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
- Registered Training Organisations
- Trying to find someone to train or assess you? This link lists all the RTOs that are currently registered to deliver MEM07042A, 'Undertake corrections and basic maintenance to aluminium extrusion dies and die support systems'.
- Google Links
- links to google searches, with filtering in place to maximise the usefulness of the returned results
- Books
- Reference books for 'Undertake corrections and basic maintenance to aluminium extrusion dies and die support systems' on fishpond.com.au. This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to ntisthis.com for every purchase, so go nuts :)
Elements and Performance Criteria
1 | Prepare for die correction | 1.1 | Identify work health and safety (WHS), regulatory requirements, and risk management procedures relevant to die access and handling, extruder operation and die correcting procedures |
1.2 | Identify extrusion specifications, extruder operating procedures and other information relevant to die correction task | ||
1.3 | Where required, consult with die designer on intended correction |
2 | Correct solid dies | 2.1 | Calculate intended change in extrusion flow or speed |
2.2 | Determine bearing choke angles or length of bearing shortening as appropriate for required correction | ||
2.3 | Speed up flow, where required, through appropriate shortening of bearing | ||
2.4 | Slow down flow, where required, through appropriate choking of bearing | ||
2.5 | Relieve clearances | ||
2.6 | Supervise or run trial extrusions to test corrections |
3 | Correct hollow dies | 3.1 | Assess if shortening or choking of mandrel bearings is required and select bearings to be corrected |
3.2 | Determine choke angles and length of shortening as appropriate for required corrections | ||
3.3 | Undercut mandrel to widen chambers, where required | ||
3.4 | Increase depth of chamber back into bridge, where required | ||
3.5 | Adjust mandrel stems, where required | ||
3.6 | Adjust weld bridges, as required | ||
3.7 | Speed up flow, where required, through appropriate shortening of bearing | ||
3.8 | Slow down flow, where required, through appropriate choking of bearing |
4 | Undertake basic maintenance of dies | 4.1 | Monitor case and assess when re-nitriding is required |
4.2 | Prepare die for re-nitriding | ||
4.3 | Clean and polish dies when required | ||
4.4 | Repair fine bearing damage | ||
4.5 | Maintain bearing angle and flatness during polishing and repairs | ||
4.6 | Monitor fittings and devices for lifting die and die support components and arrange replacement or repair as necessary |
5 | Adjust die support system and components | 5.1 | Ensure toolstack components are flat and square with die |
5.2 | Check for and replace any coined bolsters | ||
5.3 | Check die slide alignment is within tolerance and re-align if necessary | ||
5.4 | Report persistent die support related faults after adjustment and recommend redesign or stiffening as appropriate |
6 | Maintain die records | 6.1 | Record details of all die corrections, including trial extrusions |
6.2 | Recommend any simple die design changes that increase productivity and recovery |
