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