Nontraditional manufacturing (NTM) involves nontraditional transport phenomena and often nontraditional media. Thermally based energy transfer is the main material removal mechanism for several nontraditional machining processes including electrical discharge machining (EDM) and laser machining (LM). Thermal phenomena are also central in processes such as laser forming and direct metal depositi...

Electrical Discharge Machining (EDM) is a well-known machining technique since more than fifty years. Its principle is to use the eroding effect on the electrodes of successive electric spark discharges created in a dielectric liquid. EDM is nowadays widely-used in a large number of industrial areas. Nevertheless, few studies have been done on the discharge itself and on the plasma created duri...

Grey relational analyses are applied to determine the suitable selection of machining parameters for Wire Electrical Discharge Machining (Wire-EDM) process. The Grey theory can provide a solution of a system in which the model is unsure or the information is incomplete. Besides, it provides an efficient solution to the uncertainty, multi-input and discrete data problem. According to the Taguchi...

Electrical discharge machining (EDM) is highly utilized in manufacturing sectors owing to its ability to machine high strength materials with complex shape.
