| Abstract: | This study presents optimization of multiple
performance characteristics [material removal rate (MRR), tool wear rate (TWR),
and overcut (OC)] in micro electrical discharge machining (micro-EDM) using
Taguchi method and Grey relational analysis. Machining process parameters
selected were pulse-on time, discharge current, and
gap voltage. Based on ANOVA, pulse-on time is found the most significant
factor, which affects micro-EDM process. Optimized process parameters
simultaneously leading to a higher MRR, lower TWR, and lower OC are then
verified through a confirmation experiment. Validation experiment shows an
improved MRR (12.88%), TWR (14.57%) and OC (6.1%) when Taguchi method and grey
relational analysis were used. |
