Lathe and Turning Machine Tool Setters, Operators, and Tenders, Metal and Plastic

16,710 US workers · median $50,620/yr · Production

EXPOSED

The tending tier — loading bar stock, cycling parts, gauging with calipers and micrometers, logging counts — is exactly what bar feeders, robotic loaders, in-process probing, and lights-out CNC cells already absorb, and CAM software plus AI now drafts G-code and tooling strategies that operators once wrote by hand. What holds is the setup and troubleshooting tier: fixturing an odd part, dialing tool offsets, reading chatter and chip color, chasing a tolerance drift on a live job, and swapping inserts on a machine that doesn't care what the program says. The modal worker here straddles both tiers, which is why the number sits near the border rather than in the safe zone.

10-year outlook: Employment keeps shrinking as automated cells and multitasking machines consolidate work, but shops will still pay well for setters who can fixture, program, and troubleshoot a job nobody has run before.

US employment, 2019–2025-40.5%
28,07016,710 workers

This fall is concentrated in 2020 and has not recovered since.

Median pay $40,100 → $50,620 +1.0% in real terms (nominal +26.2%, less ~25% US inflation over the period)

The job count is not the verdict

This line is counted by the Bureau of Labor Statistics — the one figure on this page that isn't a judgement of ours. Headcount moves on demand, offshoring, demographics and the business cycle, and automation is one term among several, often not the loudest.

So a falling line is not evidence that AI did it, and a rising one is not evidence that it won't. Both happen in this register: some occupations resist automation and shrink anyway, others are highly automatable and keep growing. The marked year is 2020.

BLS projection, 2024–2034

-13.6% 18,900 → 16,400 on the projections basis

Exposed, and shrinking

Both signals point the same way: the tasks are largely automatable and the BLS projects -13.6% by 2034. This is the case where the score and the forecast agree, and it is the one worth taking seriously.

Different clocks. The score is what current AI could do to this work today. The projection is how many of these jobs will exist in 2034. Everything between the two — how fast employers actually adopt, whether demand grows in the meantime — is why they can point opposite ways without either being wrong.

~1,500 openings a year on average, including replacing people who leave.

Score — 35/100 resistance

Holding it up: embodiment (14/20). Weakest point: liability shield (1/20).

Five dimensions, 0–20 each, summed. Higher means more protected. The arithmetic is shown so you can check it: 10 + 14 + 1 + 3 + 7 = 35. · Scored 2026-08-11, and re-examined when evidence accumulates rather than on a schedule.

Task resistance 10/20

Mixed — a routine tier and a judgment tier Loading a bar feeder and pressing cycle-start is already lights-out work, but nobody has automated indicating a four-jaw chuck to a half-thou, hearing a boring bar start to chatter and dropping feed on the fly, or re-shimming a soft jaw because the casting came in oversize — the split between those two halves of your shift is what puts this at 10 and not 4 or 15.

Embodiment 14/20

Hands-on in uncontrolled environments You are inside the machine envelope with a dial indicator, changing inserts and toolholders, blowing out chips, dealing with coolant mist and hot swarf, and hauling bar stock — 14 rather than 18 because it's your own guarded machine on a shop floor, not a rooftop or a trench where conditions change on you.

Liability shield 1/20

No licence, no signature requirement No licence, no stamp, no certificate anyone checks: a shop can hire you Monday on a trial run, and when a shaft goes out of tolerance the liability sits with the QC sign-off and the company's contract, not your name — the 1 rather than 0 is only the OSHA lockout/tagout duty you personally carry at the machine.

Trust premium 3/20

Anonymous artifact production The turned part ships in a bin and the customer never learns who ran it; the 3 reflects that a programmer or shift lead comes to you specifically when a job won't hold size, which is internal reputation, not a client relationship that follows you.

Judgment & accountability 7/20

Meaningful discretion You decide when to bump an offset, when an insert is done, and when to stop the run and call it scrap — real calls with real money in them, but bounded by the print, the tolerance block, and the setup sheet, which is why this is 7 and not the 14+ of someone deciding what the tolerance should be.

This occupation has already been through one. Headcount fell 43.6% between 2017 and 2025 — 29,620 to 16,710 — while the median wage held roughly flat in real terms (+ 0.6% after inflation). A job being commoditised usually loses pay along with headcount. One that shrinks by half while pay holds is leaving a specialist core behind, and the score above was assigned from the occupation title without sight of that history — so it may be describing the job this used to be rather than the people still doing it. Why this is a known limit.

Where this experience transfers — occupations you could move toward

Computed from U.S. Dept. of Labor O*NET skill and knowledge profiles: high overlap with what you already do, a materially higher resistance score, no large jump in required training, and no licence you would have to start a new pipeline to get. Targets that pay meaningfully less, that are themselves COOKED, or whose own headcount is falling are excluded — a move into a shrinking trade is not an escape.

What would move this back up — beyond any one person

The moves above are yours to make. This is the other half: what would have to change in the world for the occupation itself to score higher. None of it is in any one person's gift, but it is where the floor actually comes from. Scores here are not a one-way ratchet. Only two of the five dimensions — task resistance and embodiment — track what machines can do. The other three track law, what buyers will pay for, and who is answerable, and those move in both directions, often in response to the same pressure AI creates. If every lever below landed, this occupation would score around 50/100, still EXPOSED.

5 specific changes that would raise this score
  • already happening task resistance +4

    Task-mix shift is genuine here: as bar feeders, robotic loaders and in-process probing absorb loading/gauging/counting, the surviving job is setup, fixturing odd geometries, tool offset dial-in and live troubleshooting (chatter, chip color, tolerance drift). A shop that moves to lights-out spindles and retains one setter per several machines has raised the per-worker judgment content even as headcount falls.

  • plausible task resistance +3

    Growth of low-volume/high-mix work — aerospace spares, medical implant one-offs, defense reshoring under DoD Industrial Base programs — where setup time dominates cycle time and no fixture or program is reused, keeps the non-automatable fraction high.

  • plausible liability shield +3

    AS9100/NADCAP and FDA 21 CFR 820 audit practice already requires a named individual to sign first-article inspection and setup approval sheets. If prime contractors extend the requirement to explicitly bar AI-generated or unverified programs from being run without a named setter's signed process verification — the way Boeing and Rolls-Royce supplier quality clauses have tightened on process control — the signature becomes a job-defining requirement rather than paperwork.

  • plausible judgment accountability +3

    Where the setter owns the call to scrap, rework, or accept a drifting lot on a $40k forged blank, and that call is logged against their name in the MES for CAPA traceability, the accountability is real. Formalizing scrap-disposition authority at the setter level (rather than escalating to a quality engineer) raises this.

  • plausible embodiment +2

    Shift toward large-diameter, long-bar, or exotic-alloy turning (titanium, Inconel) where workholding is manual, deflection and thermal growth are felt not measured, and robot cells are uneconomic at the batch size.

The limit. Trust premium has no realistic route — buyers of turned parts specify tolerance, material cert and PPAP, not human authorship, and no customer pays a premium for hand-cranked chips. Even with every lever pulled, this stays a shrinking-headcount occupation: the levers raise the value of the workers who remain, not the number of them.

These are conditions, not forecasts — what would have to happen, not what will. Specific rules, cases and bills are named so you can go and check whether they exist and where they stand; verify before relying on any of them. Nothing here is legal or financial advice.

Where this work is, and what it pays there

BLS metro figures for 61 areas. The verdict above does not change by city — the rubric judges what the work involves, not where it happens — but pay and headcount do, and the national median hides a very wide range.

Who is actually doing this — nobody, on the record

We have no reported case of a named organisation automating this occupation. Not one deployment, not one announcement.

That is worth saying out loud next to a score of 35. The verdict above is about what the work exposes — what current AI could do to these tasks. It is not a claim that anyone has done it. For this occupation those two things have come apart completely: the capability argument is on this page, and the evidence column is empty.

Read that as a gap in the reporting we can see, not proof of absence — the dispatch runs on English-language feeds and misses plenty. If you know of a case, tell us, or add a field report from inside the job.

Quick take — do you do this job?

Field reports — what people say has changed

No field reports yet. A written account takes a paragraph rather than a tap, goes to an editor before it appears, and is the one thing on this page the rubric cannot produce on its own.
