We run CNC Lathes here in a high production environment. We don't usually run into chatter problems unless we are dealing in long parts using a small diameter stock or deep bores that have a boring bar out past its recommended effective length ratio. This part mix is minimal for us. I think the dynamics plays a bigger role when you have a stationary part and rotating tooling (such as milling) vs stationary tooling and a rotating part (like a lathe).
