A Review Paper Submitted By Shaumilkumar Patel (50204321) On Abrasive Water Jet Machining In The partial fulfillment of Coursework IE 506 ABSTRACT Abrasive Water Jet Machining (AWJM) is a new machining technique. Abrasive Water Jet Machining is widely used in many industries, including mining and aerospace, for cutting, shaping, and reaming. AWJM is the extended version of Water Jet Machining. AWJM is a non-conventional machining process where the material is removed by impact erosion of the high velocity, high pressure of water and entrained high velocity of fine grit abrasives such as sand (SiO2) or beads of glass on a work piece. The Important process parameters which mainly affect the quality of cutting are hydraulic pressure, traverse speed, standoff distance, abrasive flow rate and types of abrasive material used in the process. The Important quality parameters in AWJM are Material Removal Rate (MRR), Surface Roughness (SR), kerf width and tapering of the kerf. This paper reviews the research work carried out so far in the area AWJM. Keywords: AWJM, Material Removal Rate, Surface Roughness, traverse speed, Kerf width INTRODUCTION Abrasive Water Jet Machining is a non-conventional process. AWJM works on principles of abrasive jet machining and water jet machining. In AWJM, material is removed by impact erosion of high pressure and high velocity of water and entrained high velocity of grit abrasives on work piece. Fig-1- different AWJM patent drawings and
