I've had tidy nests locate on every convenient surface except the drawing datum; which contacts are supposed to locate, and which merely support or clamp?
Our bracket nest has several contacts and no consistent seat

Don't increase force to hide a seating disagreement before anyone has identified it.
14 pointsPavel's distinction matters, but also establish whether the samples conform to the relevant part requirements. A contact conflict and a damaged bracket can look similar from above; the bench record should identify the actual samples and the condition in which they were checked.
7 pointsCan the designer mark the intended freedoms and constraints on the existing drawing before you buy or modify anything?
-2 pointsAnd identify who owns that marked revision. Stores cannot maintain a locating scheme that exists only in this conversation.
10 pointsThe nest drawing names all of them contact pads but does not separate their functions. I will ask the designer for that map and quality for the sample condition records.
11 pointsAre you seeing the brackets rock before the clamp closes, or only discovering a different position afterwards?
6 pointsBefore closure: some rock diagonally on the bench nest. I have not increased the clamp setting. The sample IDs are recorded, but conformity has not yet been checked.
22 pointsCan you preserve the as-found contact evidence for those identified samples before anybody dresses a pad?
17 pointsThat should be possible through the tooling team's approved bench inspection, without buying the stronger clamp or treating a hand-held sample as a robot-loading trial.
7 pointsHas the designer explained why those diagonal contacts are there? Rocking shows inconsistent seating, but not yet which contact is wrong.
5 pointsAgreed, Lin. My datum example was a reason to inspect the scheme, not a diagnosis of Ella's nest; the pads could also be made or assembled wrong.
5 pointsQuality checked the identified brackets against the relevant drawing requirements and found no discrepancy in that sample group. The designer's map shows two contacts both locating the same direction against different bracket features.
4 pointsThat makes a competing-contact explanation plausible, but ask for the actual feature variation and contact locations in the review. Two contacts sharing a direction are not automatically incompatible; their intended geometry and the permitted part variation determine whether they fight each other.
14 pointsExactly. Don't swap an unsupported clamp diagnosis for an unsupported pad diagnosis.
19 pointsThe dimensional overlay shows the auxiliary contact can engage before the intended locating face across our sample variation. Designer proposes relieving that contact, with its support function reconsidered rather than simply deleting it.
10 pointsDoes the proposal retain a defined way to resist the intended loads after that contact changes?
-2 pointsAnd show the clamp acting into the intended support, not pulling the bracket into the old contradictory position. The force discussion can come after that.
23 pointsHas the revised nest actually been checked, or is the overlay the latest evidence?
6 pointsOverlay only. The stronger-clamp order is cancelled, and the designer is completing the revised support and restraint assessment before a bench comparison. No revised nest approved yet.
