Abstract—-Aluminium alloys have been increasingly applied as a structural material in composite materials using metal matrix due to their excellent mechanical properties and low weight. Aluminium is among those metals which are difficult to be welded by normal fusion welding processes. Aluminum MMC was particularly selected as it possesses increased elevated temperature strength and wide range of extensive applications.  The excellent mechanical properties of these materials and relatively low production cost make them a very attractive candidate for a variety of applications both from scientific and technological viewpoints. Low melting point and high thermal conductivity are the two major factors contributing to this phenomenon. In our present work we have fabricated AA6061 composite material (in the shape of rod), an aluminium alloy, which is reinforced with Al2O3 in different quantities to improve machinability. Later we determined the cutting forces of each rod using lathe machine with dynamometer for better selection of rod. We found that the parameters like cutting speed, feed rate, depth of cut severely influences the cutting force. This analysis of cutting force provided better selection of tool for Friction Stir Welding.

Keywords—-metal matrix composites, friction stir welding, cutting force, dynamometer.


MMC (Metal matrix composites) are metals reinforced with other metal, ceramic or organic compounds. They are made by dispersing the reinforcements in the metal matrix. Reinforcements are usually done to improve the properties of the base metal like strength, stiffness, conductivity, etc. Aluminium and its alloys have attracted most attention as base metal in metal matrix composites. Aluminium MMCs are widely used in aircraft, aerospace, automobiles and various other fields. The reinforcements should be stable in the given working temperature and non-reactive too.
