Abstract

In this project, Response Surface Methodology (RSM) is used to investigate the effect of three important EDM parameters those are namely: discharge current(Ip), pulse-on-time(Ton) and gap voltage(V) on Surface Roughness (Ra) of on Electrical Discharge Machined surface. In this study a second-order polynomial model is used and taken help of and using the central composite design (CCD) which estimates the
model coecients of the three factors that infuences surface roughness of work-piece in EDM process.A experiment was well designed and it was used to reduce the total number of experiments.Experiment was done on mild steel and copper was used as tool.The response is modeled using RSM on experimental values obtained.It was found that discharge current(Ip) and pulse-on-time(Ton) have signicant eect on
surface roughness whereas gap voltage(V) is less signicant.
