| Abstract: | The newest trends of electrical discharge machining(EDM) including die-sinking EDM,micro EDM and wire EDM(WEDM) in Japan were presented.A new technique,high speed dry EDM milling of 3D cavities together with its principle,the apparatus and the machined effect,was introduced in die-sinking EDM.A newly developed machining system that can be simultaneously used to machine both microelectrodes/micropins and microholes,and the minimum rod size it can machine currently were presented in micro-EDM.A new approach to improving the accuracy of corner cuts,a new method of improving controllability of discharge locations and a new method of slicing silicon ingots were illustrated in WEDM. |
