What an assessment for MEM05087 must cover

34 assessable components: 3 elements (15 performance criteria), 6 performance evidence and 13 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 Write basic NC/CNC machine program

  • 2.1Identify machine safety features
  • 2.2Check alignment of material to machine cutting head/s and datum points
  • 2.3Select appropriate program elements for machine controller
  • 2.4Interpret engineering drawings to define basic machine function and cutting path geometry
  • 2.5Accurately calculate co-ordinates for cutting path
  • 2.6Write program in standard code format in accordance with procedures

3 Write NC/CNC operation sheet and trial program

  • 3.1Produce operation sheets to specification in accordance with SOPs
  • 3.2Operate machine in manual mode to test and prove program
  • 3.3Edit program to adjust operation based on testing outcome
  • 3.4Check components for compliance to specification
  • 3.5Save final program and complete operation sheets and records in accordance with SOPs

Performance evidence

  • follow work instructions, standard operating procedures (SOPs) and safe work practices
  • identify and interpret job specifications, engineering drawings, and other applicable work instructions for information relevant to writing basic numerical control (NC) and/or computer numerical control (CNC) programs for thermal cutting machines
  • interpret basic NC/CNC thermal cutting machines controller elements which do not require programming using canned cycles and sub-routines
  • write a basic program in standard code format by interpreting drawings to define basic machine function and cutting path geometry and calculating co-ordinates for cutting path and producing operation sheets to specifications on at least two occasions
  • trial and edit basic programs by operating machine in manual mode to test and prove program and adjusting operation as required on at least two occasions
  • check components for compliance against specifications.

Knowledge evidence

  • safe work practices and procedures and use of personal protective equipment (PPE)
  • elements of a basic NC/CNC program
  • function of elements in controlling the operation of an NC/CNC machine
  • types of NC/CNC thermal cutting and welding machines and their applications
  • thermal cutting operations controlled by a program
  • cutting paths to be followed when cutting a part or product and the reasons for selecting cutting paths and sequence of operations
  • zero point of the NC/CNC machine
  • standard codes, applications and procedures used in the writing of NC/CNC programs
  • procedures and information to be included for completing NC/CNC operation sheets
  • procedures for manual operation of the NC/CNC machine and reasons for testing and proving the NC/CNC program
  • procedures for editing the NC/CNC program via the machine controller
  • effects of editing on the operation of the NC/CNC machine and the part or product to be cut
  • measuring equipment and techniques used to check for conformance to specification.

Questions about assessing MEM05087

What does an assessment tool for MEM05087 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM05087 needs to address all 34 unit components: 3 elements with 15 performance criteria, 6 performance evidence requirements, 13 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 MEM05087?

Auditori pulls the current release of MEM05087 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 MEM05087 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM05087 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 MEM05087, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
