Will AI replace Computer Numerically Controlled Tool Operators?

What this score means

Computer Numerically Controlled Tool Operators is among the least exposed roles in Manufacturing. Most of what the job involves still sits outside what current AI can do, even as the tools around it keep changing. At 15 out of 100 it sits close to the Manufacturing average of 14. Across the 3 sources behind this baseline, individual estimates run from 5 to 20, so the score is a weighted consensus rather than any single figure.

The number is a consensus estimate for the typical version of the role, built from published academic and industry research scored occupation by occupation. It is not a prediction about any individual. How scoring works

What this job actually involves

Exposure follows the work itself rather than the job title, so it is worth seeing what the role is made of. These are the tasks O*NET records for Computer Numerically Controlled Tool Operators, most central first, showing 12 of 27.

• 01Write simple programs for computer-controlled machine tools.
• 02Lift workpieces to machines manually or with hoists or cranes.
• 03Measure dimensions of finished workpieces to ensure conformance to specifications, using precision measuring instruments, templates, and fixtures.
• 04Set up and operate computer-controlled machines or robots to perform one or more machine functions on metal or plastic workpieces.
• 05Mount, install, align, and secure tools, attachments, fixtures, and workpieces on machines, using hand tools and precision measuring instruments.
• 06Review program specifications or blueprints to determine and set machine operations and sequencing, finished workpiece dimensions, or numerical control sequences.
• 07Stop machines to remove finished workpieces or to change tooling, setup, or workpiece placement, according to required machining sequences.
• 08Listen 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.
• 09Implement changes to machine programs, and enter new specifications, using computers.
• 10Calculate machine speed and feed ratios and the size and position of cuts.
• 11Transfer commands from servers to computer numerical control (CNC) modules, using computer network links.
• 12Remove and replace dull cutting tools.
