A review on current research trends in electrical discharge machining (EDM)

Effects of Wire EDM on the Microstructure of P/M Titanium Samples

“…The temperature of the area under spark increases. As a result, the materials melt and vaporize from localized area by using spark energy (15)(16)(17).…”

“…Thus, CP Ti is classified as "difficult-to-machine" material. Therefore, unconventional machining processes, including wire EDM (WEDM) are introduced for machining CP Ti (16)(17)(18).…”

Thermal Decomposition of Epoxy Resin Contained in Printed Circuit Boards from Reactive Dynamics Using the ReaxFF Reactive Force Field

“…高压电脉冲技术为废弃电路板的处理提供了新的 出路. 在高压电脉冲的作用下, 不同材料之间的界面附 近的电场增强, 引发介质雪崩式电离形成等离子放电通 道 [9,10] . 放电通道产生膨胀, 当膨胀产生的力大于材料 的抗拉伸强度时, 会使材料破裂.…”

Effect of Electrode Materials on Electric Discharge Machining of 316 L and 17 - 4 PH Stainless Steels

“…The effect of machining parameters on material removal rate, electrode wear rate, surface quality and diametric over-cut on tool steels were investigated in detail and concluded that copper and graphite electrode resulted in the best machining rate [4]. Mohd Abbas et al presented the current research trends on machining and modeling techniques in predicting EDM performances [5]. Luis et al had re-ported that the material removal rate and electrode wear in die sinking EDM of silicon carbide and conductive ceramics using copper electrode by applying design of experiments [6].…”
