Chatter is a common vibration phenomenon in machine tools, as well as one of the main causes of machining quality decline.
Chatter is a dynamic instability phenomenon by which the forces that occur during machining processes “supply” energy to the system; the same energy can cause rapid and uncontrolled vibration.
Chatter is determined by parameters such as cutting depth and rotational speed. Work stability is usually ensured by a combination of these two parameters.
When it comes to machining process, it is essential to be able to “push” a machine tool to its maximum, enhancing the two parameters. But it is also necessary to have systems capable of reacting immediately when chatter is detected.
