Abstract In the current scenario, manufacturing industries faces difficulties during machining of engineering materials-metal based, having higher mechanical properties viz. strength, toughness and hardness through conventional methods. These problems include rapid tool wear, poor surface quality work piece material lower stock removal rate. EDM is a single prominent what more lucrative unconve...

In this paper, it is shown that dynamic optimization problems of first-order systems can be transformed into a static parametric programming problem, where the state plays the role of the parameter. Thus, an optimal feedback law is obtained. This concept is applied to the diesinking Electrical Discharge Machining, a highly time varying industrial process which necessitates adaptation of machini...

Electrical Discharge Machining (EDM) process is one of the most widely used methods for machining. This method is used to form parts that conduct electricity. This method of machining has used for hard materials and therefore selects the correct values of parameters which are so effective on the quality machining of parts. Reaching to optimum condition of the DIN1.2080 alloy (D3) machining is v...

Preliminary notes This paper presents the possibilities of applying a new method of programming based on STEP-NC standards, which was developed as an alternative to the G code. The possibilities of application in the field of machining simulation and verification of the program before machining on the wire electrical discharge machine are discussed. The paper shows the possible methodology for ...

WEDM is one of the important variants of electrical discharge machining (EDM) which uses the thermal energy generated between the electrodes for machining the electrically conducive materials. This method has been successfully implemented in common materials like aluminum, stainless steel etc., But its application in super alloys like Ti6Al4V is still under investigations. This paper reviews th...

Electroconductive, homogeneous and dense ceramic/semiconductor/metal nanocomposites were obtained by hot press and subsequently machined by wire Electrical Discharge Machining (EDM). The addition of semiconductor and metal phases to a highperformance ceramic material produces nanocomposites which preserve the excellent mechanical properties of the ceramic/metal material while reaching the elect...

This study investigates the dry and near-dry electrical discharge machining (EDM) milling to achieve a high material removal rate (MRR) and fine surface finish for roughing and finishing operations, respectively. Dry EDM uses gas and near-dry EDM applies a liquid-gas mixture as the dielectric medium. Experimental studies leading to the selection of oxygen gas and copper electrode for high MRR d...
