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

AI can do 10% of the work Milling and Planing Machine Setters, Operators, and Tenders, Metal and Plastic do at least twice as fast. Real use has not caught up: none of their tasks show up in real AI use yet, but AI could speed up 2 of them. Robots can technically handle 10 physical tasks. 3 still need a person.

AI is already doing this0 · 0% of time

People already use AI for these tasks in real work, based on Anthropic's analysis of how Claude is used.

  • Real AI use has not reached any of this job's tasks yet.

AI could do this next2 · 10% of time

AI can speed these up by at least half, but real use has not caught up yet. These are next in line.

  • Select and install cutting tools and other accessories according to specifications, using hand tools or power tools.8% of time
  • Record production output.2% of time

Robots can technically do this10 · 79% of time

Physical tasks that today's robots can perform in at least some settings. Robots are cost competitive for very few tasks so far, so this change moves slower.

  • Observe milling or planing machine operation, and adjust controls to ensure conformance with specified tolerances.Robots: structured workplaces20% of time
  • Position and secure workpieces on machines, using holding devices, measuring instruments, hand tools, and hoists.Robots: purpose built settings14% of time
  • Remove workpieces from machines, and check to ensure that they conform to specifications, using measuring instruments such as microscopes, gauges, calipers, and micrometers.Robots: purpose built settings12% of time

Still needs a person3 · 11% of time

No real AI use, no proven AI speedup and no robot that can do it yet. This is the part of the job to build on.

  • Study blueprints, layouts, sketches, or work orders to assess workpiece specifications and to determine tooling instructions, tools and materials needed, and sequences of operations.6% of time
  • Compute dimensions, tolerances, and angles of workpieces or machines according to specifications and knowledge of metal properties and shop mathematics.2% of time
  • Select cutting speeds, feed rates, and depths of cuts, applying knowledge of metal properties and shop mathematics.2% of time

What this means

Little of this work suits AI. The bigger change here is robots: today's robots can technically do 86% of the working time, though they are rarely cheap enough to replace people yet.

What to do next

  • Get ahead on the 2 tasks AI could do next. These move as tools improve, so learning them early pays off.
  • Keep an eye on the 10 physical tasks robots can technically do. Cost keeps most robots out of work today, so this shift is slower.
  • Build on the 3 tasks that stay human. This is where your judgment, skill and relationships matter most.
