Work activities

As a CNC machinist, you would:

  • work from blueprints, sketches, or computer-aided design (CAD) and computer-aided manufacturing (CAM) files
  • plan the most efficient order of machine operations for the job
  • program the machine tool with data
  • align, secure, and adjust cutting tools and workpieces
  • set and monitor the feed and speed of machines
  • turn, mill, shape, and grind machine parts to specifications
  • check completed parts against required quality and technical standards.

Machinists can learn to operate a variety of CNC machine tools that can produce a large number of components to the same standard and specification, such as lathes, grinding machines, milling machines, drills and presses.

Working hours and conditions

Working Hours

You would normally work a standard number of hours per week, which may include shiftwork.

Conditions

You would spend most of your time in a factory or workshop, operating and monitoring the machines.

You would do a lot of lifting, either by hand, or using mechanical hoists. You would stand for long periods of time, and perform repetitious movements. For most jobs you would wear protective clothing such as overalls, boots, goggles and earplugs to dampen the noise produced by machinery.

Job outlook

  • 1 2 3 4 5

Overall employment of CNC machinists is projected to grow faster than the average for all occupations.

Machinists will be required to set up, monitor, and maintain these automated systems. As manufacturers invest in new equipment, modify production techniques, and implement product design changes more rapidly, they will continue to rely heavily on experienced machinists.

The projected growth may be offset somewhat by the closure of major manufacturing industries in Australia, such as automotive vehicle manufacturing.
