Ni alloys have managed to cover wide range of applications such as automotive industries, oil gas industries, and aerospace industries. However, these alloys impose challenges while using conventional machining technologies. On the other hand, Micro-Electro-Discharge machining (micro-EDM) is a nonconventional machining method that uses controlled sparks energy to remove material irrespective of...

Electrical Discharge Machine (EDM) is one of the non-traditional machining processes. EDM process is based on thermoelectric energy between the work and an electrode. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporization. The electrode and the work piece must have an electrical co...

Abstract The importance of geometrical accuracy can never be overruled in dies and molds which governs the dimensional precision parts being manufactured. continuous use such tooling requires repair maintenance. Among different processes used to upkeep consistency tooling, machining is essentially required most cases. intricacy molds’ cavities electric discharge (EDM). However, EDM it challengi...

The use of unconventional machining techniques in shaping metal matrix composites (MMCs) has generated considerable interest as the manufacturing of complicated die contours. Metal matrix composites are advanced materials having high specific strength, good wear resistance, and high thermal expansion coefficient. Electrical discharge machining is a best process to make complicated shapes on the...

The objective of this paper is to study the effect of the various process parameters i.e. peak current, noload voltage, pulse on time and duty cycle on response parameters by mixing silicon powder in the dielectric fluid of the Electric Discharge Machining (EDM). Response surface methodology (RSM) is used for investigating the effect on these parameters. Central composite design (CCD) is used f...

Electrical discharge machining process is one of the most Applicable methods in Non-traditional machining for Machining chip in Conduct electricity Piece that reaching to the Pieces that have good quality and high rate of machining chip is very important. Due to the rapid and widespread use of alloy DIN1.2080 in different industry such as Molding, lathe tools, reamer, broaching, cutting guillot...
