EDM, Electrode Shapes, DOE, Parameter Analysis


The objective of this research is to study the influence of Process parameters and electrode shape configuration on the Machining characteristics of die sinking EDM. The present work aims to study the effect of different electrode shapes (Circular, rectangular and triangular) With constant cross sectional area of 280 mm2 on material removal rate (MRR), surface roughness (SR) and Electrode wear rate (EWR) for AISI P20 tool steel workpiece material and pure copper As electrode material. The optimization of the parameters of the EDM machining will be carried out by using the taguchi’s method for design of experiments (DOE). The objective of the analysis is to identify the Optimum electrode shapes in terms of higher MRR, minimum EWR and excellent surface finish. The different parameters considered while carrying out the experiments on the Die-Sinking EDM will be the current applied, pulse on time and pulse off time required etc.
