Application
This unit of competency defines the skills and knowledge required to perform production machining using engineering machinery.
Production machining refers to use of workshop machines for volume production of parts or components made of metal or other machinable materials where the machine operator has responsibility for the setting up of the machine, including tooling, grinding wheels, and other accessories within defined parameters. It does not include one-off jobbing on workshop machines or complex calculations. Tolerances and tool paths will normally have been set in advance.
Where trade machining applications are undertaken unit MEM07005 Perform general machining should be selected.
Where set up and operation of electro-discharge machines (EDM) is required unit MEM07014 Perform electro-discharge machining (EDM) operations should also be selected.
Where machining is undertaken without the need for any set up, including mounting of tools, setting of speeds, feeds and other operational parameters then unit MEM07024 Operate and monitor machine and process and unit MEM07025 Perform advanced machine and process operation, should also be selected as appropriate.
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.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
