thermoelectric process in which heat energy of spark is used to remove material from the work piece. The machining process involves controlled erosion of electrically conducting material by the initiation of rapid and repetitive electrical spark discharges between the tool and workpiece separated by the dielectric medium. The present work is aimed at characterizing the electric discharge machin...

This study evaluated the cyclic fatigue resistance for six types of 25# NiTi instruments. A traditional manufacturing instrument, an M wire a gold treatment controlled memory (CM) CM instrument with electrical discharge machining (EDM), and R-phase heat were operated in different curved artificial canals. The fracture time (FT) number cycles to (NCF) instruments higher at 45° angles double-curv...

Stainless steel is a material which has high corrosive resistance and oxidation at temperature with the combination of chromium, nickel, niobium as primary constituent. This difficult to machine complex shape taken by using wire cut electric discharge machining. Wire electrical machining nontraditional process widely for cutting shapes. review paper involves EDM optimization parameters. Pulse i...

The surface layer machined after electrical discharge machining (EDM) is different from it traditional methods, and studying the structure by this method will contribute significantly to selection of finishing methods. In study, SKD61 steel EDM using copper (Cu) electrode was analyzed. Technological parameters including current (Ie), pulse on time (Ton), off (Tof), voltage (Ue) were used in stu...

This paper reports an intelligent approach for process modeling and optimization of electric discharge machining (EDM). Physics based process modeling using finite element method (FEM) has been integrated with the soft computing techniques like artificial neural networks (ANN) and genetic algorithm (GA) to improve prediction accuracy of the model with less dependency on the experimental data. A...
