Chatter is a self-excitation phenomenon occuring in machine tools, in which the
cutting process tends to decrease the machine structural damping
ending with an unstable behavior.
Solution based on ADDs have been implemented on a big milling
machine (Soraluce SV6000). They will be used to assess its performances in reducing the chatter
phenomenon appearance (see video - MPEG, 3 Mo).
One can clearly see that the ADDs prevent the apparition of the chatter by
increasing the initial structural damping of the machine.
