Machining (EDM) process with multiple performance characteristics based on orthogonal
array with the Grey relational analysis was studied. The Grey relational analysis
theory was used to resolve the complicated interrelationships among the multiple
performance characteristics. In the present study, attempt was made to find
the optimal machining conditions under which a blind-hole can be drilled using
a multihole electrode. The Taguchi method was used to determine the relations
between machining parameters and process characteristics. In this study, the
machining parameters, namely electrode polarity, discharge current, pulse on
time, pulse off time and dielectric pressure were optimized with considerations
of multiple performance characteristics including machining time, electrode
wear and surface roughness. Experimental results showed that machining performance
in the EDM process can be improved effectively through this approach.]]>Manna, A. and B. Bhattacharya,200525850856Ozben, T., E. Kilickap and O. Cakir,2008198220225Muthukrishnan, N., M.
