Elements and Performance Criteria
|
Elements describe the essential outcomes.
|
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions.
|
|
1. Prepare for sharpening
|
1.1 Review work order and where required check with appropriate personnel.
1.2 Select appropriate repair, maintenance and personal protective equipment and check for operational effectiveness in line with manufacturer's recommendations.
1.3 Plan sharpening process in line with work order and site procedures.
|
|
2. Assess condition and set up sharpening equipment
|
2.1 Follow organisational safety procedures thoughout all maintenance and repair processes.
2.2 Assess cutting performance of blade and determine need to replace or sharpen.
2.3 Assess prior repairs and condition of teeth, set, and straightness of blade.
2.4 Select sharpening machine with suitable wheel diameter and thickness and change, profile or grind wheel in line with manufacturer’s instructions.
2.5 Adjust machine settings to suit required tooth profile geometry, blade set or kerf, blade thickness and diameter to manufacturer's recommendations.
2.6 Set up saw in grinder with appropriate attachments for tooth pitch.
|
|
3. Sharpen circular saw blade
|
3.1 Grind teeth face and gullet to achieve required sharpness and surface finish.
3.2 Maintain tooth profile to industry standards.
3.3 Keep variations in tooth height within industry or manufacturer tolerances for concentricity.
3.4 Control wheel and saw hand feeds to minimise wear, avoid burn marks and maintain smooth surface finish.
3.5 Identify damaged and exhausted circular saw blades and dispose of these in line with organisational procedures and environmental protection practices.
3.6 Identify routine processing and equipment faults and resolve or report to appropriate personnel.

Replaces equivalent unit FPISAW3208B Sharpen circular saws, which was first released with FPI11 Forest and Forest Products Training Package Version 2.2. This is the first release of this unit in the new standards format.
Assessment requirements now specify the performance and knowledge evidence, as well as assessment conditions for this unit of competency. These sections simplify and replace components used in the previous unit format, including Required Skills and Knowledge, Evidence Guide and Range Statement
|
Performance Evidence
A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit. If a specific volume or frequency is not stated below, then evidence must be provided that the following requirements have been performed on at least one occasion:
- follow organisational policies and procedures relevant to sharpening circular saws
- remove and replace circular saw blades from equipment
- sharpen circular saw blades in line with an individual work order for each job
- assess cutting performance as follows:
- saw performance balanced against achievement of required production time
- degree of deviation in the range of sawn products
- assess the condition of blade teeth for:
- sharpness of tooth cutting edges
- angles within the tooth profile
- tooth strength
- damage to teeth
- pitch
- depth
- number of teeth per metre
- operate the abrasive wheel at appropriate speed to remove material without affecting steel characteristics
- produce a quality of surface texture left by the abrasive wheel along the entire profile and at the intersection of all cutting edge angles.
Knowledge Evidence
A person competent in this unit must be able to demonstrate knowledge of:
- purpose, features and operation of circular saws for which blades are sharpened
- features and names of different parts of circular saw blades
- purpose, features and operation of tools and equipment used to sharpen circular saw blades:
- gulleting and grinding machines
- abrasive wheels
- importance of sharpening and setting teeth and tension to match requirements for:
- characteristics of various materials sawn
- speed of the sawing process
- direction of the sawing process
- cutting angle for sawing
- saw blade specifications
- removing saw blades from circular saws
- assessing saw blade condition
- sharpening blades to specified requirements
- setting teeth to a specified profile
- setting concentricity of teeth
- tooth pitch and tooth angles at which blades are sharpened (blade geometry)
- range of speeds at which abrasive wheels can be operated without damaging blades
