Abstract: Due to the various superior and unique properties in aluminium metal matrix composites (Al + Si + Mg + Cu + SiC) on alloys; those are used in variety of industrial uses. The present paper studies the machinability aspects of turning and surface roughness in sintered aluminium metal matrix composites produced by powder metallurgy process and the various experiments were carried out by a CNC lathe with using tool inserts of titanium nitride coated tungsten carbide tool. This study attempts to measure and examine the influences of the depth of cut, feed-rate and cutting speed on surface roughness during machining of the composites. The cutting parameters and tool wear was influenced on the surface roughness. It was systematically analysed and a predictive model was established with-respect-to turning variables using Taguchi and response-surface methodology. The results showed that feed and cutting speeds are important, controlled, and dominant factors in the AMMC turning operation, considering the minimisation of machined surface roughness and the weight share of SiC reinforcement.
