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 blades and knives 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.
1.3 Plan sharpening and aligning process in line with work order.
|
|
2. Assess condition and set up blade and knife assemblies
|
2.1 Follow organisational safety procedures and manufacturer’s recommendations throughout all repair and maintenance processes.
2.2 Remove blade or knife for sharpening from designated machinery.
2.3 Assess cutting performance of blade or knife to determine sharpening requirements.
2.4 Assess condition of knife holder, jig and chuck and correct defects.
2.5 Clean and secure knife holder to chuck in line with organisational procedures.
2.6 Select jig type and setting for required blade or knife setup.
|
|
3. Set up equipment
|
3.1 Clean blades or knives of excess build-up, inspect babbitts for defects and replace where unserviceable.
3.2 Select angle for sharpening blade to suit its use in specified equipment.
3.3 Set up grinder with suitable attachment for holding knife or blade and examine and dress grinding wheel.
3.4 Select grinding wheel speed and feeds to suit blade or knife, grinding wheel material and configuration.
|
|
4. Operate grinder to sharpen blades and knives
|
4.1 Feed grinding wheel across and into cutting edge to sharpen blade to geometric requirements without defects or burns.
4.2 Monitor grinder for operational effectiveness and apply coolant as required.
4.3 Inspect blade or knife after sharpening for accuracy and hone remaining burrs to obtain sharp cutting edge.
4.4 Dispose of unserviceable and damaged blades and knives in line with environmental protection practices.
|
|
5. Align blades and knives
|
5.1 Inspect babbitts to assess reconditioning requirements.
5.2 Heat babbitt material to required pouring temperature.
5.3 Set up blade or knife in pouring jig to required dimensions.
5.4 Pour babbitt without to minimise material waste and avoid cavities and shrinkage.
5.5 Cool assembly and remove excess material to allow correct positioning in machinery.
5.6 Inspect set screws and replace bent or broken screws.
5.7 Adjust set screws to position knife or blade at correct depth and lock into position to avoid knife or blade movement.
5.8 Record and report processing problems and equipment faults to appropriate personnel.
