What this score means.
Most of this role's work is still hard for AI: physical presence, practised skill, judgement in context and direct care, the things that do not turn into text.
If you are in this role
Nothing here is under pressure today, but the frontier moves. Learn enough to direct AI at the paperwork around the job. People in hands-on roles who can do that become unusually useful inside their organisations.
A few tasks in this role are within reach of AI, mostly paperwork, scheduling and routine writing. The shape of the role stays the same, and some parts get faster.
If you are in this role
Pick the two or three most repetitive things in your week and try a model on them. Most people underestimate what Claude or ChatGPT already does with admin-shaped work. The time you get back is the gain.
Where the work usually starts.
This role's strict reading is low because its top tasks are judgement, not drafting. The three highest-stakes tasks below are still usually where the work starts. Switch to With tools to see what AI plus the right context can take on.
-
Verify dimensions, alignments, and clearances of finished parts for conformance to specifications, using measuring instruments such as calipers, gauge blocks, micrometers, or dial indicators.
-
Set up and operate conventional or computer numerically controlled machine tools such as lathes, milling machines, or grinders to cut, bore, grind, or otherwise shape parts to prescribed dimensions and finishes.
-
Visualize and compute dimensions, sizes, shapes, and tolerances of assemblies, based on specifications.
These are the most important tasks AI can already handle when paired with the right tools and context. The first wins usually come from building workflows around them. That is the difference between a model that could do the job and one that actually does it inside your business.

-
Visualize and compute dimensions, sizes, shapes, and tolerances of assemblies, based on specifications.
-
Study blueprints, sketches, models, or specifications to plan sequences of operations for fabricating tools, dies, or assemblies.
Every role has three or four places like these. Finding them takes an hour. Turning them into a workflow your team actually uses takes a few days.

Smooth and polish flat and contoured surfaces of parts or tools, using scrapers, abrasive stones, files, emery cloths, or power grinders.
Measure, mark, and scribe metal or plastic stock to lay out machining, using instruments such as protractors, micrometers, scribes, or rulers.
Conduct test runs with completed tools or dies to ensure that parts meet specifications, making adjustments as necessary.
Design jigs, fixtures, and templates for use as work aids in the fabrication of parts or products.
Cut, shape, and trim blanks or blocks to specified lengths or shapes, using power saws, power shears, rules, and hand tools.
Set up and operate drill presses to drill and tap holes in parts for assembly.
Set pyrometer controls of heat-treating furnaces and feed or place parts, tools, or assemblies into furnaces to harden.
