Test a new aluminium extrusion die

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

1

Interpret die drawing and die specifications relevant to die trial

1.1

Identify work health and safety (WHS), regulatory requirements and risk management requirements associated with extruder operation and die handling

1.2

Identify layout and pre-forming of die apertures

1.2

Identify bearing and pocket design/specification

1.3

Identify measurements and tolerances for bearings, die components and die support system

1.4

Identify bolster and spacer specification for die

1.5

Identify press specifications

1.6

Identify speed estimate for die

1.7

Identify ports and bridges for hollow dies

2

Liaise with die designer

2.1

Clarify die drawing and die specifications with die designer where design information is not clear

2.2

Determine if die requires finishing off and clarify final design measurements, tolerances and speed specifications

2.3

Obtain any special instructions from die designer for conduct of test extrusions

3

Finish off die, if required

3.1

Finish lands and bearings to specified tolerances

3.2

Finish ports, bridges and mandrels of hollow dies, if required

3.3

Undertake any final polishing

3.4

Confirm all measurements are to design specification after finishing off

4

Analyse trial extrusions

4.1

Check extruder and surrounds for compliance with operation safety requirements

4.2

Operate or supervise operation of extrusion press to produce trial extrusions

4.3

Check hot extrusions for shape distortion

4.4

Check thickness of extrusions are to specification

4.5

Check surface finish of extrusions

4.6

Identify whether faults apply from the start to the end of the runout of the extrusions

4.7

Conduct additional trial extrusions to confirm extrusion faults occur consistently

4.8

Record extruder settings for each trial extrusion

5

Identify appropriate remedy for out of specification results

5.1

Examine faulty extrusions and determine if fault relates to die design, incorrect process or temperature settings, or faulty die support system

5.2

Determine fault is die related and able to be eliminated through correction of die

5.3

Determine if fault can be corrected through adjustments to die supports

5.4

Determine if fault can be eliminated through adjusted process control or billet heating

5.5

Recommend either return of die for re-design or manufacture of a new die where faults are unable to be corrected

6

Re-test die after correction

6.1

Conduct trial extrusions after correction of die, die support adjustment or process or temperature adjustment

6.2

Return die to die manufacturer if faulty extrusions persist

6.3

Record adjustments to die on die design drawings ensuring correct feedback codes are used

6.4

Record adjustments made to die support system, process and temperature settings
