Effect of Cutting parameters, Point angle and reinforcement percentage on surface finish, in drilling of AL6061/Al2O3p MMC

Metal Matrix Composites (MMC) offer numerous thermo-mechanical advantages over standard materials and alloys which make them better candidates in different applications. Their light weight, high stiffness and strength have attracted several industries such as automotive, aerospace, and defense for their wide range of products. However, the wide spread application of Meal Matrix Composites is still a challenge for industry. The hard and abrasive nature of the reinforcement particles is responsible for rapid tool wear and high machining costs. An effort has been made to analyze the machining parameters and surface finish for cost effective solution. The important effects have been discussed and percentage contribution of various process parameters speed, feed, point angle on surface finish, force, torque and Cylindricity have been determined.
