Comparative study of different dielectrics for micro-EDM performance during microhole machining of Ti-6Al-4V alloy
TL;DR: In this paper, the impact of different types of dielectrics on the performance of micro-EDM machining was investigated using scanning electron microscope (SEM) micrographs and optical photographs.
Journal ArticleDOI
Investigation of electro-discharge micro-machining of titanium super alloy
TL;DR: In this article, the performance of micro-electro-discharge machining of titanium alloys has been evaluated using the Taguchi method and the ANOVA and S/N ratio graph.
Journal ArticleDOI
Parametric analysis on electrochemical discharge machining of silicon nitride ceramics
TL;DR: In this paper, the authors developed a second order non-linear mathematical model for establishing the relationship among machining parameters, such as applied voltage, electrolyte concentration and inter-electrode gap, with the dominant machining process criteria, namely material removal rate (MRR), radial overcut (ROC) and thickness of heat affected zone (HAZ), during an ECDM operation on silicon nitride.
Journal ArticleDOI
Performance of ZrB2-Cu composite as an EDM electrode
Asit Kumar Khanra,B. R. Sarkar,Bimalendu B. Bhattacharya,Lokesh Chandra Pathak,M.M. Godkhindi +4 more
TL;DR: In this paper, a metal matrix composite (ZrB2-Cu) was developed by adding different amounts of Cu and tested as a tool material at different process parameters of EDM during machining of mild steel.
Journal ArticleDOI
Modelling and analysis of EDMED job surface integrity
TL;DR: In this paper, a comprehensive mathematical model based on Response Surface Methodology (RSM) was developed for correlating the interactive and higher-order influences of major machining parameters i.e. peak current and pulse-on-duration on different aspects of surface integrity of M2 Die Steel machined through EDM.
