Yeah, that's why tenths (~2.5 microns) are used when thousandths aren't precise enough. I'm definitely not claiming it's a good, I'm just describing the system

I'm definitely not claiming it's a good, I'm just describing the system I have seen used in the handful of machine shops I've spent time in.
- jbay808 5y agoI think YZF just mis-parsed your sentence, and thought you meant a thou is for very high precision work, while you meant that a tenth is for very high precision work. (That said, I'd add -- measuring to one part in 10^6, for anything except time, is challenging but still very doable; machining to one part in 10^6, for anything beyond very simple shapes, does require pretty exotic methods or very great care, and to verify it you have to measure to one part in 10^7).
