Application
This unit of competency defines the skills and knowledge required to perform electro-discharge machining (EDM) operations and applies to a range of EDM operations and engineering materials.
This unit has been primarily developed for Engineering Tradesperson - Mechanical apprenticeship training and the recognition of trade-level skills in performing EDM operations.
Where the selection and use of power tools/hand held operations is required unit MEM18002 Use power tools/hand held operations should also be selected.
Where electrodes are required to be manufactured see appropriate machining units.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Band: A
