Abstract

Electro Discharge Machining (EDM) is an extensively used non-conventional process for material removal in die manufacturing and aerospace industries. The present work investigates the effect of process parameters like graphite powder concentration (Cp), peak current (Ip), pulse on time (Ton), duty cycle (DC) and gap voltage (Vg) on the performance characteristics of material removal rate (MRR), tool wear rate (TWR), surface roughness (SR) and recast layer thickness (RLT) during EDM and PMEDM of H-11 die steel. Taguchi’s L27 orthogonal array was used to carry out the experiments. Investigation of microstructures was done using scanning electron microscope (SEM) to examine alterations and defects on the machined surface.
