FR5 inspection nest. Five nice contact faces in CAD; real brackets rock. How do I untangle the locating scheme?
Which of these nest contacts is supposed to locate the bracket?

Which surfaces are intended to set the bracket position, and which merely support it? Mark those on the drawing first. A clamp should hold a located part, not force several conflicting contacts to agree.
12分Drawing doesn't distinguish them. That's the problem.
3分Then ask the designer to explain each contact against the part drawing. Compare the bench samples with that scheme before changing the clamp. Their variation may show which contact is interfering with seating.
11分Has the clamp supplier actually seen a rocking sample, or have they only been told it needs holding down harder? I'm no fixture designer, but buying a bigger clamp seems a surprisingly expensive way to postpone that question.
10分A sample and the marked drawing would make a useful joint discussion. First establish how the part should sit; then decide how it should be retained.
14分Designer is reviewing the contacts with our samples. Bigger clamp removed from the purchase list for now.
