I mostly agree with what what said above. I believe there is a hierarchy of importance. First, the device needs to be within tolerance of it’s designed use. You can’t have an implant that is too big or small from it’s designed size. Next, you need to have the correct tolerances in the parts. If the pieces won’t fit together properly, it’s not a working product. Lastly, the tolerances allow for machining differences. If you required exact changes, you could make a few in spec, but soon after due to natural changes/differences in the machinery you would fall out of spec very quickly.
