A production fixture doesn't fail dramatically — it drifts. A locating pin wears 0.05mm. A toggle clamp spring loses tension. A bushing opens up another half-thou. First the part passes QC with a wider margin, then it starts rejecting, then nobody can find the moment the fixture stopped being capable. This checklist catches the drift at each of its five wear points before it costs a shift's output. OXMAINT AI is the AI-powered CMMS and maintenance management software that holds every fixture, every inspection record, every worn-pin replacement — so a drifting fixture becomes a planned refurbish, not a scrap-run surprise.
Clamps, locating pins, bushings, datum surfaces, alignment — five wear points decide whether a fixture is still capable or is quietly scrapping parts. The OXMAINT AI software holds the daily / weekly / monthly / annual cadence per fixture, raises a work order the moment a check fails, and keeps the full repair and refurb history against the fixture ID.

Fixture Anatomy — The Five Wear Points
Every production fixture has the same five families of wear point. The names change between a weld jig, a machining fixture and an assembly nest, but the physics is the same — and so is the check cadence. OXMAINT AI holds each wear point against the fixture with its specific tolerance and replacement part — schedule a walkthrough of the fixture wear register in OXMAINT AI.

The Four-Cadence Check Matrix
Not every check belongs on the daily walk, and not every check waits for the annual refurb. Each wear point has a check at each frequency. OXMAINT AI auto-schedules these as recurring work orders per fixture.

The Full Fixture Inspection Checklist
Walk this list on the agreed cadence. Every item is a real checkbox — filed in OXMAINT AI from a phone next to the fixture, timestamped to the fixture ID. Any unchecked box blocks the fixture from "approved for use" status.

BLOCK B · Locating Pins & Datum References
BLOCK C · Bushings, Bores & Guides
BLOCK D · Alignment, Geometry & Fixture ID
A Drifting Fixture Scraps Parts for Weeks Before Anyone Looks at It.
Quality catches the symptom — a rising reject trend. Fixture maintenance catches the cause. The OXMAINT AI software ties every reject back to the fixture that made the part, so a 0.03mm pin wear becomes a planned replacement, not an argument between quality and production.
Not every finding stops a fixture. Three severity bands decide what happens after the check — and OXMAINT AI routes each to the right action automatically.
MONITOR
Early wear within spec — log the reading, keep the fixture in service, watch the trend to next check.
PLAN REPAIR
Approaching tolerance limit — raise a planned work order against the fixture for the next shop window.
STOP & TAG
Out of tolerance or safety issue — red-tag the fixture, remove from service, repair before next use.
Every fixture held with ID tag, wear points, tolerances and spare-part list — one asset record per tool.
Four-Cadence PM Scheduler
Daily, weekly, monthly and annual checks auto-raised as work orders — nothing drifts off the calendar.
Mobile Checklist Capture
Native checkboxes filed from a phone at the fixture; readings and photos timestamped to the asset.
Red-Tag & Stop-Use Flow
A critical finding tags the fixture out of service in the register — it cannot be scheduled for production until the repair closes.
Reject-to-Fixture Tie-Back
Parts that failed QC are tied to the fixture that made them — a rising reject trend surfaces the suspect tool first.
Refurb & Replacement History
Every pin replaced, bushing re-sleeved and clamp rebuilt retained — the fixture's full service life in one place.
Frequently Asked Questions
Which single wear point drives most fixture problems?
Locating pins — they take the datum load every cycle and wear is almost invisible until a part starts rejecting. Monthly gauge checks catch it before it crosses tolerance. Start free and set up pin-wear tracking in OXMAINT AI.
How do we tie fixture wear to actual part rejects?
OXMAINT AI stores the fixture ID on each production work order. When QC logs rejects against a part, the trend rolls up to the fixture — a rising reject rate surfaces the suspect tool before quality calls a stand-down.
Do we need a separate CMMS just for fixtures?
No. Fixtures sit alongside machines in the asset register with their own schedules and spare parts. Keeping them in the same system is the point — so the production work order and the fixture PM share one planner.
How fast can we have fixture maintenance running?
Most plants have the register, cadence and mobile checklist configured in OXMAINT AI within two to three weeks once the fixture list and tolerances are loaded.
Catch the Drift Before It Scraps the Shift.
Put every production fixture on the OXMAINT AI maintenance management software — wear points registered, four-cadence PMs auto-scheduled, mobile checklist filed on the floor, reject trend tied back to the tool. The fixture that drifted on Tuesday becomes a planned refurb on Friday.
