A variety of methods. Optical comparator, bore gauge, profilometer, visual inspection, etc. Now mind you this nozzle could fit in a 3" cube, and we have dimensions, profile features and such with less than 0.001" tolerance.

Seems like user errors to me. Faro said they have 13 micron precision and that's 0.00052" accuracy. Now if it is off by 1 unit that'll be a swing between 0.00052" and 0.00104", not enough to measure.
Was wondering if they can use optical method to measure, why would they use a contact type measurement like Faro.
