Maintain wide band saw blades

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria

ELEMENT

PERFORMANCE CRITERIA

1. Prepare for maintenance

1.1. Applicable Occupational Health and Safety (OHS), environmental, legislative and organisational requirements relevant to maintaining wide band saw blades are identified and followed

1.2. Work order is reviewed and checked with appropriate personnel

1.3. Wide band and gang saws to be maintained are removed from the designated machinery

1.4. Equipment is selected appropriate to work requirements and checked for operational effectiveness in line with manufacturer's recommendations

1.5. Maintenance process is planned in line with site procedures and environmental requirements

1.6. Communication with others is established and maintained in line with OHS requirements

2. Assess saw condition

2.1. Saws are handled safely without damage to teeth

2.2. Foreign material built up on blade surfaces is cleaned for inspection

2.3. Saw is inspected to assess condition of teeth and saw blade

2.4. Teeth and tips requiring repair or replacement are checked and marked

2.5. Saw is declared unserviceable where hazardous defects are found and disposed of in line with site procedures, manufacturer's recommendations and environmental requirements

3. Level, tension and back-gauge saw blade

3.1. Ridges or lumps across and along saw are assessed and matched on both sides of the blade

3.2. Gauges and straight edges are used in both directions and monitored for accuracy

3.3. Ridges or lumps are progressively removed through levelling and the use of stretcher rolls or levelling rolls to achieve flatness

3.4. Levelling or rolling patterns are controlled to localise stresses to avoid spring-back and re-occurrence of defects

3.5. Saw blade is checked against required curvature using a gauge to identify tensioning requirements

3.6. Tension curvature is obtained across and along saw blade in line with required standard

3.7. Alignment of saw back is checked against saw tolerances using a gauge and areas not conforming are rolled to obtain required tolerance

4. Repair teeth and blade cracks

4.1. Saw blade is placed in welding jig for applying heat and undertaking welding activities

4.2. Weld line is marked to check amount of damaged tooth to be removed or crack to be repaired and selected to minimise stresses

4.3. Metal is removed to the proposed line, the metal edge is prepared for the welding process and cleaned free of burn marks

4.4. Worn, broken or ground surface is prepared for metal build up or replacement by applying heat and pressure

4.5. Teeth or cracked area is built up or replaced using compatible welding material and welding procedures that ensure specified metal penetration and density

4.6. Weld run-off tabs are used to limit stress and hollows at edges of the saw blade

4.7. Teeth or cracks are ground or filed to required shape, tolerance and pitch

4.8. Saws where teeth, tips or blade cracks are damaged during the repair process and cannot be repaired are disposed of in line with site procedures, manufacturer's recommendations and environmental requirements

4.9. Repair process and equipment faults are investigated, recorded and reported in line with site requirements
