ANALYSIS OF MRR OF TOOL STEEL MATERIAL ON EDM FOR DIFFERENT ELECTRODE MATERIALS

Electrical Discharge Machining is a technological process with a large industrial implementation. Its use is particularly intense when very complex shapes on hard and brittle material with high geometrical and dimensional accuracy are required. Material Removal Rate, Tool Wear Rate and Surface Finish are most important parameters, which decide machining performance. Present study attempts to find out electrodes performance in electric discharge machine (EDM). In this work, the effect of different electrodes performance with different input with their different levels in EDM on machining characteristics of cold work tool steel has been studied. Three parameters are electrode Materials, Peak current and pulse on time. The process performance is measured in terms of Material Removal Rate (MRR). The result outcome will identify the important parameters and their effect on MRR in the presence of dielectric fluid in EDM
