"In order to avoid chatter vibrations, usually a process planning is performed before manufacturing. This involves some calculations based on the tool and the machine dynamics that yield the stability lobes diagram. On this purpose, two approaches are available: one based on the time domain, and another based on the frequency domain. A matter of current discussion is which one of them is better according to the desired target. All of the above is argued in this paper, explaining the stability lobes diagram calculations ..."
