Performance analysis of modified ISO Energy pulse generator on Machinability in EDM process

Abstract

In aerospace and automobile engineering field high hardness newlinematerials can be easily machined by electrical discharge machining EDM newlineprocess with complex shapes Electric discharge machining is a material newlineremoval procedure by means of electrical energy due to the repetitive spark newlinedischarges This erosion process has stochastic nature of machining due to the newlinerandom distribution of spark energy over the surface A lot of process newlinemechanism enhancements are needed to nullify the non linear nature of the newlineEDM process newlineSince the applied DC pulses are determining the machining newlinecharacteristics in EDM process, it is important to enhance the performance of newlinethe pulse generator Owing to its ability of producing larger crater volume newlinewith random energy distribution the transistor pulse generator can produce newlinepoor surface finish with higher material removal rate The conventional RC newlinepulse generator can produce good surface quality by producing tiny crater on newlinethe machined surface Nevertheless it can remove material with less erosion newlinerate In the present study an attempt has been made to develop an iso energy newlinepulse generator for improving machining characteristics with less arcing newlinenature and to investigate its influence on performance measures of erosion newlineprocess newline newline
