Vibration and Chatter in Machining Operation

MACHINE-TOOL CHATTER Chatter is a self-excited vibration which is induced and maintained by forces generated by the cutting process. It effects surface finish, tool life, production rate and also produce noise. Chatter resistance of a machine tool is usually characterized by a maximum stable (i.e., not causing chatter vibration) depth of cut b lim.
