Precision is a word that's throw around a lot in manufacturing. Nowhere are the requirements and challenges for precision higher than in aerospace machining.

Despite their complex geometries and often ultra-thin tolerances, parts manufactured for the aerospace industry frequently have to stand up to high stress loads and vibration levels while surviving extreme environments. These factors - and the reality that some parts could wind up hundreds of millions of miles from earth, where there are no options for repair - make the margin for error nano-thin.
