摘　　要：振动是金属切削加工过程中经常遇到的一种现象,也是影响零件加工质量和限制生产率提高的主要因素之一。本文在切削颤振机理研究的基础上,对切削颤振的二维稳定性进行了研究,推导出了在稳定性极限条件下,轴向切深和主轴转速的关系,并用Matlab进行了计算仿真。The regenerative chatter is one of the phenomena in the metal machining process, which also is one of primary factors that affect the processing quality and limits the productivity enhances. This paper studies the two-dimensional stability dy- nanties models for the chatter on the basis of cutting chatter principle, and infers out the relation of cutting depths and the rotation under the limit condition of stability, and uses Matlab to calculate and simulate.
