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.
