摘　　要：为研究切削速度和进给量对镍基合金GH4169切削时的影响,利用有无轴向超声振动对镍基合金GH4169切削时的切削力、切削温度、表面粗糙度和刀具磨损进行车削试验。结果表明:超声振动能够减缓切屑锯齿化程度;超声振动切削力远低于普通车削,当速度增大时2种加工方式下切削力逐渐靠近;进给量与切削温度、粗糙度和切削力呈正相关;切削速度的增大使得切削温度和表面粗糙度也不断升高,且超声振动切削温度和表面粗糙度显著较低。In order to explore the influence of cutting speed and feed rate on the cutting of nickel-based alloy GH4169, the cutting force, cutting temperature, surface roughness and tool wear of nickel-based alloy GH4169 were studied by turning tests with or without axial ultrasonic vibration. The test results show that ultrasonic vibration can reduce the degree of chip sawtooth;ultrasonic vibration cutting force is much lower than ordinary turning, when the speed increases, the cutting force under the two processing methods gradually approaches;the feed rate is positively correlated to the cutting temperature, roughness and cutting force;the increase in cutting speed makes the cutting temperature and surface roughness continue to rise, and the ultrasonic vibration cutting temperature and surface roughness are significantly lower.
