This paper investigates the influence of jet traverse speed and water jet pressure of abrasive water jet machining (AWJM) on the magnesium-based metal matrix nanocomposites (Mg-MMNC) reinforced with 50 nm (average particle size) 0.66 and 1.11 wt.% Al2O3.The extent of grooving caused by abrasive particle and irregularities in AWJ machined surface with respect to traverse speed and cutting depth was investigated. The nanoindentation results hows softening of the material defended by higher reinforcement content nanocomposite due to presence of sufficient amount of nanoparticles protecting the surface from being damaged. The values of selected amplitude parameters viz. average roughness (Ra), maximum height of peak (Rp), maximum depth of valleys (Rv) presenting the comparatively smooth surface finish in 1.11 wt.% reinforced composite at high (500 mm/min) speed. Moreover, the high water pressure AWJM produces the better surface quality due to sufficient material removal and proper cleaning of debris from the machining zone as compare to the low water pressure, low transverse speed and low abrasive mass flow rate.
