In recent years, aluminum metal matrix composites (Al-MMC) are found as a potential material for numerous applications owing to its excellent tribological and mechanical properties. In this work, the machining characteristics of aluminum alloy (Al7075) reinforced with TiC/MoS2 having nanoparticle has been studied. The samples of aluminum metal matrix composites by varying TiC in 0, 2 and 4 and MoS2 in 0 and 2 of the percentage weight of aluminum alloy (Composite 1(Al7075), Composite 2 (Al7075/2TiC/2MoS2) and composite 3 (Al7075/4TiC/2MoS2), respectively) are fabricated by the stir-casing method. The turning characteristics of the developed metal matrix composites are studied at various parameters such as cutting velocity (30 m/min, 60 m/min and 90 m/min), cutting depth (0.5 mm, 1.0 mm and 1.5 mm) and composites (1, 2 and 3) using TiN coated cutting tool by dry turning at 0.05 mm/rev feed rate. The turning characteristics of the prepared samples are compared each other under L20 orthogonal array on CNC turning machine. The significant findings in the present study are: hardness of base aluminum alloy is found to increase with the addition of TiC/MoS2 in Al7075; surface roughness and flank wear are found to grow with the addition of nanoparticles of TiC/MoS2 in Al7075, evidence of built-up edge is observed for addition of nanoparticles in Al7075; cracks are originated from the edges of the chip and are propagated to the inner side along shear planes on examining the chip shape..
