| Popis: | The importance of synthesizing particles reinforced metal matrix composites is increasing owing to their distinct physical properties. The machining of such composites is a tedious process due to its higher strength. In the present study, an endeavor has been made to investigate the influence of process parameters in abrasive water jet machining process while machining TiB2 particles reinforced Al7075 composite. Water jet pressure, transverse speed and standoff distance have been considered as input parameters to evaluate the performance measures such as material removal rate, surface roughness and taper angle in the machining process using Taguchi-DEAR methodology. From the experimental investigation, it has been found that water jet pressure has higher influence on determining performance measures in AWJM process owing to its importance on determining impact energy. The optimal process parameters combination has been found as water jet pressure (280 MPa), transverse speed (345 mm/min) and standoff distance (4 mm) among the chosen process variables and evaluated using confirmation test with 1.2% of deviation from mean MRPI value. |
