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。

关键词: 金属切削, 颤振预测, 材料, 时滞, 稳定性分析

Abstract: 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. 

Key words:  , metal cutting, chatter prediction, material, time delay, stability analysis
