摘　　要：介绍了高灵敏度的微小孔钻削测力仪的结构设计及微小孔钻削力测量系统的工作原理。通过多元正交多项式回归实验 ,得到了微小孔振动钻削力关于振动频率、振幅和进给量的非线性回归方程 ,进而分析了振动参数和切削参数对钻削力的影响 。The structural design of a high sensitive micro hole drilling dynamometer and the working principle of the micro hole drilling force measuring system are introduced. Based on the experiment of multi element orthogonal polynomial regression, the nonlinear equations of drilling force in terms of vibration frequency F , vibration amplitude A and feed f are obtained. Moreover, the effects of vibration parameters and cutting parameters on drilling force are analyzed. Thus the necessary experiment instrument and the valuable research method are provided for the further research on micro hole vibration drilling.
