This process is used for complex shapes, which have sharp edges that are difficult to machine using conventional machining processes. SKD11 is used as a work piece and performance analysis is done to find out the significant control factors for SKD11 by using one factor approach at a time. In this research paper, effect of various control factors like pulse on time, pulse off time, servo voltage, peak current, water pressure, wire tension, wire feed, peak voltage and, servo feed on cutting rate has been investigated while machining on SKD11 using one variable at a time approach. Experiments show the response for different parameters on WEDM. Cutting rate increases as the pulse on time and peak current increases. Cutting rate decreases with the pulse off time and servo voltage increases. Wire feed and wire tension has no effect on cutting rate.
