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

A person who demonstrates competency in this unit must be able to provide evidence that they can safely and efficiently sharpen band 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 sharpening band saws

following organisational policies and procedures relevant to sharpening band saws

sharpening band saws in line with the work order and within prescribed organisational requirements

removing and replacing band saw blades from equipment

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 off-site 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 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 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

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

Procedures for recording and reporting workplace information

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Work order is to include:

instructions for the sharpening of band saw blades in designated equipment

and may include:

instructions for the environmental monitoring of work and procedures

environmental care requirements relevant to the work

Appropriate personnel may include:

supervisors

suppliers

clients

colleagues

managers

Blades may include:

wide band saw blades used for processing timber products

narrow band saw blades used for cutting both ferrous and non-ferrous materials

Sharpening is to include:

the amount of material removed from the tooth profile

the ability to produce the required profile

the speed at which the abrasive wheel can remove material without affecting steel characteristics, and the quality of surface texture left by the abrasive wheel along the entire profile and at the intersection of all cutting edge angles

Equipment may include:

alternative sharpening machines and grinding wheels

and is to include:

procedures for equipment lock-out such as protecting operators and co-workers from accidental injury by isolating the machine from the power source

Communication may include:

verbal and non-verbal language

Cutting performance is to include:

saw performance balanced against achievement of required production time

degree of deviation in the range of sawn products

Teeth are to include:

Set

is the distance cutting edge points extend from the blade surface (or plane) to provide the blade clearance from the material being sawn

in wide bandsaw blades is achieved by swaging and shaping, or tipping tooth points

in narrow bandsaw blades applies to, for example, alternate spring set and wave set to provide clearance

Tension

is the level of stress or 'stiffness' induced at the cutting and back edges of the blade by compressing the blade along the inner zone

Dressing

involves cleaning or shaving the top surface of the grinding wheel to remove the build up of old sharpening metal and coolant and dull abrasive grains

Geometry

is the tooth pitch and the tooth angles that a blade is sharpened at

must match the type and characteristics of the material being sawn

Machine feed

is the speed at which the abrasive wheel on the sharpening machine or grinder moves in and out of the tooth profiles

rates are generally measured in teeth per minute

Pre start-up checks

are conducted to ensure:

machine has been set-up correctly

machine is operating to optimum performance

Testing

is the process of assessing a tooth after machine settings and grinding has been undertaken to check pitch and angle of the sharpening process

Profile

is the shape or outline of the teeth designed to suit the characteristics of the materials being sawn

changes in line with sawing speeds, saw blade specifications, the material being sawn and direction of the sawing process
