This unit describes the performance outcomes required to carry out machining operations on a range of automotive components to specific tolerances. It involves preparing for the task, selecting the correct machining operation, setting up and machining components to specifications, and completing workplace processes and documentation. It also involves restoring surface finishes and tolerances, and aligning components.
It applies to those working in the automotive service and repair industry. The machining operations apply to those using lathes, and milling or surface grinding machines.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the machining operations that they have carried out, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions detailing work requirements, including work specifications
AS4182 Automotive repairs – Code of practice for reconditioning reciprocating spark ignition engines
AS4427 Automotive repairs – Code of practice for reconditioning reciprocating compression ignition engines
machinery as specified in the performance evidence
precision measuring equipment, including inside and outside metric and imperial micrometers
ferrous and non-ferrous material relevant to carrying out machining operations.
