摘　　要：为提高数控车削45~#调质钢的加工表面粗糙度,基于正交试验法和单因素试验法设计车削试验,通过极差和方差分析法对试验结果进行分析,研究切削用量三要素(切削速度、进给量和背吃刀量)对加工表面粗糙度的影响。结果表明:影响车削加工表面粗糙度的显著性参数依次为切削速度>背吃刀量>进给量;单因素试验法分析结果表明加工表面粗糙度随切削速度的增加而降低,随进给量和背吃刀量的增加而增大。In order to improve the surface roughness of NC turning 45~# quenched and tempered steel. The turning test w as designed based on the combination of orthogonal test and single factor test. The range method and variance method w ere used to analyse the influencing of three cutting factors( cutting speed,feed rate and cutting depth) on the surface roughness. The results show that the significant factors from high to low are the cutting speed,the cutting depth and the feed rate; The influencing of the three factors on the surface roughness is as follow s : The surface roughness decreases w ith the increasing of cutting speed,but increases w ith the amount of feed rate and the cutting depth.
