切削振颤的预报控制

Predictive control of cuting chatter

讨论了切削振颤的预报控制方法 ,在充分研究车削加工振动信号变化规律的基础上 ,提出了用特征参数Pa作为切削振颤的预报参数 ,并进行了有监测切削和无监测切削的对比试验。试验结果表明 。

The predictive control of cutting chatter is mainly discussed in this paper.On the basis of making a full study of varying regularity of vibration signal at the center of turning process the characteristic parameter Pa is presented as the predictive parameter.The experiment of contrasting on line monitor with non on line monitor is made.The result shows that the on line monitor control will brings the stability of turnng into a striking effect.
