Machinists
AI touches this job. It does not define it.
AI meaningfully touches parts of this work, yet the majority of its activities remain outside observed AI usage. That's balanced exposure: real efficiency gains are available without wholesale overlap.
Where this occupation sits among all 785 measured. Bands are quintiles of the real distribution. Applicability measures task overlap with observed AI usage. It is not a probability of job loss.
What this job involves
Set up and operate a variety of machine tools to produce precision parts and instruments out of metal. Includes precision instrument makers who fabricate, modify, or repair mechanical instruments. May also fabricate and modify parts to make or repair machine tools or maintain industrial machines, applying knowledge of mechanics, mathematics, metal properties, layout, and machining procedures.
Where AI overlaps this work, activity by activity
The occupation's most important work activities (O*NET weights, normalized to this set), each with its measured AI performance across 200,000 real conversations: how often AI is used for it, how well it completes it, and how much of the activity it covers.
| Work activity | Share of role | AI performance |
|---|---|---|
| Measure physical characteristics of materials, products, or equipment. | 17.8% | Moderate 0.42 |
| Operate industrial processing or production equipment. | 11.4% | Not observed 0.00 |
| Operate cutting or grinding equipment. | 10.3% | Not observed 0.00 |
| Monitor equipment operation. | 9.2% | Not observed 0.00 |
| Communicate with others about operational plans or activities. | 8.4% | High overlap 0.61 |
| Position workpieces or materials on equipment. | 8.1% | Not observed 0.00 |
| Test performance of equipment or systems. | 7.2% | Moderate 0.55 |
| Advise others on business or operational matters. | 6.2% | High overlap 0.70 |
| Maintain tools or equipment. | 6.1% | Not observed 0.00 |
| Assemble equipment or components. | 5.5% | Not observed 0.00 |
| Read documents or materials to inform work processes. | 5.0% | Moderate 0.55 |
| Program computer systems or production equipment. | 4.9% | High overlap 0.68 |
"Not observed" is a measurement, not missing data: that activity does not meaningfully appear in the usage sample. AI performance = completion × scope × coverage (user-goal view), 0–1.
What drives this score: the biggest AI-overlapped activity in this role is measure physical characteristics of materials, products, or equipment; the most important activity AI is not observed doing is operate industrial processing or production equipment. The plan below is built around exactly that split.
Balanced exposure: take the gains, deepen the moat.
Next 30 days
- Harvest the easy wins. Parts of this role, led by Measure physical characteristics of materials, products, or equipment, are already AI-assistable. Claim those hours back this month.
- Map your own mix. Your split may differ from the occupation average. Run the six-question personalization above and read your range, not the headline.
Next 90 days
- Invest saved time in the human core. The majority of this occupation's activities show no observed AI usage. Deepen exactly those, starting with Operate industrial processing or production equipment.
- Stay current, lightly. A monthly hour trying new tools on your real tasks beats panic-learning later.
The longer game
- Own a niche. Moderate exposure means AI will not define this occupation, but specialists who pair domain depth with tool fluency will out-earn generalists in it.
- Watch the boundary activities. If the 'Emerging' rows in your table above turn 'High' in a future data update, revisit the plan. No countdown clocks, just recheck.
