Will AI replace Milling and Planing Machine Setters, Operators, and Tenders, Metal and Plastic?

What this score means

Milling and Planing Machine Setters, Operators, and Tenders, Metal and Plastic 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 13 out of 100 it sits close to the Manufacturing average of 14. Across the 3 sources behind this baseline, individual estimates run from 7 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 Milling and Planing Machine Setters, Operators, and Tenders, Metal and Plastic, most central first, showing 12 of 15.

• 01Remove workpieces from machines, and check to ensure that they conform to specifications, using measuring instruments such as microscopes, gauges, calipers, and micrometers.
• 02Verify alignment of workpieces on machines, using measuring instruments such as rules, gauges, or calipers.
• 03Move controls to set cutting specifications, to position cutting tools and workpieces in relation to each other, and to start machines.
• 04Observe milling or planing machine operation, and adjust controls to ensure conformance with specified tolerances.
• 05Select and install cutting tools and other accessories according to specifications, using hand tools or power tools.
• 06Position and secure workpieces on machines, using holding devices, measuring instruments, hand tools, and hoists.
• 07Replace worn tools, using hand tools, and sharpen dull tools, using bench grinders.
• 08Study blueprints, layouts, sketches, or work orders to assess workpiece specifications and to determine tooling instructions, tools and materials needed, and sequences of operations.
• 09Compute dimensions, tolerances, and angles of workpieces or machines according to specifications and knowledge of metal properties and shop mathematics.
• 10Move cutters or material manually or by turning handwheels, or engage automatic feeding mechanisms to mill workpieces to specifications.
• 11Mount attachments and tools, such as pantographs, engravers, or routers, to perform other operations, such as drilling or boring.
• 12Select cutting speeds, feed rates, and depths of cuts, applying knowledge of metal properties and shop mathematics.
