Study Of EDM Properties of Reinforced Cryogenic Treated Aluminum Alloy AA6063 Composites

Abstract

Materials are in high demand because of the constant force to enhance the functionality of structural, aeronautical, and automotive parts. Consequently, it motivates the discovery and manufacture of composite materials. Aluminum metal matrix composites employ in the automotive and aerospace industries due to their high strength-to-weight ratio and wide range of acceptable mechanical and tribological qualities. This study analyzed the surface sticks of AA6063-B₄C composites that cryogenically treatfor their ED machining capabilities. Stir casting is one of the liquid metrological methods employed to create B₄C particle-reinforced aluminum metal matrix composites—different soaking times in liquid nitrogen on the samples (13, 26 & 39 hours). Various inputs, such as soaking time (SoT), electrode gap (Gap), Current, Pon (Pulse ON time), and Poff (Pulse OFF time), were studied about the outputs of material removal (MR) rate, tool wear (TW) rate, and surface roughness (Ra). It observesby experiment that Current is one of the most influential parameters for ED machining.
