Aluminium metal matrix composite is widely used in wear resistance applications due to its weight and high strength. It is said to be a perfect composite and alternate material for our day-to-day used supplies. This work aims to study the machining performance of basalt fiber reinforced with aluminium (6082) metal matrix composite. The basalt fiber reinforced aluminium metal matrix was prepared using stir casting techniques with different weights of basalt fiber. Then, the fabricated metal matrix composite was subjected to machining studies using abrasive water jet machining by varying machining parameters such as stand-off distance, travel speed, pressure by measuring the surface roughness, hardness, and density. Furthermore, kerf angle was also measured to find out the optimum weight percentage of the basalt fiber to be reinforced to aluminum metal matrix composite; 2.5 wt % shows the better machining properties while comparing all weight percentages of basalt fiber. Vickers hardness test and density test were also carried out to show the fiber content to be used to reinforce it to the aluminium 6028.
