Electrical discharge machining (EDM) is extensively used unconventional machining process for making small holes, dies and cavity from past decades. Extremely hard material is easily machined without any vibration and chattering by EDM process.However, major problems encounterin the EDM process are poor surface quality and low material removal rate (MRR).These drawbacks have been overcome by progressive research in previous years. The paper aims about a review on the modern machining trends of EDM and to study the development of different hybrid EDM processes like ultrasonic assisted EDM, magnetic field assisted EDM, rheological fluid assisted EDM and powder mixed EDM. The study mainly prominenceson aspects related to material removal rate, tool wear and surface quality. Discharge current, pulse on time, pulse off time, duty cycle, voltage and percentage of abrasive particles were reported as the input parameters in existing research.
