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

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 for maintenance

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 in line with manufacturer's recommendations.

1.3 Plan maintenance process in line with work order.

2. Assess saw condition

2.1 Follow organisational safety procedures thoughout all maintenance and repair processes.

2.2 Remove wide band and gang saws from machinery.

2.3 Handle saws to avoid damaging teeth.

2.4 Clean foreign material on blade surfaces for inspection.

2.5 Inspect saw to assess condition of teeth, tips and saw blade.

2.6 Check and mark teeth or tips requiring repair or replacement.

2.7 Declare saw unserviceable where hazardous defects are found.

2.8 Segregate and dispose of unserviceable saws in line with organisational procedures and environmental protection practices.

3. Level, tension and back-gauge saw blade

3.1 Assess and match ridges or lumps across and along saw on both sides of blade.

3.2 Use gauges and straight edges in both directions to test blade accuracy.

3.3 Remove ridges or lumps progressively through levelling and use stretcher or levelling rolls to flatten.

3.4 Localise stresses using controlled levelling or rolling patterns to avoid spring-back and re-occurrence of defects.

3.5 Check saw blade against required curvature using a gauge to identify tensioning requirements.

3.6 Obtain tension curvature across and along saw blade.

3.7 Check alignment of saw back against tolerances using a gauge; roll non-conforming areas to obtain required tolerance.

4. Repair teeth and blade cracks

4.1 Place saw blade in welding jig for heat application and welding activities.

4.2 Check amount of damaged tooth to be removed or crack to be repaired and mark weld line.

4.3 Remove metal to proposed line, prepare edge for welding and clean burn marks.

4.4 Apply heat and pressure to prepare worn, broken or ground surface for metal build up or replacement.

4.5 Build up or replace teeth or cracked area using material and prcoesses that ensure specified metal penetration and density.

4.6 Use weld run-off tabs to limit stress and hollows at edges of saw blade.

4.7 Grind or file teeth or cracks to required shape, tolerance and pitch.

4.8 Dispose of saws with irreparable teeth, tips or blades in line with organisational procedures environmental protection practices.

4.9 Identify routine processing and equipment faults and resolve or report to appropriate personnel.
