| Outline of Final Research Achievements |
For precise estimation of electrode wear in Electric Discharge Machining (EDM), preferable electric conditions had been identified with Design of Experiment Method, and a simulation system of electrode wear had been developed with geometric model of piled-disk for electrode and work. As Design of Experiment Method, L18 orthogonal table consisted of 8 factors with two or three levels had applied to identify the electric conditions of low electrode wear. In the simulation system of electrode wear, rate of electrode wear at a partial surface had been individually set and used.in the simulation. Because of changeable individual rate of electrode wear, the estimation accuracy of electrode wear was improved by 31 % compared with that of fixed rate. In comparison of estimation the error of electrode wear with straight tool path and circular-interpolated tool path on Contouring EDM, the latter path had a greater estimation error and the difference of both estimations was 0.31 mm in average.
