本文回顾了金属切削和磨削过程中颤振的基本建模。还介绍了如何避免工业中的颤振。回顾了单点加工操作的正交颤振稳定性定律和波瓣的基本原理，其中该过程是一维且时不变的。介绍了正交稳定性在车削和镗削加工中的应用，同时讨论了导致频域求解困难的过程非线性。讨论了钻井振动的建模。介绍了铣削的动态建模和颤振稳定性。将各种稳定性模型与经过实验验证的时域仿真模型结果进行比较。横向和切入磨削操作的动态时域模型通过实验结果给出。总结了离线和实时颤振抑制技术及其在工业中的实际应用和局限性。本文提出了一系列研究主题，这些主题还有待研究以在工业中有效使用颤振预测和抑制技术。
This paper reviews fundamental modeling of chatter vibrations in metal cutting and grinding processes. The avoidance of chatter vibrations in industry is also presented. The fundamentals of orthogonal chatter stability law and lobes are reviewed for single point machining operations where the process is one dimensional and time invariant. The application of orthogonal stability to turning and boring operations is presented while discussing the process nonlinearities that make the solution difficult in frequency domain. Modeling of drilling vibrations is discussed. The dynamic modeling and chatter stability of milling is presented. Various stability models are compared against experimentally validated time domain simulation model results. The dynamic time domain model of transverse and plunge grinding operations is presented with experimental results. Off-line and real-time chatter suppression techniques are summarized along with their practical applications and limitations in industry. The paper presents a series of research topics, which have yet to be studied for effective use of chatter prediction and suppression techniques in industry.
