In electric discharge machining (EDM), to achieve better surface finish negative polarity (tool + ve, work -ve) was found as one of the prominent factors (Wu et al 2005).…”

Background: The machining of conductive alumina ceramic was successful by the electric discharge grinding (EDG). Therefore, the aim of the present work is to increase the material removal rate (MRR) during EDG of conductive alumina ceramic by addition of ceramic powder with dielectric. Methods: To achieve the objective through experimental investigation is carried out and the influence of input process parameters (powder concentration, duty ratio, pulse on time, table speed and wheel speed) on surface roughness (SR), MRR and surface integrity has been studied. The fine grade silicon carbide powder of #1000 mesh sizes was mixed in dielectric medium with varying concentration to understand the influence of the powder concentration and its interaction with other process parameters during powder mixed electric discharge grinding (PMEDG). The central composite rotatable design (CCRD) has been used to plan the experiments. Optimization of the obtained statistical models of MRR and SR has been done to obtain highest MRR and lowest SR. Result: It was observed that the MRR achieved by PMEDG was 3 -10 times higher than EDG. It was found that all the process factors and interactions show significant contribution on SR. The SR obtained by PMEDG was 2 -4 times higher than EDG. Conclusions: It has been established that the PMEDG process is a better option for processing of Al 2 O 3 -SiC w -TiC ceramic material as preliminary operation before EDG to achieve high MRR. In the present work the surface and subsurface damages were also assessed and characterized by the scanning electron microscope (SEM).

“…For improving the process performance the semi conductive powder particles are suspended into the dielectric fluid during electro discharge machining (Kumar et al, 2010;Singh et al, 2011). Kansal et al (2005Kansal et al ( , 2007 studied the machining performance of AISI D2 and EN31 steel when silicon powder was suspended in the kerosene dielectric and reported a significant improvement in terms of material removal and surface finish.

“…In EDM, electrical conductive metals with sufficient toughness and irrespective of its hardness can be manufactured by using shaped tools in the presence of dielectric fluid to produce complex cavities in dies and moulds, which are otherwise difficult to create by conventional machining processes [2]. The recent developments in the field of EDM have progressed due to the growing application of EDM process for machining of complex arrayed structures [3].…”

Abstract:In the last few years, industries have been facing challenges to fabricate the complex shaped geometries and arrayed structures on difficult to cut materials. Recently, various researchers have successfully applied reverse electro-discharge machining (R-EDM) process for manufacturing of the arrayed structures at micro-level. In this paper an attempt has been made to check the feasibility of R-EDM for manufacturing the arrayed structure at macro-level and used it as a tool electrode in normal EDM. Effects of process variables likepulse current, gap voltage and pulse ON time are analyzed through the variation of material removal rate (MRR), tool wear rate (TWR) and surface roughness. Discharge current found to be an influential parameter which affects the MRR and TWR severely in both variants of EDM i.e. R-EDM and normal EDM.
