The Electric Discharge (EDM) method is a novel thermoelectric manufacturing technique in which materials are removed by controlled spark erosion process between two electrodes immersed dielectric medium. Because of the difficulties EDM, determining optimum cutting parameters to improve performance extremely tough. As result, optimizing operating critical processing step, particularly for non-tr...

Abstract Electrical discharge machining (EDM) is one of the most widely used non-conventional methods to machine electrically conductive materials in manufacturing industry because its strong capability difficult-to-cut irrespective their strength and hardness. drilling (EDD) an important variant EDM. Due limitation conventional processes, special holes, particular those with high aspect ratios...

Corner accuracy occurring in wire electrical discharge machining (WEDM) is influenced by parameters such as vibration, lag, and excessive discharge, etc. This study proposed an optimization method which can improve the corner of WEDM process. The pulse-on time (ON), pulse-off (OFF), open circuit voltage (OV), servo (SV), tension (WT), flushing pressure (WA) were selected to investigate influenc...

A methodology is proposed to jointly model treatments with quantitative levels measured throughout time by combining the response surface and growth curve techniques. The model parameters, which measure the effect throughout time of the factors related to the second-order response surface model, are estimated. These estimates are made through a suitable transformation that allows to express the...

Optimization of operating parameters is an important step in machining, particularly for operating unconventional machining procedure like Wirecut Electro Discharge Machining. Since wire-cut EDM has experienced explosive growth in application users demand and need maximum productivity and through-put, increased accuracy, and predictable performance. Also machines and job requirements vary great...
