摘　　要：枪钻轴向振动钻削深孔的过程中,钻削力的变化情况复杂,且对深孔的加工质量、刀具的磨损度都有影响,尤其是轴向力和扭矩。为了获得枪钻轴向振动钻孔的轴向力和扭矩受振动参数的影响规律,运用正交试验,结合有限元模拟软件Deform-3D,对枪钻钻头轴向振动钻孔过程进行正交仿真试验,并用多元线性回归法对试验数据进行分析,建立起轴向力和扭矩的回归经验公式。In the deep hole cutting process of axial vibration drilling by gun drill,the changes of cutting forces are complex,it has a critical impact for the quality of deep hole and the wear of tool,especially for the axial force and torque.In order to obtain the influence rule of axial force and torque by vibration parameters in axial vibration,using orthogonal test,based on the finite element simulation software Deform-3D,make a orthogonal simulation experiment for the gun drill axial vibrating drilling and analysis the experimentdata by multiple linear regression method,establish the regression axial force and torque. process, model of
