Electrical Discharge MachiningOptimization Of Chromium Powder Mixed Edm Parameters During Machining Of H Tool Steel

In The Present Study, Optimization Of Chromium Powder Mixed Edm Parameters Is Studied During Machining Of H Tool SteelFour Input Parameters Of Powder Mixed Edm, Namely Peak Current, Pulse On Time, Duty Cycle And Powder Concentration, Are Varied, Each At Three Levels, To Get The Optimum ResponsesMaterial Removal Rate mrr, Tool Wear Rate twr And Surface Roughness ra Are Considered As Performance MeasuresCopper Electrode Of Mm Is Used As The ToolResponse Surface Methodology Is Used To Correlate Input And Output ParametersThe Variation Of Responses Due To Variation In Input Parameters Has Been Studied And Shown In The Form Of Surface Plots And Contour Plots.
