In Part 1, I asked a simple question: “What is accuracy?” Now lets take the next step. Imagine a customer tells you: “We need 100 nm positioning accuracy.” Sounds clear enough. But in practice, that is usually where the real engineering discussion starts. Where does that accuracy need to be achieved? Over what travel and under what load? At what speed, temperature and payload? Where is the position actually measured, and how does that measurement relate to the point where the process is taking place?
