A Brief Study of the Particulate Matter Emissions During the EDM Process
Abstract Although Electric Discharge Machining (EDM) process fills a niche that it is often employed for the machining of hard and difficult-to-cut materials or for creating intricate features or textures, still the process produces byproducts in solid, liquid, gas, and aerosol form. The current study investigates the particulate material (PM) emissions of various sizes during the EDM process. The emissions include the airborne material particles from the tool and the workpiece materials and other by-products like hydrocarbons (HC) from the dielectric breakdown. The results show that there is a significant amount of PM emission during the EDM process. A portable aerosol spectrometer (PAS) has been used to measure the emissions ranging from 1.0 to 20.0 μ particle size, during the EDM process. Furthermore, the scanning electron microscope (SEM) images show the deposition of matter clusters on the PAS filter captured during the EDM process. The inductively coupled plasma mass spectroscopy (ICPMS) spectra also confirm the emission of various materials during the EDM process. The Energy Dispersive Spectroscopy (EDS) analysis shows the deposition of Carbon (C) 32.85%, Iron (Fe) 2.48%, Copper (Cu) 1.80%, Chromium (Cr) 0.21% and Nickel (Ni) 0.17% on the PAS filter surface.
