摘　　要：金属切削过程中刀具与工件间存在着剧烈的相对振动,这种振动称之为颤振,颤振影响加工质量,减少机床寿命,解决加工中的振动问题是制造行业关注的热点。在总结现有理论分析的基础上,针对某机床厂型号为VMC850E的加工中心,采用仿真的方式进行数学建模及分析找到铣削稳定区,以此为依据搭建一套机床颤振控制系统。Relative vibration between the tool and work pieces during metal cutting was distinguished as chatter,which not only in-fluenced the processing quality,but also reduced working life of the machine tool. To solve the problem of chatter in processing was the hot topic in the manufacturing industry. Based on theoretical analysis of the previous studies,aimed at the VMC850E machining center from one machine tool works,a machine tool chatter control system is set up,on the basis of milling stable region obtained through using simulation method for mathematical modeling and analysis.
