I wonder if a engine knock sensor would work? Switching to constantly varying rpm is effective I've heard - do you have an experience with it?

I think one sensor near the spindle nose. They are the only ones I know of building it in to a production machine, and the reviews are good. Detecting the emergence of chatter is wildly obvious when you look at the frequencies. I've even checked out audio of chatter and it's really easy to pick out in the frequency plots. I think it'd be doable in software. Once it's detected there's a very simple algebraic expression from the current chattering spindle speed to get one that doesn't. My only concern is that you would also have to monitor load on the spindle in case dropping the spindle speed overloaded the spindle, requiring reducing feed until the spindle load dropped to a reasonable value.
