This paper presents a new active vibration control strategy to mitigate high frequency regenerative chatter vibrations using machine tool feed drives. Rather than modal damping, proposed approach aims to control regenerative process dynamics to shape the Stability Lobe diagram (SLD) and attain higher material removal rates. The controller is designed as a feedback filter whose parameters are optimized to compensate regeneration. The proposed strategy is applied to actively control orthogonal (plunge) turning dynamics where >2.5 [kHz] chatter vibrations are suppressed by a fast tool servo (FTS) drive system. Stability lobes are shaped locally to reach up to 4x higher material removal rates.

本文提出了一种新的主​​动振动控制策略，以使用机床进给驱动器减轻高频再生颤振。所提出的方法不是模态阻尼，而是旨在控制再生过程动力学以塑造稳定叶图 (SLD) 并获得更高的材料去除率。控制器设计为反馈滤波器，其参数经过优化以补偿再生。所提出的策略应用于主动控制正交（切入）车削动力学，其中>2.5 [kHz] 的颤振被快速刀具伺服 (FTS) 驱动系统抑制。稳定叶局部成形，材料去除率最高可达 4 倍。
