What an assessment for AURTTM012 must cover

37 assessable components: 4 elements (21 performance criteria), 1 performance evidence and 9 knowledge evidence requirements, plus 6 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare to grind camshaft

1.1Job requirements are determined from workplace instructions
1.2Camshaft is cleaned and inspected, lobe lift is measured, and condition is reported
1.3Camshaft grinding information is sourced, procedures and methods are analysed, and appropriate grinding machine and master are selected for camshaft
1.4Hazards associated with the work are identified and risks are managed
1.5Tools and measuring equipment are selected and checked for serviceability
1.6Camshaft grinding wheel is dressed to match job requirements
1.7Camshaft is positioned in grinder and clamped according to manufacturer specifications and workplace procedures, and centre run-out and bend are checked

2 Grind camshaft lobes

2.1Camshaft grinder movement is set to master according to manufacturer procedures, and position of camshaft to master is verified statically
2.2First set of camshaft lobes are ground according to manufacturer specifications, workplace procedures, and safety and environmental requirements
2.3Master is re-phased to suit next cylinder’s lobes, and lobes are ground according to manufacturer specifications, workplace procedures, and safety and environmental requirements
2.4Remaining camshaft lobes are ground according to manufacturer specifications, workplace procedures, and safety and environmental requirements
2.5Camshaft is measured to ensure compliance with specifications and that base circles are true

3 Finish camshaft grinding

3.1Camshaft is prepared for phosphating according to manufacturer specifications, workplace procedures, and safety and environmental requirements
3.2Camshaft is phosphated according to manufacturer specifications, workplace procedures, and safety and environmental requirements
3.3Journals are linished according to manufacturer specifications, workplace procedures, and safety and environmental requirements
3.4Camshaft profile is identified on camshaft according to workplace procedures
3.5Bright surfaces are treated with rust prevention solution and camshaft is prepared for further process or storage according to workplace procedures

4 Complete work processes

4.1Final inspection is made to ensure finished work complies with workplace requirements and camshaft is presented ready for use or storage
4.2Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
4.3Tools and equipment are checked and stored according to workplace procedures
4.4Workplace documentation is processed according to workplace procedures

Performance evidence

grind one camshaft of an in-line engine with at least four cylinders.

Knowledge evidence

work health and safety (WHS) and occupational health and safety (OHS) requirements, including: - procedures for selecting and using personal protective equipment (PPE) for: - handling camshafts - using chemical cleaning agents - operational risk assessment and treatments associated with: - electrical safety of grinding machinery - grinding machinery movement and operation
environmental requirements, including procedures for trapping, storing and disposing of cleaning and lubricating fluids released during the grinding process
types, characteristics and limitations of camshaft grinding machines, including use of cam doctors
cleaning and inspection procedures, including: - determining camshaft lobe profile and timing requirements - checking camshaft centre run-out - checking camshaft for bend
procedures for preparing camshaft grinding wheel, including: - dressing and truing to restore original cutting geometry and correct flatness and roundness
procedures for camshaft lobe grinding, including: - roughing and finishing
procedures for finalising camshaft grinding, including: - linishing - phosphating - identifying camshaft profile on camshafts
requirements of Australian standards relevant to engine reconditioning, including: - AS 4182 Automotive repairs – Code of practice for reconditioning reciprocating spark ignition engines - AS 4427 Automotive repairs – Code of practice for reconditioning reciprocating compression ignition engines
post-grinding procedures, including protection of machined surfaces

Foundation skills

Learning skills: locate camshaft machine settings in workshop and manufacturer literature.
Reading skills: identify and interpret camshaft specifications from workshop literature interpret machinery safe operating procedures from operating manuals.
Writing skills: legibly and accurately fill out workplace documentation when recording: - parts and materials used - measurements and camshaft specifications.
Numeracy skills: interpret numerical information in manufacturer specifications, workshop literature, and machinery dials, gauges and computer readouts use basic mathematical operations, including addition and subtraction, to: - convert metric dimensions to imperial, and imperial dimensions to metric - calculate tolerances and clearances.
Planning and Organising skills: select best tooling option for the work and sequence procedure to reduce time and material wastage.
Technology skills: use precision metric and imperial measuring equipment.

Questions about assessing AURTTM012

What does an assessment tool for AURTTM012 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURTTM012 needs to address all 37 unit components: 4 elements with 21 performance criteria, 1 performance evidence requirements, 9 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for AURTTM012?

Auditori pulls the current release of AURTTM012 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for AURTTM012 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURTTM012 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of AURTTM012, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
