Machinability Studies on Sic Reinforced with Aluminium 6061 and 7075 Alloy

Abstract

Metal matrix composites are used mostly in aerospace, space ships, automotive, nuclear, biotechnology, electronic and sporting goods industries. Due to their high cost, experiments are usually done to reduce the cost of the composites and in expensive materials are utilized for metal matrix composites. The machinability of MMC is different from the traditional materials because of presence abrasive reinforcement particles. During turning operation, the cutting forces (Ft, Ff & Fr) have increased with increase in weight percentage of SiC. At constant feed rate and different cutting speed, the cutting forces are increases on increasing the depth of cut. That indicates the power consumption during machining of aluminium alloy MMCs will increases on increasing the depth of cut at the same condition.
