CNC machinists use computer numerically controlled (CNC) machine
tools to cut, drill, shape and finish products and components used in
the engineering and manufacturing sectors. Many people take courses and apprenticeships in this area to get
into this type of role, though some learn on the job. They work
primarily with metals but also deal with wood, composite materials
The tools they operate include lathes, cutters, milling machines, grinders, borers and machines that combine several of these functions. Products include parts for the automotive, power, marine and aerospace industries, and manufacturing and machine tools for the engineering sector.
Machinists program the CNC machine tool with data taken from technical drawings. Some machines display the section on a screen so that the process can be worked out visually.Typical duties include:
The CNC machines are designed and set to produce large quantities of components to exactly the same specifications. Should small quantities of a product be required, hand-operated machine tools may be used.
CNC machinists work a 39-hour week, Monday to Friday. Overtime
may be available. Shiftwork may include weekends, evenings and
Machinists work in factories and workshops standing at the machine as it operates. Although heavier materials can be positioned with hoists, some manual lifting of smaller products will be required.
Protective overalls, boots, goggles and earguards are normally worn.
