A Literature Review on Modeling and Simulation of Crater Dimension in Electrical Discharge Machining

Abstract

A comprehensive model of electrical discharge machining has been used for simulating the crater size during the process for materials Aluminum, Brass and die steel D2. It is very difficult by theoretically to analysis temperature distribution in whole work -piece because of its complexity process and a single discharge is occurs very short time. A novel model proposed with realistic condition such as plasma radius, Gaussian heat flux and temperature dependent properties and this model use software ABAQUS 6.2. In this work piece crater diameter and depth is predicted on the basis of simulation. FEM model show the variation of crater size (temperature distribution) with variation in input parameter. In model, increasing discharge energy causes crater size increase means MRR and surface roughness increases. In this model, simulation show better result with experimental result and error is taken under consideration like 13 to 20% which is better result in present research scenario.
