Boring operations are usually limited by chatter vibrations related to the flexibility of boring bars. The location of a passive tuned mass damper close to the tool tip is a widely proposed solution, which has demonstrated robust results. However, the main drawback of this solution is that the dampers must be tuned for a certain frequency, being a customized solution for each boring bar. Active devices can overcome this limitation due to their adaptability to changing actuation frequencies. This work describes the development of a reluctance-based modular active inertial damper for its application in the suppression of chatter vibrations in slender boring bars. The solution provides the possibility to perform chatter-free boring operations at different bar overhangs due to the important stability improvement obtained in a broad frequency range.
