Under continuous machining conditions, two types of vibration occur as a result of movement between a work-piece and tool: external vibration (result of interference force transmitted through the foundation into the machine); self-excited vibration, (the machine system oscillates, basically, at one or more natural frequencies, when no external forces are acting).
They also provide a unique analysis of dynamical problems, such as nonlinear rotordynamics, self-excited vibration, nonstationary vibration, and flow-induced oscillations.
