Sažetak

EDM is effectively used in many application like aerospace, turbine, medical and etc., due to its non-contact process between work piece and tool. In this study, the important machining process parameters such as peak current, pulse on time, pulse off time and fluid pressure are inspected that incitement to distress the performance of the operation Material removal rate (MRR) and Tool wear rate (TWR). Subsequently tool geometry and materials that are predominantly affect the work piece response factor as Surface roughness (SR). Hence copper electrode with coating of brass material and different tool geometry are also considered. PH15-5 stainless steel precipitated hardening steel was machined up to 5 mm depth with EDM die sinking machine using 27 number of experiments designed.
