The daily work — mounting wheels and abrasives, dialing in feeds and speeds, loading parts, checking dimensions with micrometers and gauges, deburring and finishing by feel — is hands-on and resists language AI almost entirely. The real threat here is not chatbots but the machinery itself: CNC grinders with in-process gauging, automatic wheel dressing, and robot part loading have been eating the tending tier for decades, and employment has trended down accordingly. Setters who can hold tight tolerances on unfamiliar geometries and troubleshoot chatter, burn, and taper keep their value; someone who loads a part and presses cycle-start does not.
Mixed — a routine tier and a judgment tier. Dressing a wheel to the right form, sneaking up on a 0.0002-inch bore size, and reading burn marks or chatter patterns on a part cannot be done from a keyboard, but repeat-run tending on a CNC grinder with in-process gauging is already automated in high-volume shops — that split between irreplaceable setup and replaceable cycle-start puts it at 13 rather than 17.
Hands-on in uncontrolled environments. You are standing at the machine mounting wheels, balancing them, flooding coolant, loading fixtures, and hand-deburring with files and stones — but it is a shop floor with fixed equipment and known part flow, not a rooftop or a trench, so it lands at 13 rather than the high teens.
No licence, no signature requirement. Nothing about this job requires a licence: no state credential to run a surface grinder, and when a part goes out of tolerance the quality inspector's signoff and the shop's certification (AS9100, ISO) absorb it, not your name.
Anonymous artifact production. Your ground parts leave in a tote with a first-article report attached; the customer buys the tolerance and the surface finish and never learns who set the machine, though a lead who consistently makes tough jobs run gets asked for by the scheduler.
Executes defined procedures on defined inputs. Feeds, speeds, wheel grit, and dress amounts come off a process sheet or the setup sheet from engineering, and print tolerances define pass/fail — the discretion is real when you compensate for a taper or change dress frequency mid-run, but you are not deciding whether the part design is acceptable.
