摘　　要：金属切削系统通常带有鲜明的时滞特征。颤振是广泛存在于金属切削加工过程的一种高度复杂动力学现象,而颤振预测是实现稳定切削的前提。从切削系统颤振预测的理论、在线监测方法,以及各种影响因素等方面对金属切削动力学研究的进展进行评述,简要介绍了不同材料在机床结构动力学设计中的应用研究进展,指出了存在的问题及其今后的研究方向。Metal cutting processes typically had distinct characteristics of delayed system.Chatter phenomenon was a highly complex phenomenon which widely occured in various metal cutting processes.Chatter prediction in cutting processes was the premise of chatter suppression.The theoretical method for chatter prediction,in-process recognition techniques for chatter prediction,and influencing factors for metal cutting dynamics were reviewed.Applications of machine tool structure materials were introduced.Some problems and research directions in future were proposed.
