초록
The purpose of this study was to present the method to choose the optimization machining condition for the wire electric discharge machine. This was completed by examining the ever-changing quality of the material and by improving the function of the wire electric discharge machine. Precision metal mold products and the unmanned wire electric discharge machining system were used and then applied in industrial fields. This experiment uses the wire electric discharge machine with brass wire electrode of 0.25mm. In this experiment, we changed no-node voltage to 7 and 9, pulse-on-time to 6$mutextrm{s}$, 8$mutextrm{s}$ and 10$mutextrm{s}$, pulse-off-time to 8$mutextrm{s}$, 10$mutextrm{s}$ and 13$mutextrm{s}$, and experimented on wire tension at room temperature by 1000gf, 1200gf, and 1400gf, respectively.
