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. |

Sharpening is to include: | the amount of material removed from the tooth profilethe ability to produce the required profilethe speed at which the abrasive wheel can remove material without affecting steel characteristicsthe quality of surface texture left by the abrasive wheel along the entire profile and at the intersection of all cutting edge angles |
Work order is to include: | instructions for the sharpening of circular saw blades in designated equipmentand may include:instructions for the environmental monitoring of work and proceduresenvironmental care requirements relevant to the work |
Appropriate personnel may include: | supervisorssuppliersclientscolleaguesmanagers |
Equipment may include: | gulleting and grinding machinesmachine attachmentshand-held toolsabrasive wheels and is to include:procedures for equipment lock-out, i.e. protecting operators and co-workers from accidental injury by isolating the machine from the power source |
Communication may include: | verbal and non-verbal languageconstructive feedbackactive listeningquestioning to clarify and confirm understandinguse of positive, confident and cooperative languageuse of language and concepts appropriate to individual social and cultural differencescontrol of tone of voicebody language |
Cutting performance is to include: | saw performance balanced against achievement of required production time degree of deviation in the range of sawn products |
Blades may include: | circular cross cut blades used for cutting timber products rip saw blades used for cutting timber products |
Teeth are to include: | sharpness of tooth cutting edgesangles containing within the tooth profiletooth strengthdamage to teethpitchdepthand number of teeth per metre |
Set | is the distance cutting edge points extend from the blade surface (or plane) to provide the blade clearance from the material being sawnin wide bandsaw blades is achieved by swaging and shaping, or tipping tooth pointsin narrow bandsaw blades applied to, for example, alternate spring set and wave set to provide clearance |
Straightness | is the assessment of blade level and flatness against a straight edge or plumb line when blade is in a vertical position |
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 |
Pitch | is the distance between the tips of the teeth on the saw blade |
Pre start-up checks | are conducted to ensure:machine has been set-up correctlysystems are performing accurately machinery is operating to optimum performance |
Face | is the front of a tooth along which the angle of hook or rake is measuredon square ground rip saws, the tooth face is parallel to the surface of the material being sawn |
Gullet | is the hollow area between tooth points |
Profile | is the shape or outline of the teeth designed to suit the characteristics of the materials being sawnchanges in line with sawing speeds, saw blade specifications, the material being sawn and the direction of the sawing process |
Concentricity | is sharpening blades so that each tooth point on a round saw is at the same radius from the centre of the saw bladeis critical to prevention of blade vibration - when tooth points are at different radii from the blade centre the saw is 'out-of round' or non-concentric |
Disposing of may include: | recycling circular saws that cannot be sharpened or are damaged in the processre-using circular saws that cannot be sharpened or are damaged in the process |
Records and reports may include: | the blade typesizeinspectiongrading and labelling outcomesstorage locationsquality outcomeshazardsincidentsequipment malfunctionsand may be:manualusing a computer-based system another appropriate organisational communication system |
