Almost all you'll ever need to know about gauge blocks [1]. It's also a fairly decent introduction to the uncertainties of measurements, and other factors of taking measurements of objects. Of course it also includes a section on wringing. (and other sources on papers about the wringing phenomenon) [1] https://www.nist.gov/sites/default/files/documents/calibrations/mono180.pdf https://www.nist.gov/sites/default/files/documents/calibrati... Further more, if you're really interested in how modern precision engineering/industrial manufacturing came to be; I highly highly recommend you look into Foundations of Mechanical Accuracy by Moore. (it's a $150 book, pdf easily found by googling.) (I'm a flatness/metrology nerd. I recently lapped three cast iron plates together just because I wanted to create as flat a surface as I could. Just because. )
