摘　　要：通过分析摆轴式电火花小孔机的结构特点,结合三维空间建模软件,对航空发动机矢量小孔位置进行坐标重构,寻找空间坐标变换矩阵,从而将笛卡尔理论坐标系统变化为适应机床的多坐标系统,实现三维空间小孔的加工。并引入修正矩阵,减小了装配过程引进的误差。利用巧妙的工装设计方案,消除了小孔加工出口处的烧蚀问题。By analyzing the structure characteristics of pendulum shaft type small hole drilling electro-discharge machines,combined with three-dimensional modeling software,the coordinates of vector hole in parts of aircraft engine are refactored. Space coordinate transformation matrix is found out, and by it ,cartesian coordinate system is transformed the coordinate system in machine. The three- dimensional holes machining is expressed. The fitting error of fixture is reduced by correction matrix. Through the tooling design ,the ablation in export of the holes is eliminated.
