ABSTRACT:
Disclosed is a method for suppressing the self-excited chatter vibrations in a machine tool of the type having a "non-rotating" tool or of the type having a "rotating" tool. According to this invention a chatter suppressing contact is provided to itself the tool of the non-rotating type machine tool or to the rotating spindle to which the tool is fixed in the rotating type machine tool in such a way that the chatter suppressing contact slidably reciprocates on the tool or the rotating spindle thus changing the contact point with time. As a result the natural frequency of the tool is changed while it is employed in machining, and the self-excited chatter vibration are suppressed. The chatter suppressor contact which is used in a non-rotating type machine tool is in the form of an auxiliary tool holder, whereas the chatter suppressor contact which is used in a rotating type machine tool is in the form of a ball or roller bearing.
