“…In most of the recent investigations, the process characteristics and capabilities of micro-EDM have been studied and applied for several industrial applications [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. The stainless steels are characterized by the inherent luster, high corrosion resistance, strength, and therefore adequate attention has been allocated to the micro-EDM investigations on these class of materials [13][14][15][16][17][18][19][20].…”

“…Therefore, in order to resist quick consumption of the tool electrodes, a few researchers have attempted to fabricate electrodes using advanced techniques such as electrochemical deposition and multi-EDM grinding, however, were effective only to some extent [30,31]. Furthermore, LIGA technique and micro-EDM techniques were combined aiming at generation of high aspect ratio micro-features [32].…”

To achieve better precision of features generated using the micro-electrical discharge machining (micro-EDM), there is a necessity to minimize the wear of the tool electrode, because a change in the dimensions of the electrode is reflected directly or indirectly on the feature. This paper presents a novel modeling and analysis approach of the tool wear in micro-EDM using a systematic statistical method exemplifying the influences of capacitance, feed rate and voltage on the tool wear ratio. The association between tool wear ratio and the input factors is comprehended by using main effect plots, interaction effects and regression analysis. A maximum variation of four-fold in the tool wear ratio have been observed which indicated that the tool wear ratio varies significantly over the trials. As the capacitance increases from 1 to 10 nF, the increase in tool wear ratio is by 33%. An increase in voltage as well as capacitance would lead to an increase in the number of charged particles, the number of collisions among them, which further enhances the transfer of the proportion of heat energy to the tool surface. Furthermore, to model the tool wear phenomenon, a regression relationship between tool wear ratio and the process inputs has been developed.

“…Among the successful conventional and nonconventional methods, micro-electrical discharge machining (micro-EDM), a non-traditional technique, has been verified as one of the most efficient fabrication methods for micro-components. [1][2][3][4] Micro-EDM can manufacture 2½D and 3D micro components and generate micro scale features on larger components. Its non-contact process means there is no interaction between electrode and workpiece and allows for the machining of ductile, brittle, or super-hardened metallic materials.…”

Lately, the development of micro/nano-scale devices in optics, displays, communications, electronics, and fuel-cell industries has given rise to the advent of various micro-machining techniques for fabricating microstructures. Moreover, the demand for the fabrication of complicated microstructures increases constantly. Micro-EDM is one of many methods that has been used to successfully fabricate microstructures, hence the need for high-quality micro-electrode tools is also growing. There are several well-known fabrication techniques such as reverse electrical discharge machining and wire electrical discharge grinding. However, these are limited by low aspect ratio and lengthy fabrication time. In this paper, we propose a novel micro electrode fabrication process with low-cost, easy setup, and quick and flexible implementation compared to commonly used methods. Our approach is based on the electrochemical etching technique. In this technique, a tungsten wire is etched until we obtain a desired profile. Several experiments were carried out to analyze the etching parameters and to evaluate the accuracy of our proposed method. The results detailed the role of every key parameter such as applied voltage, ring diameter, oscillation speed, etc... And demonstrated that this method can be used to fabricate a desired micro-electrode in a 16-minute timeframe with an error of less than 7%.

“…Rozpatrując nowe materiały na mikroelektrody należy wziąć pod uwagę nie tylko to czy materiał jest przewodnikiem, ale również możliwość wykonania elektrod w odpowiednim zakresie wymiarowym. Niekiedy wykonanie samej elektrody narzędziowej jest trudne i wymaga wielu operacji [3][4][5]. Przygotowanie jednej mikroelektrody może trwać nawet kilkadziesiąt minut [6][7].…”
