Definition

Chatter is one of the most important limitations in machining processes causing poor surface finish, decreased tool life, and damage to the machine tool. Additional operations are required to clean the marks left on the surface; however this may not be possible in cases of severe chatter. In short, chatter vibrations result in reduced productivity, increased cost, and inconsistent product quality.

Chatter is a self-excited vibration type resulting from the dynamic interaction between the cutting tool and the work material (Tobias 1965; Koenigsberger and Tlusty 1967). For forced vibrations arising in mechanical systems, the excitation is independent of the response, i.e., the vibrations do not affect the forces. In self-excited chatter vibrations, on the other hand, the chip thickness becomes modulated due to the vibration marks left on the surface in a previous pass and the present vibrations causing...
