145330 - Enhancing the Performance Measures of Abrasive Water Jet Machining on Cutting Titanium Alloy Specimens 

The Titanium alloy specimens are widely utilized in many bio medical application industries due its higher corrosion resistance and lower density. Since the Abrasive water jet machining (AWJM) process is used to cut such materials, it is essential to enhance the process mechanism as much as possible. The optimization of the AWJM process can effectively enhance the quality measures. In the present study, an attempt was made to improve the performance measures of AWJM process with 40 mesh garnet particles while machining titanium (Ti-6Al-4V) specimens. The effect of input parameters such standoff distance, gas pressure, abrasive flow rate and feed rate have been evaluated on performance measures such as material removal rate, kerf width surface roughness using Taguchi TOPSIS optimization approach.  It was observed that the proposed approach could efficiently improve the quality measures. It was also observed that the abrasive flow rate possesses higher influential character on determining quality measures owing to its ability on modifying the impact energy.
