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. |
OHS requirements: | are to be in line with applicable Commonwealth, State or Territory legislation and regulations, and organisational safety policies and procedures, and may include: personal protective equipment and clothing safety equipment first aid equipment fire fighting equipment hazard and risk control fatigue management elimination of hazardous materials and substances safe forest practices including required actions relating to forest fire manual handling including shifting, lifting and carrying machine isolation and guarding |
Environmental requirements may include: | legislation organisational policies and procedures workplace practices |
Legislative requirements: | are to be in line with applicable Commonwealth, State or Territory legislation, regulations, certification requirements and codes of practice and may include: award and enterprise agreements industrial relations Australian Standards confidentiality and privacy OHS the environment equal opportunity anti-discrimination relevant industry codes of practice duty of care |
Organisational requirements may include: | legal organisational and site guidelines policies and procedures relating to own role and responsibility quality assurance procedural manuals quality and continuous improvement processes and standards OHS, emergency and evacuation procedures ethical standards recording and reporting requirements equipment use and maintenance and storage requirements environmental management requirements (waste minimisation and disposal, recycling and re-use guidelines) |
Work order is to include: | instructions for the sharpening of band saw blades in designated equipment and may include: instructions for the environmental monitoring of work and procedures environmental care requirements relevant to the work |
Appropriate personnel may include: | supervisors suppliers clients colleagues managers |
Blades may include: | wide band saw blades used for processing timber products narrow band saw blades used for cutting both ferrous and non-ferrous materials |
Sharpening is to include: | the amount of material removed from the tooth profile the ability to produce the required profile the 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 wheels and 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 language constructive feedback active listening questioning to clarify and confirm understanding use of positive, confident and cooperative language use of language and concepts appropriate to individual social and cultural differences control of tone of voice body 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 tooth damage to teeth pitch 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 sawn in wide bandsaw blades is achieved by swaging and shaping, or tipping tooth points in 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 at must 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 profiles rates are generally measured in teeth per minute |
Pre start-up checks | are conducted to ensure: machine has been set-up correctly systems 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 sawn changes 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 process re-using band saw blades that cannot be sharpened or are damaged in the process |
Records and reports may include: | the blade type size inspection grading and labelling outcomes storage locations quality outcomes hazards incidents equipment malfunctions and may be: manual using a computer-based system or other appropriate organisational communication system |
