Modeling and Multiresponse Optimization of Quality Characteristics for the Micro-EDM Drilling Process

An Influence of Parameters of Micro-electrical Discharge Machining on Wear of Tool Electrode

“…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].…”

“…The unique capabilities of micro-EDM-based processes and the correlation between the process performance outputs and the input process settings has been explored in detail by many researchers [21][22][23][24][25][26][27][28][29][30][31][32]. Kim et.…”

“…Furthermore, Amorim et al [28] have analyzed the effect of generator actuation modes and micro-EDM controllable factors on the quality of machined surfaces. Natarajan et al [29] has carried out a detailed micro-ED hole drilling experimentation to evaluate the surface roughness, material removal rate and tool wear ratio. The optimum parametric conditions were identified and the optimum values of material removal rate, tool wear ratio and surface roughness of 0.019 mm 3 /min, 0.52 µm and 1.18 were respectively obtained.…”

“…Furthermore, LIGA technique and micro-EDM techniques were combined aiming at generation of high aspect ratio micro-features [32]. It is based on conception elaborated by authors of the paper [29].…”

“…One of the recent studies [29] have demonstrated the capabilities of the process and evaluated the process outputs, however, the research issue concerning tool electrode wear remains unsolved. Therefore, the objective of this paper is to present an altered discussion on the results of tool wear ratio through a systematic modeling and analysis approach.…”
