They depend on lapping, which can be done “manually” by the robot arm. I forgot to list “abrasive powder” in my list of vitamin ingredients. Fixed now.
The fancier optical techniques provide precision on the order of a wavelength, which is far in excess of our needs. All we need is eyeball-class optical techniques like looking along an edge to make sure it’s straghtish, or pressing a part against a surface plate and seeing if light passes under it.
Don’t those methods tend to rely on lapping and optics? You don’t seem to have any equipment for those.

I really like this video on the subject of how humanity first developed precision machines: https://youtu.be/gNRnrn5DE58?si=NMk1BAsU6_XMuLbL
