A Review on Electric Discharge Machining with Assisted Processes for Precise Machining of Hard to Cut Materials
摘要
The benefits conferred by the integration of two or more machining methodologies can be amalgamated within hybrid machining processes. The underpinning of hybrid machining methodologies is the controlled, concurrent engagement of machining techniques, energy modalities, and implements that profoundly influence process efficacy to exploit benefits and transcend the constraints of discrete constituent processes. The amalgamation of hybrid machining methodologies, such as Laser-Assisted Machining in conjunction with Electric Discharge Machining (EDM), Magnetic Field-Assisted EDM, Vibration-Assisted EDM, as well as Electrochemical Discharge Machining (ECDM), alongside Abrasive Water Jet Machining, Abrasive-Aided EDM, and Abrasive-Assisted Electro-Chemical Machining (ECM), exemplifies the spectrum of Abrasive Assisted Advanced Machining (AAAM) technologies. Their basic ideas, uses, and most recent developments are discussed. Superior mechanical qualities, lightweight constructions, and high precision are always demanded by the aircraft sector for materials and components. Because of these exacting standards, machining technology, and especially unconventional hybrid machining methods, have come a long way. These procedures get over the drawbacks of traditional methods by combining the best features of various machining processes. Aerospace, automobile and complex geometry manufacturing have embraced non-traditional machining techniques like Electrical Discharge Machining (EDM), Laser Beam Machining (LBM), and Ultrasonic Machining (USM). When machining ceramics, composites, and high-strength alloys, these techniques come in handy. Material removal rates, surface finish quality, and tool wear are just a few examples of the limits that might be encountered with various non-conventional procedures. A solution to these problems that improves efficiency and accuracy is hybrid machining, which combines two or more machining techniques EDM.
