Control method of chatter vibration based on inverse analysis of end milling chatter mark

Nihon Kikai Gakkai ronbunshu, 2017
It is well known that a regular chatter mark appears on the machined surface when chatter vibration occurs. There must be an essential information relationship between the chatter mark and the vibration stability.
