| 摘 要： | 以铣削为对象,建立了2自由度的铣削加工颤振动力学模型,分析了铣削颤振的产生机理;在此基础上,提出了基于电流信号的铣削颤振检测识别模型,该模型利用主轴电流信号的高频成分和低频成分的相对变化,很好地识别出颤振的发生,同时,该方法有效地消除了切削条件变化对检测结果的影响.此外,该方法算法简单,计算量小,可以实现实时检测.

| Abstract: | A dynamic model of chatter with twodegree of freedom for milling process is presented, and the mechanism of chatter is analyzised. On the basis of these, the model of detecting the chatter based on current signal is given, which uses the boo of high frequent and low frequent of current signal of spindle. The method which can detects the chatter reliably eliminates the effect of changes of manufacturing conic on the results of detection. Besides these, the arithmetic is simple, and it is carried out real-the for its small for of calculating. |
