Abstract


The surface quality is an important phenomenon in any metal cutting processes. This paper experimentally investigates and discusses EDM machining of P20 die steel using copper electrode. The process parameters (discharge current, pulse on and off time) which influences the surface roughness was determined. Response surface methodology is used to develop a mathematical model the effect of input parameters on Surface roughness. The developed mathematical model is a second order equation of input parameters.

Keywords: Spark erosion Electric Discharge machine, Mathematical modelling, Central composite Design of Experiments, Response surface methodology, surface roughness
