摘　　要：为了分析油膜附水滴切削液(OoW)润滑时,影响切削力的关键因素以及最优的切削加工参数。运用田口实验方法,对45钢进行切削实验研究。运用方差分析方法和静态信噪比对采集的实验结果进行数据处理及分析。分析结果表明:背吃刀量ap、进给量f对切削力的变化有着高度显著性影响,切削速度V的改变对切削力有着显著性影响。通过田口方法的分析得到的最优切削参数为切深0.6mm,进给量0.08mm/r,转速120m/min,为今后实际工业生产中切削参数的优化提供了重要参考。In order to provide reference for cutting parameter optimization in practical industrial production,a research is made in which the orthogonal OoW turning tests of 45 steel were carried out on the C620-1 lathe using Taguchi method. The statistical method of signal to noise ratio(SNR)and the analysis of variance(ANOVA)are employed to investigate the effect of depth of cut,feed rate and cutting speed on cutting force. The result of this study shows that the changes of cut depth and feed rate have a significant impact of cutting force. By taguchi method it gets the optimal cutting parameters ap=0.6 mm,f=0.08 mm/r,V=120 m/min,and it provides an important reference for the industrial production.
