Titanium is extensively utilized in aerospace and medical scenarios owing to its outstanding mechanical properties and corrosion resistance. Conventional machining of titanium alloys is challenging because of its innate characteristics like hardness, lofty reactivity, modest thermal conductivity and elastic modulus. Therefore, an attempt has been made to study the ease with which titanium alloy (Ti-6Al-4V) can be machined using abrasive jet machining (AJM). Machining of holes in Ti-6Al-4V was executed by incorporating a group of input parameters—air pressure, abrasive grit size and standoff distance. The output responses such as material removal rate (MRR), circularity, radial overcut (ROC) and taper angle (TA) are chosen for the evaluation of the experiment. The machining parameters are optimized for higher MRR (case 1) and for lower ROC and TA (case 2) using multi-objective grey relational analysis to choose a moderate course among the output parameters.
