摘　　要：在切削液条件下采用单因素试验方法,进行涂层硬质合金立铣刀铣削GH4169试验,对比分析了切削用量对铣削振动的影响规律。试验结果表明:在试验条件范围内,单因素法改变切削用量对铣削振动的影响不同,铣削振动值从大到小分别为vx、vy、vz;切削速度vc与每齿进给量fz对铣削振动的影响较大;径向切削深度ae对铣削振动的影响不明显;轴向切削深度ap对铣削振动的影响显著。Under the condition of cutting fluid,single factor test method was used to mill GH4169 with coated carbide end mill,and the influence of cutting parameters on milling vibration was analyzed.The experimental results show that the influence of single factor method on milling vibration is different in the range of the experimental conditions,and the milling vibration values from large to small are vx,vy and vz respectively;the influence of cutting speed vc and feed rate fz is large;the influence of radial cutting depth ae is not obvious;the axial cutting depth ap has great influence on milling vibration.
