I'm sorting the proposal notes for an FR10 welding cell and our gusseted bracket is lovely in the fixture, then the released hole spacing fails, then someone corrects it and the final pass gets copied over the first failure, so I can't even tell which bit of this job we're budgeting for anymore
Which drawing revision governs the released hole spacing? And what supports the bracket during that measurement? Start there. A photograph of it clamped square is not a measurement of the finished bracket.
Anna, drawing P, measured released on the inspection support named on that sheet; Mina, yes there's an asset label and it matches, I've checked that rather than trusting the nickname this time
Then you've got a usable before-and-after comparison if you keep the part identities together. For the fixture model I'd show where each piece sits before the clamps close, otherwise you can accidentally draw the corrected shape as the starting shape
Why are we blaming the weld already? Could the gusset be wrong before anyone strikes an arc? I would want that answered before paying for a different welding sequence.
The fabricator has a fit-up photo from the failed bracket and the gusset isn't against the rear stop before clamping, I'd missed that because the later photo is all closed up (thanks Sam, wrong photo was doing all the talking)
Yes, both. I'd label the photo as the observed fit-up and put the designer's intended contacts beside it, so nobody models that gap as something we're meant to preserve
We found a locator from an earlier assembly on a similar fixture. A comparison of the fitted stop with its drawing was cheaper than our first proposed experiment.
Tooling found an old stop still fitted behind the gusset, its number belongs to the earlier bracket and the current assembly calls for a different face position, so the fabricator wasn't imagining the awkward fit
Have they checked first release after correcting that assembly? Keep any later correction separate. That will tell your estimator whether the old allowance still describes this job.
Three identified brackets through the corrected fixture now, all passed the P check at first release with no correction, and the estimator has replaced the old assumed correction time with those actual observations plus a note that it's only three parts; I can finally explain the price change without pretending the first failures never happened
