针对切削加工过程中容易出现颤振，导致零件表面加工质量降低，本文以铣削加工为研究对象，提出了基于小波包能谱熵的铣削颤振监测方法。信号的采集是一个连续的过程，为避免刀具不参与切削对这种方法的影响，本文提出基于铣削力幅值平方和的方法以识别刀具是否参与切削。试验结果表明，无论对于刀具是否参与切削的识别或者是否出现铣削颤振的监测都能有效的监测。

Cutting chatter is a self -excited vibration which is considered as one of the most important causes of poor surface machining quality.In order to monitor chatter in milling process,velvet wavelet packet energy entropy based meth-od is proposed.However,signal acquisition is a continual process.A cutting force amplitude sum of squares based method is used to identify cutting tool whether participate in the cutting.The experimental results prove that the effectiveness of the proposed method.
