<br/><br/> In this study, the mechanical and the machinability properties of aluminum-silicon nanocomposites are studied. A356 alloy / 2% wt. nanoparticles stir cast samples are poured in different temperatures. Tensile strength, hardness, microstructure, and scanning electron are examined, then the turning process is performed to measure the cutting forces and arithmetical mean value (Ra). The strength and hardness increase because the particles dispersion. The forces and Ra increase with feed and cutting depth. Ra decreases with increasing cutting speed. The nanoparticles increase the cutting forces but produces smoother surface. Statistical analysis used to study the factors and the responses
