摘要：通过仿真研究高强度钢的切削力，建立高强度钢切削力的仿真模型。在AdvantEdge有限元仿真软件的基础上，运用正交试验方案分析切削用量对主切削力、进给抗力的影响规律，获得了该研究范围内切削用量的最优方案，建立了经验公式。结果表明，切削力仿真模型精度较好，切削深度对高强度钢切削力影响最大，主切削力和进给抗力均随切削速度的增大而减小，且主切削力Fc约为进给抗力Ff的两倍。

Abstract:Through the simulation research of highstrength steel cutting force，the simulation model of cutting force of highstrength steel is established.Based on the AdvantEdge finite element simulation software，using the orthogonal simulation method to analyze the influence of cutting parameters on main cutting force and feed resistance，the optimal scheme of cutting parameters in the research range is obtained，and the empirical formula is established.The results show that the cutting force simulation model is accurate，the cutting depth has the greatest influence on the cutting force of highstrength steel，the main cutting force and feed resistance are decreased with the increase of cutting speed，and the main cutting force Fc is about twice of the feed resistance Ff.
