What an assessment for MEM07021 must cover

31 assessable components: 4 elements (15 performance criteria), 8 performance evidence and 8 knowledge evidence requirements. 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 Determine job requirements

1.1Follow standard operating procedures (SOPs)
1.2Comply with work health and safety (WHS) requirements at all times
1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.4Identify job requirements from specifications, drawings, job sheets or work instructions

2 Set up work on lathe

2.1Determine sequence of operations, including job set-up, for maximum efficiency to meet job specifications
2.2Set up work on the lathe to required level of accuracy using precision instruments, including dial test indicators
2.3Balance work piece when using face plates to ensure accuracy in machining, as required
2.4Set up work piece to ensure that work piece is free of distortion following completion of machining

3 Select and prepare tooling

3.1Select tooling, accessories and consumables appropriate to task, specifications and material
3.2Determine cutting tool modifications required to perform complex turning operations, where appropriate
3.3Prepare tooling and accessories and modify, as required
3.4Apply International Standard Organisation (ISO) standards for cutting tools or other appropriate standards to suit cutting parameters

4 Perform complex turning

4.1Calculate speeds and feeds using appropriate mathematical techniques and reference material
4.2Undertake complex turning to specifications and workplace procedures
4.3Measure work piece and verify in accordance with specifications using precision measuring equipment

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
identifying and interpreting specifications, charts, lists, drawings and other applicable reference documents in performing complex lathe operations
setting and supporting work to avoid distortion on release of clamping devices
selecting and setting up cutting tooling or inserts as appropriate to turning operation
calculating cutting parameters, speeds and feeds to meet job requirements
modifying tooling and accessories, as required
performing complex turning operations according to specifications
checking machined components for conformance to specifications

Knowledge evidence

Questions about assessing MEM07021

What does an assessment tool for MEM07021 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM07021 needs to address all 31 unit components: 4 elements with 15 performance criteria, 8 performance evidence requirements, 8 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 MEM07021?

Auditori pulls the current release of MEM07021 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 MEM07021 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM07021 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 MEM07021, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
