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 and align blades and knives in line with 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 and aligning blades and knives

following organisational policies and procedures relevant to sharpening and aligning blades and knives

removing and replacing babbitts and set screws in line with standard operating procedures and machine settings

pouring babbitts to site procedures and finishing standard

removing and replacing set screws in line with site procedures and machine requirements

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

and may also include:

instructions for the environmental monitoring of work and procedures

environmental care requirements relevant to the work

Appropriate personnel may include:

supervisors

clients

colleagues

managers

Sharpening

is the angle, depth of cut, and speed that the knife or blade passes over the grinding wheel to obtain a sharp edge and required surface finish

Equipment 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

and may include:

grinding machines and babbitt making equipment, such as melting pots

Alignment

is the process of setting blades or knives so that all blades and knives sit at the same angle and height in relation to the abrasive wheel

verbal and non-verbal language

constructive feedback

active listening

questioning to clarify and confirm understanding

use of positive, confident and cooperative language

is the assembly that houses the knife when positioned on the machine chuck during sharpening

Pre-startup checks

are conducted to ensure:

with or without automatic feed

Wheel speed

is the speed at which the grinding wheel rotates - too fast and it may burn the metal, too slow and it may produce a rough finish or grab the knife or blade

Coolant

is used in conjunction with grinding operations to cool the metal blade or knife as it generates heat from the sharpening process

Burrs

are thin raised sections of metal that extend from the cutting edge

must be removed through a honing process before the knife or blade commences cutting
