For reference, in working with parts that interface directly with optical components about the tightest I’m ever comfortable specifying at production volumes is 0.05mm and that is for very specific dimensions and not entire parts yet he is demanding 5 times lower tolerances here.

blargerer@kbin.social 1 year agoYou aren't going to hit that tolerance consistently on an assembly line no matter how much you pay. Can be done by a skilled machinist, but there are too many dynamical variables in an assembly line environment, like the previously mentioned thermal expansion.

I guess they could do like Nissan did with the GTR’s engine: climate controlled assembly bay, temperature check on the parts etc…
But I mean, they did it only for the engine which is relatively small

It’s not even about that. You absolutely don’t need those tolerances for a cup holder. An assembly line will fuck it up regardless. You use tolerances like that when needed - in jet engines or turbines. Insisting on those numbers on a car is plain stupid - it isn’t better (other than the ego boosting “my car has high tolerances where nobody cares”) than just doing it like every other manufacturer does it. It’s a waste of money plain and simple.
