Abstract
Abrasive water jet machining process is one among the non- conventional machining processes and extensively used to drilling fired furnace and welded construction of bridges . An attempt is made in this project to measure the material removal rate (MRR) and surface roughness of stainless steel 316 and mild steel A36. Abrasive water jet machining is very promising in processing hard-to-machine materials and machining of stainless steel 316 and mild steel A36 using abrasive water jet machining needs attention. This paper focuses on establishing hole characteristics in abrasive water jet drilling using multi-objective grey analysis. The form and orientation characteristics of the hole are defined using entry and exit hole overcut, entry and exit hole circularity, and depth and surface roughness. The process parameters are water jet pressure, standoff distance, and abrasive mass flow rate. Analysis of variance of the individual responses is used to identify the pattern in which each parameter affects the performance of the process.
