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.enhttps://creativecommons.org/licenses/by/4.0/BoringChatterDamped boring barDampingModellingSelf-excited vibrationTuned mass damperManufacturingConference Paper10.15480/882.809910.1016/j.procir.2023.03.03410.15480/882.8099Conference Paper
