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.
Task-level exposure

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.

0.75/ 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.

ILO occupational description
AI Changing Work links the ISCO-08 unit groups below to this occupation by applying the U.S. Bureau of Labor Statistics crosswalks (2018 SOC to 2010 SOC, 2010 SOC to ISCO-08) as published, without case-by-case selection; each link may be whole or partial.
- ISCO-08 7222Toolmakers and Related Workers
The definition, tasks and examples below are the ILO's description of that unit group, not of this occupation.
Toolmakers and related workers make and repair custom-made and specialised tools, sports guns, locks, dies, patterns, machinery components and other metal articles using hand and machine tools to work metal to fine tolerances.
Tasks
- (a) reading and interpreting engineering drawings and specifications of tools, dies, prototypes or models;
- (b) preparing templates and sketches, and determining work processes;
- (c) visualizing and computing dimensions, sizes, shapes and tolerances of assemblies, based on specifications;
- (d) positioning, securing and measuring metal stock or castings to lay out for machining;
- (e) setting up, operating and maintaining conventional and computer numerically controlled machine tools to cut, turn, mill, plane, drill, bore, grind or otherwise shape work pieces to prescribed dimensions and finish;
- (f) fitting and assembling parts to make and repair jigs, fixtures and gauges;
- (g) repairing and modifying sports guns and other small arms;
- (h) making, fitting, assembling, repairing and installing lock parts and locks;
- (i) making and repairing metal patterns for preparation of foundry moulds;
- (j) laying out lines and reference points on metal stock to guide other workers who cut, turn, mill, grind or otherwise shape metal;
- (k) verifying dimensions, alignments and clearances of finished parts for conformity with specifications, using precision measuring instruments and testing completed items for proper operation.

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.
- casting mould makerESCO 7222.1Overlapping, not the same
Casting mould makers create metal, wooden or plastic models of the finished product to be cast. The patterns are then used to create moulds, eventually leading to the casting of the product of the same shape as the pattern.
- mouldmakerESCO 7211.1.3Overlapping, not the same
Mouldmakers manually create moulds for the production of metal products. They mix sand and hardening materials to obtain a specialised mixture. They then use a pattern and one or more cores to produce the right shape impression in this material. The shaped material is then left to set, later to be used as a mould in the production of ferrous and non-ferrous metal castings.
