Abstract

Abrasive Water Jet (A WJ) machining is one of the non-traditional machining methods popular for machining of hard, heat sensitive and brittle materials. The present work investigates the effect of feed rate, operating pressure and standoff distance (SOD)on surface roughness produced while machining of D2 steel. It is found that increase in operating pressure reduces the surface roughness. Other parameters such as SOD and feed rate (Percentage contribution 6.2 % and 6.4 % respectively) were found to be statistically insignificant within the ranges of experimental settings. Further,during the erosion of material, the abrasive loose its kinetic energy leading to formation of wear tracks and burrs as well as peaks and valley on the machined surface. At optimum levels of the processparameters the surface roughness obtained is 2.46 urn.
