Chatter arises due to the unstable vibration or undulation of the tool or workpiece, which poses a challenge. This chapter introduces a novel technique using metal particles to develop passive particle damping for effectively suppressing chatter in the boring process. This approach utilizes the collision energy of the particles to attenuate the chatter. The damper’s performance was evaluated by boring a mild steel workpiece with and without a damper. Based on the measured displacement and excited frequency, it is evident that the developed particle damping approach provides better damping by reducing the chatter. This leads to improved machining stability and surface quality. The findings presented in this study hold promising implications for enhancing the performance and efficiency of boring processes across a wide range of industrial applications. This research contributes to the growing body of knowledge in advanced manufacturing techniques and underscores the potential of copper–zinc-based particle damping as a reliable solution for chatter suppression in machining operations.
