摘　　要：采用正交试验的方法对压铸镁合金AZ91D进行了钻削试验,用多元线性回归法对试验结果进行了处理,建立了压铸镁合金AZ91D的钻削力与扭矩的经验公式。由经验公式可以确定:对钻削力和扭矩影响最大的是钻头直径 d,进给量 f次之,切削速度 v的影响最小。因此在实际生产中可以采用提高转速的办法来提高加工效率,减少能耗。Drilling experiments were carried out for the die cast magnesium alloy AZ91D using the orthogonal experiment. The results were dealt with multiple linear regression. Experiential formula of drilling force and torque moment was established. Experiential formula indicates that the effect of the aiguille diameter on drilling force and torque moment is maximal ,feed level takes second place and cutting speed is minimal. Therefore increase the cutting speed can improve the efficiency of machining and reduce the energy consumption in practical production.
