our bracket nest seats differently before anyone tightens the clamp

What is each contact supposed to locate? If two features demand incompatible positions, more clamp force won't explain which one should win.
7分Before condemning the nest, check the sample faces and obvious contamination. I've seen a chip make a reasonable tool look badly designed. Not saying that's your case.
16分And ask the loader how the bracket gets into it. A guide may look redundant once seated while still doing useful work during loading.
23分The drawing calls every pad support, with no distinction between guides and locating contacts; I have asked the designer to mark their intended roles.
-6分That's not enough definition to approve a stronger clamp. Does the inspection datum scheme appear on their drawing at all?
9分Bruno, the role drawing matters, but I'd still preserve the condition of the actual bench samples. We could otherwise blame the design for one damaged face.
13分Inspection is checking the samples; I am keeping the seating observations separate from its dimensional results so one does not substitute for the other.
17分Agreed. I was objecting to approving the clamp, not claiming we'd proved conflicting contacts.
12分Can you repeat the manual seating with one identified bracket before comparing different brackets? That separates inconsistent placement of the same part from variation between parts.
7分For Clara Carter's comparison, keep the loading direction recorded too; don't make the operator improvise a new approach on every repeat.
7分The same bracket repeats consistently, but another sits on a different combination of pads; inspection found both within their checked drawing requirements, and the designer is reviewing those contacts.
12分That points the next review towards how permitted part variation meets the nest. It doesn't mean every within-tolerance bracket has been demonstrated. Keep the sample identities with the contact observations.
6分Has the designer proposed a contact change, or are they still asking for a harder clamp?
5分They are separating the guide function from final location in a revised proposal; thanks Yasmin, I nearly asked them to delete a guide the loader actually needs.
6分Glad it stayed in the discussion. I'd have the loader review the revised approach before the bench comparison, then let the comparison decide whether seating is actually improved.
