Abstract: An optimization method was presented to obtain the track parameters of Wire Electric Machining (WEM) in processing the auto-closed cut on the ring with high precision. Firstly, the 5 three-dimensional models of the motion space of wire were gained by WEM and on Auto CAD software. Then, 7 track parameters were defined, and the influence of the position parameter by auto-closed cut on other six parameters was discussed. And the control condition affecting track parameters were analyzed. Finally, the relationship between the track parameters and fitting performance were established. The results showed with increasing of fitting area, the 6 other track parameters had significant changes, and the stability decreased. It was concluded that the optimization method and track data could be applied in the design and manufacturing of the electric spark machining.
