摘　　要：针对切削过程中产生的颤振现象,通过对机床的在线监测,将采样出的振动加速度信号进行数据处理,提出一种以方差和互相关系数作为综合判据的方法来判别颤振是否发生,并在MATLAB环境下仿真证明该方法的可行性。For solving the chatter vibration in cutting process, this paper bases on processing the vibration acceleration signals which is sampled by on - line monitoring the machine tool, then presents a method to judge the happening of chatter by the variance and the mutual correlation coefficient synthetically criteria. The method is proved by simulations in MATLAB environment.
