Experimental investigation on machining parameters of Al6061-Mgo

Abstract

The objective of the current paper is, to investigate the machinability on Al 6061-Mgo metal matrix considering machinability parameters like speed, feed, depth of cut. Aluminum is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation. It is widely used for high performance applications such as automotive, military, electricity and aerospace industries because of their improved physical and mechanical properties such as light weight, high strength, good corrosion resistance, malleability, etc. Al metal matrix is the material. In the present work aluminium is used as the matrix and several reinforced materials are embedded into the matrix. Al 6061 aluminum alloy is reinforced with 1.0 weight percentage of Magnesium Oxide (MgO) particles through stir casting. In the present work, the influence of alloying elements in Al 6061 alloy have been investigated Casting of specimen having mentioned composition were prepared using stir casting method. Experiments were performed machining parameters like speed, feed, depth of cut during the turning operation with rake angle 15o per various trials, by changing the machinability parameters and calculated for all trials resultant force and frictional force with the help of merchant cycle and identified optimized machinability parameters.
