Our customer is designing a CMM part fixture (for injeciton molded plastic parts) with air suction cups to restrain the parts... cool idea in theory, until you realize they are still using the exact same upper clamps with springs that are producing a 0.003" constraint bias on a critical dimension.
The whole point of redesigning the fixture was to eliminate the constraint bias. *facepalm*
