Abrasive water jet machining is one of the most non-conventional methods for machining. It is widely used in fabrication industry to machine the materials like aluminum, mild steel, copper, glass, titanium, hard rock material, graphite, ceramics, composite material, etc. Abrasive Water Jet Machining (AWJM) of Titanium (Ti 6Al 4V) has commercial importance due to its decent machining characteristics. In the present paper an effort has been made to optimize machining factors employed in Abrasive Jet Machining of Ti 6Al 4V using Taguchi technique. The methodology used is established on the analysis of variance and Grey Relation Analysis (GRA) to optimize the AWJM process factors for effective Material Removal Rate (MRR) and Surface Roughness (SR). Significant AWJM machining parameters such as traverse speed, abrasive flow rate & stand-off Distance were expected for optimized MRR and SR. It was set that determined optimal combination of AWJM process factors satisfy the actual need for Ti 6Al 4V in actual run-through.
