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 equipmentand may include:instructions for the environmental monitoring of work and proceduresenvironmental care requirements relevant to the work |
Appropriate personnel may include: | supervisorssuppliersclientscolleaguesmanagers |
Blades may include: | wide band saw blades used for processing timber productsnarrow band saw blades used for cutting both ferrous and non-ferrous materials |
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 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 wheelsand 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 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 |
Teeth are to include: | sharpness of each toothdamage to teethpitch 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 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 atmust 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 profilesrates are generally measured in teeth per minute |
Pre start-up checks | are conducted to ensure:machine has been set-up correctlysystems are performing accurately 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 sawnchanges in line with sawing speeds, saw blade specifications, the material being sawn and direction of the sawing process |
Disposing of may include: | recycling band saw blades that cannot be sharpened or are damaged in the processre-using band saw blades that cannot be sharpened or are damaged in the process |
