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...

Abstract In wire electrical discharge machining (WEDM), the erosion is made through a series of overlapped craters. The shape these craters has relevant impact on characteristics machined surface, from surface roughness to heat effects during spark. Current models EDM process do not represent specific WEDM characteristics, such as radial asymmetry crater or geometrical shape. order characterize...
