| Abstract: | Firstly, the basic theory of designing the electrode of EDM finishing manufacturing intricacy stream hole parts is described in this paper. By means of the postulate of forming conjugate surface in generating stream hole and using the concept of curvature interference in differential geometry to design the free- interference electrode of EDM finishing manufacturing .the movement contrail,position and attitude of electrode of EDM finishing manufacturing is obtained. At the same time, a special kind of CAD/CAM software is designed. Lastly, the feasibility and validity of this inaugurate method is validated through simulating some examples. |
