Description
Summary:The process of electrical discharge machining (EDM) is one of the modern machining processes that machining stiff and high-strength parts such as ceramics and heat-treated steels, which traditional methods cannot be successful in their materials removal, is the most important applications of the this process. Deep drilling, machining inclined surfaces and small-scaled machining are the other applications of this process. Despite the unique applications of this method of machining, low materials removal rate (MRR), high surface roughness (SR), high tool wear rate (TWR), formation of recast layer on workpieces surfaces (that is location of defects and cracks) and environmental problems are the main problems and limitations of this process. This paper reviews the current research trends in EDM process containing dry EDM, near dry EDM, magnetic field assisted EDM, ultrasonic vibrations assisted EDM, and powder mixed EDM processes which were developed in order to overcome the limitations of EDM process.
