Tuned mass dampers (TMD) are an established method to reduce self-excited chatter vibrations in turning. Regarding boring bars, the susceptibility to chatter increases with increasing length and, even more, with decreasing tool diameter. A novel TMD for boring bars with diameters down to 10mm is presented. The TMD-design, consisting of a mass and a spring-damper combination, is based on analytical and numerical modelling. By using a futed boring bar design, the available design space allows to place a damping mass of sufcient mass ratio at the tool tip. Cutting tests showed the reduction of vibrations.
