- Abstract
- Material removal rate (MRR) and surface roughness (Ra) of sink electric discharge machining (EDM) were investigated using experimental design and discharge energy method. This study is focused on the effects of the peak current, on time, and off time, during the discharging of the HP4MA material. Mathematical models were developed for the prediction of the Ra and MRR based on the response surface methodology (RSM). was proposed using the discharge energy method that was compared to the RSM model and the experimental results. The results indicated that both models can be used to predict the MRR and Ra of the EDM accurately.
