An Experimental Investigation During Electric Discharge Machining of Tool Steel-D2
Keywords:
EDM, MRR, RSM, Tool SteelAbstract
Electrical Discharge Machining (EDM) is the one of the earliest nontraditional machining processes. Today, many parts used in the aerospace and automotive industries and in the final processes of surgical can be finished by the EDM process. The machining parameters mainly affect the economy of process. This work emphasizes to find the optimization of machining parameters using response surface methodology (RSM)
by variation of peak current, pulse time variation so that good Surface Finish (SF) can be achieved with the optimum Material Removal Rate (MRR). It was concluded that with the increasing peak current and pulse
on Time (Ton), MRR increases but the surface roughness also starts to increase resulted in poor surface finish whereas with decreasing the pulse off Time (Toff), the surface finish increases but MRR starts to decrease. During the experimentation, Tool Steel-D2 was selected as work specimen with the copper electrode. Surface micrography had been done for the deep analysis to see the effect of machining on the Tool Steel-D2. This study indicates towards the practical feasibility of optimized EDM parameters in multi response conditions.
