Abstract The electrode is an essential tool in electrical discharge machining (EDM). quality and efficiency of EDM are directly determined by the performance materials. Copper tungsten alloy (CuW50) pure copper cuboid electrodes were fabricated wire-cut (WEDM). parameters processing current, pulse width selected as test variables, single-factor experiment was carried out on SKD61 die steel with...

Extremely hard materials can be easily machined by Electrical Discharge Machining process due to its thermal erosion nature. In this process, the amount of material removed is directly proportional to the discharge current. Due to the stochastic nature of the thermal erosion process, the discharge current is varied for every applied electrical pulse. It results in different levels of material r...

In the current research, neuro-fuzzy model and regression model was developed to predict Material Removal Rate in Electrical Discharge Machining process for AISI D2 tool steel with copper electrode. Extensive experiments were conducted with various levels of discharge current, pulse duration and duty cycle. The experimental data are split into two sets, one for training and the other for valida...

Advanced engineering ceramics which are widely used as high strength refractory material for several industrial applications, always pose a challenging opportunity to machine them. Conventional methods of machining are difficult to shape them because of their high hardness and brittleness, while grinding is the only popular method to machine them, but shaping of ceramics in desired form is diff...

whereas in electrical discharge machining (edm) the heat flux entering the workpiece is extremely high, the fourier heat conduction model may fails. this article reports on determination of temperature distribution in the workpiece due to edm using non-fourier heat conduction model. equations are solved by deriving the numerical solution. the temperature layers and profiles of sample calculatio...
