摘　　要：用Abaqus有限元分析软件建立淬火态30CrNi2MoVA高强度钢的二维高速切削仿真模型,研究切削过程中工件的应力分布及边缘缺陷;采用单因素方案研究切削速度与切削深度对于主切削力的影响。研究表明,在稳定切削阶段,应力大小与方向基本保持不变,剪切角约45°,至切出端,剪切角变为负值,切削力减小;在稳定切削阶段,Fx随切削速度增加而增大的幅度较小;随切削深度增加,Fx线性增大,证明切削深度对Fx的影响更大。This paper employs the Abaqus finite element analysis software to establish the two-dimensional high-speed cutting simulation model of quenched 30CrNi2MoVA high-strength steel to study the stress distribution and edge defects of the workpiece during cutting,and adopts single factor method to study the effects of cutting speed and cutting depth on the main cutting force.The results show that during stable cutting stage,the magnitude and direction of the stress basically remains the same,the cutting angle keeps about 45°and finally changes to negative at the cutting out end,and the cutting force decreases;in the stable cutting stage,the increment of Fx with the increase of cutting speed is small;while Fx is increasing linearly with the increase of cutting depth,which proves that cutting depth has a greater impact on Fx.
