本文提出了一种新的主动振动控制策略，以减轻机床进给驱动的高频再生颤振。而不是模态阻尼，提出的方法旨在控制再生过程动力学，以形成稳定性波瓣图（SLD），并获得更高的材料去除率。控制器被设计成一个反馈滤波器，其参数被优化以补偿再生。提出的策略应用于主动控制正交（骤降）车削动力学，其中>2.5 [kHz]颤振被快速刀具伺服（FTS）驱动系统抑制。稳定性叶在局部成形，达到高达4倍的材料去除率。(c) 2021 CIRP。Elsevier Ltd.出版。版权所有。
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. (c) 2021 CIRP. Published by Elsevier Ltd. All rights reserved.
