“That’s why designers, engineers and architects put tolerances on drawings/models.”
Those are manufacturing tolerances.
There are no tolerances in the above, only probabilities of a given outcome.
True about the probabilities... physical tolerances are defined so the product will assemble and function properly.
One of the most interesting manufacturing challenges I had was to grind a hemispherical shell of ceramic to the tightest tolerance I could. That included concentric position of the inner and outer hemisphere. Our CMM was a Zeiss with about a 3 micron accuracy and it showed everything spot on. The customer bought 4 of the grinders and had us build 2 frames so they could convert them to CMM’s. Fun project. the hemispheres were about 20” or 500mm across.
