摘要:
镗削颤振是金属切削过程中产生的不稳定现象，成为影响和制约零件加工表面质量及加工效率提高的主要因素。深入开展切削颤振形成的机理研究，是实现切削颤振抑制的理论核心之一，具有重要的理论价值。本文总结了颤振形成的机理和主动控制的基本思路，回顾了近年关于镗削颤振及保证稳定性的主要研究成果，并根据近年来预测控制研究的发展趋势，指出高效主动控制逐渐成为这一领域研究的热点。
Boring chatter instability in the metal cutting process turn out to be the main factor affecting which constrains the surface quality and processing efficiency. Studying cutting chatter mechanism and its variation in flutter is one of the theoretical core of cutting chatter suppression with an important theoretical value. In this paper, the fundamental philosophy in the study on cutting chatter mechanism and active control is summarized. The main theoretical works on boring chatter active control with guaranteed stability and performance are reviewed. From the trend of recent study, we point out that the high efficient active control will be the focus of the afterward study in this area.
