Design of a tuned mass disc damper with variable natural frequency for chatter suppression

Abstract

This paper presents a tuned mass disc damper (TMDD) for chatter suppression during metal cutting. The design utilizes the vibration of one cantilever beam. By the variation of the beam length, the natural frequency of the TMDD could be easily and accurately tuned to match the critical frequency of the primary structure. The damping effect of the TMDD is generated from the collision and the friction between the discs and the host structure, therefor it is essentially independent of the environment temperature and very durable.
