The wire cut EDM is one of the most important machining process for technologists in the field of moulds, dies and in precision manufacturing .The wire electrical discharge machining producing parts with in very short period , the demand over the time increases extensively .So that an extensive research work has been carried out to optimize the parameters of the process by eliminating trial and...

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) can use soft tool electrodes to process hard workpieces achieve “soft against hard”, because it directly uses electrical energy and thermal remove metal materials. Then, generate complex features on harder materials meet the requirements of excellent surface quality. Since EDM involves many parameters, including non-electrical properties, is essential optimi...

In electrical discharge machining (EDM), gap control is the key to stable processing; plays a significant role in EDM. To determine influence of on material removal and melt pool movement, which are two fundamental issues EDM, high-speed photography molecular dynamics (MD) simulations were used study process. Research results demonstrate that has during A smaller width produces more larger remo...

Traditionally, electrical discharge machining (EDM) or conventional laser tools have been used to manufacture a range of precision medical devices. However, these manufacturing methods cannot be used to achieve the miniature features, precision, surface quality, and yields required for manufacturing microfluidic devices for clinical lab-on-a-chip applications, precision drug-delivery catheters,...

Nonconventional machining technologies have been found viable to manufacture various products from a wide range of engineering materials. Wire electric discharge (WEDM), also known as Wire-EDM, is one the important thermal type nonconventional technologies. Wire-EDM being preferably used by manufacturers produce biomedical devices including bio and dental implants. This paper presents an overvi...

An analysis of electrical-discharge machined AISI D2 tool steel for high-cycle fatigue is conducted. The damage model was developed to reveal the in£uence of different electrical-discharge machining conditions on the fatigue life. The processed surface layer and the cross-section were examined by scanning electron microscopy (SEM).The experimental results show that the fatigue life of the EDMed...
