Summary: | Using hydrocarbon oils as a flushing medium causes lots of issues to machinists such as cancer. In this study, the behavior of green flushing medium (SF biodiesel and deionized water) during µED milling of hybrid metal matrix composites (HMMC) under various parametric settings of reinforcement wt%, capacitance and feed rate is analyzed. Metal erosion rate (MER) decreases with rise in capacitance due to longer interval between sparks. Higher MER is attained with lower order wt % reinforcement whereas the surface roughness increases increment in wt % reinforcement. S
