摘　　要：通过建立300M超高强度钢(低合金超高强度钢40CrNi2Si2MoVA)高速铣削切削力经验模型,分析切削参数对切削力的影响,为高速铣削切削参数的合理选择提供可靠依据。采用多因素正交试验方法进行300M超高强度钢高速铣削实验,使用最小二乘法等概率统计方法和回归分析原理建立切削力与轴向切深、主轴转速、进给量、径向切深之间的经验模型,对回归方程及回归系数进行显著性检验,通过切削参数优化验证切削力模型的有效性。通过正交试验直观分析考察切削参数对于铣削力的影响规律。An empirical cutting force model is presented to estimate the influence of milling parameters on milling forces in the case of high-speed milling of 300M ultra-high-strength steel （low alloy ultra-high-strength steel 40CrNi2Si2MoVA）. The empirical relationship between the cutting force and the cutting parameters is given. Also, factors such as speed, feed and depth of cut collected from the experiment are examined by using both statistic analysis and regression analysis. The model of cutting force is validated by the optimization of cutting parameters. The influences of milling parameters on milling forces are investigated through analyzing orthogonal experimental curves.
