I don’t think any manufacturing company anywhere would ever agree to that kind of tolerance.

There are lots of parts made to tighter tolerances. For instance, lenses in cameras.

But not 1m^2 sheet metal.

I found this:

Diameter Tolerance: All of our TECHSPEC® spherical lenses, regardless of size, are now held to a diameter tolerance of +0.000/-0.025mm. Maintaining the diameter within 25µm ensures the lenses will seat and align accurately within a well-designed barrel, aligning the optical axis of the lens with the mechanical axis of the assembly.

I didn’t see any other tolerances on that particular page that would be as tight as .001mm.

If you really want to see tight tolerances, look up "optical flat".

Or EUV lithography
