An Effect of EDM on AL6061-5% SiC as stir cast MMC

Abstract

Usage of advanced machining method in the formation of composites made of aluminum metal matrix (Al-MMC) has produced substantial ability because the manufacture of intricate die shapes in these tough material is of elevated precision and surface finish Impossible. EDM has proven to be one of the many unorthodox processing techniques that are successful in shaping These materials which are difficult to process. The main aim of this investigation work is to find the outcome of Pulse ON-time (Pon), Current (Cu)and flushing pressure (Fp) on tool wear rate (TWR), metal removal rate (MRR) taper (T), radial overcut (ROC), and surface roughness (SR) on machining Al6061 with 5% SiC reinforcement.[1,2] On this Investigation we are deputed Electronica PSR 35 and dielectric fluid was used as kerosene with the help of flushing machine to pump out the dielectric fluid. Copper is used as the electrode and it also used as a tool of diameter 3mm to pierce the work piece for the required length. Three machining parameter at each having three stages was used to perform the experiment on the orthogonal array of L27 taken into account. The experiments are conducted for three following trails in random order. The maximizing taken into account for optimization and ANOVA statistical tool is used and to find out the surface morphology SEM is taken on different parts of the work piece.[3]
