A Review on Optimization of Micro EDM Machining Performances

Now these days there is a massive requirement in the production of microstructures by a unconventional method. Micro-EDM (µEDM) is a widely accepted unconventional machining option in which material erosion takes place from work-piece using a sequence of electrical spark. This method is used to manufacture micro-parts with the range of 50 μm -100 μm. This paper studied the optimization of various process parameters namely gap voltage, peak current and pulse duration to attain suitable µEDM performance measures such as Material Removal Rate (MRR), low Electrode Wear (EW) and good surface morphology of the microstructure accepted from µEDM machining process.
