Study of Electrical Discharge Machining Process for EN-31 Tool Steel
Subscribe/Renew Journal
Electrical Discharge Machining (EDM), as a production process, has influenced its existence in variety of fields and industries during the recent years. Other than tool & die making, it has occupied the area of production of parts in aerospace, medical, optical, automotive, gauge making templates, standards, electronics, cutting tools, ceramics, composites and nuclear industries, working on and almost all advance materials. The most important performance measure in EDM is the Surface Roughness (SR); among other measures Material Removal Rate (MRR) and Tool Wear Ratio (TWR) could be listed. In this study, experiments were performed to determine parameters effecting SR along with structural analysis of surfaces with respect to material removal parameters. Experimental work has been conducted on EN-31 tool steel with copper, brass and graphite as the tool electrodes with kerosene oil as dielectric fluid. The data compiled during the experimentation has been used to yield the responses in respect of MRR and SR. Further, the detailed analysis of structural features of machined surface has been done by using Scanning Electron Microscope (SEM) to understand the mode of Heat Affected Zone (HAZ). The present paper highlights a practical approach for full exploitation of EDM capabilities.
