Operators use a computer numerical control (CNC) milling machine
to cut and shape metal into components used in manufacturing.
A CNC milling machine operator controls the automated tool
digitally with numerical codes or instructions called G-Code. These
instructions drive the tool, rather than physical levers and
wheels. The tool selectively removes material, usually metal from
the raw material, to shape it into the required component, such as
engine parts.
CNC milling has improved flexibility in manufacturing processes
as it is quicker and more adaptable than traditional techniques.
Operators of CNC milling machines need to understand the
manufacturing process and be able to program the CNC milling
machine accurately.
