What kind of figure this source publishes
The BLS category is a relative rank, not an absolute level, and it is not a first-hand measurement: it groups an occupation's percentile ranks across several published studies into four bands. It is not an employment or wage forecast, not a probability of adoption, and it does not separate automation from augmentation.

Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

1.00/ 3· Robot exposure index
Scale, basis and source
Each physical task is graded 0–3 by the setting in which robots that have been deployed, sold or demonstrated could do it (0 none · 1 purpose-built robot settings such as a fenced machine cell or a bottling line · 2 structured facilities such as a hospital pharmacy or a container port · 3 unstructured settings such as a private home or a construction site), and the grades are averaged by share of working time
Physical tasks among this occupation's O*NET 29.3 tasks
Anthropic estimated the grades and time shares with Claude Opus 5 using web search, as of 2026.
The robot exposure index is a different measure from the AI exposure figures on this site and cannot be added to or compared with them. It does not measure actual adoption or cost, and 0 also covers occupations with no physical tasks.

ESCO occupational vocabulary
Each entry below is matched to this occupation in the published ESCO-O*NET Crosswalk (version 1, 2022). The match types are that crosswalk's; the wording is AI Changing Work's.
- deburring machine operatorESCO 8122.5This occupation is broader
Deburring machine operators set up and tend mechanical deburring machines designed to strip metal workpieces of their rough edges, or burrs, by hammering over their surfaces in order to smoothen them or to roll over their edges in case of uneven slits or sheers in order to flatten them into the surface.
- drill press operatorESCO 7223.6This occupation is broader
Drill press operators set up and operate drill presses designed to cut excess material from or enlarge a hole in a fabricated workpiece using a hardened, rotary, multipointed cutting tool that inserts the drill into the workpiece axially.
- fitter and turnerESCO 7223.7This occupation is broader
Fitters and turners use machine tools to create and modify metal parts according to set specifications in order to fit components for machinery. They ensure the finished components are ready for assembly.
- gear machinistESCO 7223.8This occupation is broader
Gear machinists make precision parts for gears and other driving elements. They use a variety of machine tools.
- metal nibbling operatorESCO 7223.11This occupation is broader
Metal nibbling operators cut detailed patterns from metal surfaces by using manual or powered metal nibblers, such as a handheld nibbling drill or a nibbling machine.
- punch press operatorESCO 7223.4.7This occupation is broader
Punch press operators set up and tend punch presses designed to cut workpieces into their desired shape by propelling a hydraulic ram to punch holes into them with a single die set that pushes through the top dead centre, through the surface, and to the bottom dead centre of the workpiece.
- screw machine operatorESCO 7223.19This occupation is broader
Screw machine operators set up and tend mechanical screw machines designed to manufacture (threaded) screws out of processed metal workpieces, specifically small- to medium-sized ones that have been turned by a lathe and turn machine.
- straightening machine operatorESCO 7223.22This occupation is broader
Straightening machine operators set up and tend straightening machines designed to form metal workpieces into their desired shape using pressing practices. They adjust the angle and the height of the straightening rolls and select the settings for the pressing force required to straighten the workpiece, taking into account the end product's yield strenght and size, without excess work hardening.
- swaging machine operatorESCO 7223.23This occupation is broader
Swaging machine operators set up and tend rotary swaging machines, designed to alter round ferrous and non-ferrous metal workpieces into their desired shape by first hammering them into a smaller diameter through the compressive force of two or more dies and then tagging them using a rotary swager, a process through which no excess material is lost.
- tool and die makerESCO 7222.5Overlapping, not the same
Tool and die makers operate a variety of equipment and machinery designed to create metal tools and dies, which are both needed in several areas of manufacturing, and produce these tools in all steps of the production process. They design the tools and dies, then cut and shape them to size and finish them by manually operated machine tools, power tools, hand tools, or programming and tending CNC tool and die making machines.
