Ni alloys have managed to cover wide range of applications such as automotive industries, oil gas industries, and aerospace industries. However, these alloys impose challenges while using conventional machining technologies. On the other hand, Micro-Electro-Discharge machining (micro-EDM) is a nonconventional machining method that uses controlled sparks energy to remove material irrespective of...
The use of unconventional machining techniques in shaping metal matrix composites (MMCs) has generated considerable interest as the manufacturing of complicated die contours. Metal matrix composites are advanced materials having high specific strength, good wear resistance, and high thermal expansion coefficient. Electrical discharge machining is a best process to make complicated shapes on the...
In the present paper Artificial Neural Networks (ANNs) models are proposed for the prediction of surface roughness in Electrical Discharge Machining (EDM). For this purpose two well-known programs, namely Matlab with associated toolboxes, as well as Netlab , were employed. Training of the models was performed with data from an extensive series of EDM experiments on steel grades; the proposed mo...
The purpose of this paper is to optimize the EDM parameters to get the better surface finish on the Titanium alloys Ti6AL4V. The continuous advancement of the alloy is fulfilling the demand of the industry but for advance material like Titanium alloys Ti6AL4V partially adopted by industries cause of the difficulties in machining. Non Conventional machining process like Spark Erosion Electrical ...

Parameters Optimization of Electrical Discharge Machining Process Using Swarm Intelligence: A Review
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...
