一、前言 根据韦伯斯特大辞典,高频振荡(Chatter)的定义是“切削过程中的高速振动”。这种振动对于使用镗刀杆进行深孔加工的人是深感头痛的问题。 镗削过程中防止产生高频振荡的方法之一,是提高镗刀杆的动刚度。本文基于此观点,对镗刀杆的设计、选择问题进行探讨。 二、有关镗 I. Preface According to the Webster Dictionary, the definition of high-frequency oscillation (Chatter) is “high-speed vibration during cutting.” This vibration is a serious headache for those who use boring bars for deep hole machining. One of the ways to prevent high frequency oscillation during boring is to increase the dynamic rigidity of the boring bar. Based on this view, this article discusses the design and selection of boring bar. Second, the boring
