摘　　要：针对钛合金进行干式车削实验,通过单因素实验法,研究了切削用量中切削速度、进给量和切削深度单独变化对切削振动的影响.研究结果表明:随着切削速度的上升,切削振动加速度先上升后下降再上升;随着进给量变大,切削振动加速度也变大;切削振动加速度随着切削深度的增大而增大,当切削深度达到某个限度时,切削振动加速度开始减小.In this paper,through the dry turning test of titanium alloy,the influence of cutting vibration is studied by single factor analysis method,and the law of cutting vibration during the cutting dosage changing is analyzed.The results show that with the increase of cutting speed,the change trend of cutting vibration acceleration increases,decreases and then increases again.As the feed rate becomes larger,the cutting vibration acceleration also becomes larger.The cutting vibration acceleration increases with the increase of back feeding amount,but the cutting vibration starts to decrease when reaching a certain limit of back feeding amount.
