摘　　要：采用Abaqus有限元分析软件,对CBN刀具切削H13淬硬钢的加工过程进行了仿真,分析了切削过程中工件的等效应力分布变化及切削力的特性。设计单因素对照试验,分析了切削力与各工艺参数(切削速度、背吃刀量、刀具前角、刀具后角)之间的联系;利用正交试验,研究了工艺参数对切削力影响的主次关系。结果表明,在一定参数范围内,使用较高的切削速度和较深的背吃刀量会导致切削力增大,适量增大刀具的前、后角有利于降低加工过程中的切削力;各因素对切削力影响的显著程度为:背吃刀量>切削速度>刀具前角>刀具后角。Using Abaqus finite element analysis software,the machining process of CBN cutting H13 quenched steel was simulated,and the changes in equivalent stress distribution of the workpiece and the characteristics of cutting force during the cutting process were analyzed.A single factor controlled experiment was designed to analyze the relationship between cutting force and various process parameters(cutting speed,back cutting amount,tool rake angle,tool rake angle);The primary and secondary relationship between process parameters and cutting force was studied using orthogonal experiments.The results indicate that within a certain parameter range,using higher cutting speeds and deeper back cutting amounts will lead to an increase in cutting force.Increasing the front and back angles of the tool appropriately is beneficial for reducing cutting force during the machining process;The significant degree of influence of various factors on cutting force is:back cutting amount>cutting speed>tool rake angle>tool rake angle.
