  • Material Removal Rate Electrode Wear Rate And Surface

    electrical discharge machining is one of the earliest nontraditional machining, extensively used in industry for processing of parts having unusual profiles with reasonable precision. In the present work, an attempt has been made to model material removal rate, electrode wear rate, and surface roughness through response surface methodology in a die sinking edm process.figure wear on copper and brass for the edg using brass as electrode, from electrode after the edg process anova analysis, the best signiicant factors are ON time, peak current and capacitance factor gives 3.1 surface roughness cumulatively contributes factor about 85.83% for result of surface roughness using copper and surface roughness.
