In this paper, a frictional damper is proposed for suppression of chatter in slender endmill tool. This damper is made up of a core and a multi fingered hollow cylinder. The core is press fitted into the hollow cylinder, and they both are press fitted into an axial hole inside the tool. This combination produces a resisting frictional stress against bending vibration. An analytical model including accurate modeling of friction in sliding and pre-sliding regions is developed for this damper. Based on the simulation of the analytical model a parameter study is done to achieve optimum parameters of damper that increases the stability limit as much as possible. Finally, the optimal damped tool with damper inside is fabricated and experimentally tested in compare with traditional tool. The results show a considerable improvement in tool performance. An acceptable agreement between analytical and experimental results is obtained which show the effectiveness of damped tool in improvement of tool performance.
