Abstract : The present work uses a novel optimization technique combining PCA with quality loss concept for the selection
of best setting of Electro Chemical Discharge Machining (ECDM) parameters for minimum geometric hole characteristic
induced during drilling in drilling glass. Experiments were conducted with different drill, applied voltage, feed rate and
machining time each at three levels using L27 setting of the orthogonal arrays. The responses considered to evaluate the
geometric hole characteristic are Radial overcut (ROC), Circularity, and heat affected zone (HAZ). Principal component
generated the uncorrelated linear combinations of original response which then used to derive combined quality loss i.e.
hole geometry performance index (HGPI). Response table, response graph and the analysis of variance (ANOVA) were used
to determine the optimal setting and the influence of ECDM parameters on the HGPI. The results obtained from the above
analysis are validated by performing confirmation experiments.
