Influence of chatter of VMC arising during end milling operation and cutting conditions on quality of machined surface

Machine tool chatter is a dynamic instability of the cutting process. Chatter results in poor part surface finish, damaged cutting tool, and an irritating and unacceptable noise. Extensive research has been undertaken to study the mechanisms of chatter formation. Efforts have been also made to preve...
