BLS
  • All figures are for the United States as a whole. Pay varies a lot by state and city.
  • Wages are for everyone working in the occupation in May 2025, at every career stage. They are not starting salaries or figures for new graduates.
  • Growth and openings are BLS projections for 2025–35. They are estimates, not promises. Openings include jobs that open up when people retire or change occupation, not just new jobs.

What the work involves

Operate computer-controlled tools, machines, or robots to machine or process parts, tools, or other work pieces made of metal, plastic, wood, stone, or other materials. May also set up and maintain equipment.

Main tasks

  • Measure dimensions of finished workpieces to ensure conformance to specifications, using precision measuring instruments, templates, and fixtures.
  • Set up and operate computer-controlled machines or robots to perform one or more machine functions on metal or plastic workpieces.
  • Mount, install, align, and secure tools, attachments, fixtures, and workpieces on machines, using hand tools and precision measuring instruments.
  • Review program specifications or blueprints to determine and set machine operations and sequencing, finished workpiece dimensions, or numerical control sequences.
  • Stop machines to remove finished workpieces or to change tooling, setup, or workpiece placement, according to required machining sequences.
  • Listen to machines during operation to detect sounds such as those made by dull cutting tools or excessive vibration, and adjust machines to compensate for problems.
  • Implement changes to machine programs, and enter new specifications, using computers.
  • Calculate machine speed and feed ratios and the size and position of cuts.
