It is a phenomenon in which abnormal vibrations are generated during cutting and grinding processes, resulting in the formation of characteristic chatter marks on the machined surface.
Chatter marks are formed on the machined surface. The mechanism of chattering is caused by the periodic fluctuation of the removal area (regeneration effect) caused by machining the vibrating surface generated during the machining of the previous surface, or by the Coupling of multi-directional vibrations modes (Mode-coupling).
