgrounds other than English

Where the participant has a disability reasonable adjustment may be applied during assessment

Language and literacy demands of the assessment task should not be higher than those of the work role

Patterns are to include:

methods which use hammers or rolls to remove defects evenly and without affecting the opposing side

Curvature

is the distance or chord height measured when the centre of the blade falls away as a result of an elongating inner zone

chord height 'tension drop' is generally measured with a tension gauge having a curvature that suits blade width, thickness, and production conditions

Tensioning

is the process of using mechanically driven rolls to compress and elongate certain sections of the inner zone of a blade; compression of the inner zone places the outer edges of the blade in tension

artificially stiffens the cutting edge and reduces the influence of sawing forces that cause buckling of the cutting edge and lateral instability

Welding jigs

are jigs or benches which hold the saw and/or teeth in place securely to allow welding to occur

'benches' incorporate anvils and clamps to lock the blade into welding position
