Investigation of Environment and Machining Aspects in Electrical Discharge Machining (EDM) Using Different Workpieces and Tool Electrode

Abstract:

Emission of toxic substances is the major occupational and environmental problem associated with this process. These emissions may cause adverse health effects to the operators and has the direct impact on the environment. The present investigation was conducted to study together the environmental and machining aspects of EDM process. The work aims to investigate the emission and machining parameters in EDM process using different workpiece material viz; like aluminum, mild steel and AISI-D3 tool steel with EDM 30 as a dielectric fluid and brass as a electrode. The results showed that the aluminium workpiece material gave a higher emission rate and MRR compared with mild steel and AISI D3 tool steel due to the low melting and boiling temperature. Among the process parameters, peak current and pulse duration was found to strongly affect the emission and performance aspects.
