Abstract

In this study, machining performance of Tungsten carbide (WC) was investigated by modifying the Wire-cut electric discharge machining setup as turning process. The exclusive set up was fabricated for fixing the workmaterial and to facilitate rotating and linear motion constitutes a turning process. The experiment was conducted on Tungsten Carbide (WC) for 9 different trials by varying the input conditions of pulse on-time (T-on), pulse off-time (T-off), wire feed and wire tension to analyse the Material Removal Rate and Surface Roughness. The Taguchi method was used to optimise the process parameters for better Surface Finish and Maximum Material Removal Rate. The influences of process parameters on Material Removal Rate and Surface Roughness are statistically analyzed by ANOVA. The results revealed that the more important parameters are pulse on time (T-on) and pulse off time (T-on) than wire feed and wire tension. The best parameter was identified against response characteristics.
