Why the Same 0.01 mm Part Measures Differently in Two Buildings
A 20 µm tolerance band is not a property of metal. Temperature, probe contact, clamping and datum choice each take a slice of it, and the slices add up faster than the drawing assumes.

A 20 µm tolerance band is not a property of metal. Temperature, probe contact, clamping and datum choice each take a slice of it, and the slices add up faster than the drawing assumes.
Bar capacity, guide bushing clearance and unsupported length decide the tolerance on a Swiss-type part - not the machine's spec sheet.
An optical housing has to satisfy a mechanical envelope and an optical reference at once. Where those two requirements collide, and how to specify around it.
Ra is an average, not a specification. How finish bands map to real processes, where tight callouts are functional, and how to write a callout that gets quoted correctly.

Imagine capturing the exact shape of a real-world object — every curve, edge, and tiny dent — and turning it into a digital 3D model in just a few minutes.
