The electrical discharge machining (EDM) process is mostly used in conditions that complex and intricate shapes need to be machined on very hard metals. However, the leaves behind some undesirable properties such as high surface roughness, rough topography, residual tensile stresses, micro-cracks, heat-affected zone (HAZ), recast layer. This paper investigates effects of different output parame...

Electric Discharge Machining is a non-conventional machining process, used to machining difficult to machine materials. The major problem faced while doing EDM is high tool wear rate, end wear, corner wear , surface roughness and low material removal rate,. In this research work experimental investigations have been made to find the machining characteristics of high density ultra fine graphite ...

The aim of this paper is to study the Electro discharge machining process. EDM has been an important manufacturing process for the tool, mould, and dies industries for several decades. The process is finding an increasing industrial use owing to its ability to produce geometrically complex shapes as well as its ability to machine hard materials that are extremely difficult using conventional pr...

In this paper, the cutting of Tungsten Carbide ceramic using electro-discharge machining (EDM) with a graphite electrode by using Taguchi methodology has been reported. The Taguchi method is used to formulate the experimental layout, to analyse the effect of each parameter on the machining characteristics, and to predict the optimal choice for each EDM parameter such as peak current, voltage, p...

Micro-plate implants are jaw in the form of straight plates. The need for micro-plate Indonesia is quite high. Current fabricated using two machining processes, namely Wire Electrical Discharge Machining (wire-EDM) and micro-milling. These processes one reasons why price market expensive. One way to lower shorten implant manufacturing process. This research develops a process EDM die-sinking ma...

In recent years, incessant research in material science has encouraged the engineering and development of advanced ceramic materials. Such materials satisfy the needs of high end applications in the areas of aerospace, automotive, defense, biological and nuclear fields. Whereas, due to inherent capability of machining of any conductive material irrespective of its hardness and strength, Electri...

Electric Discharge Machining (EDM) is one of the machining process, which is used to produce critical shape on any type of hard or brittle conductive material and it can also be well applied for materials that are impossible to machine with traditional machining processes. The present work mainly demonstrates the optimisation process of multiple responses i. e. MRR, TWR and OC of EDM by using g...
