Abrasive Water Suspension Jet (AWSJ) is one of the emerging non-traditional machining tools used in machining of brittle, heat sensitive materials and composites. Usually machining is carried out by the AWS jet in the air. Presence of air around the jet may lead to jet expansion which results in increased kerf width. In the present research work an attempt has been made to investigate the effect of various process parameters on kerf width using AWSJ submerged in water while machining of Glass Fiber Reinforced Plastic (GFRP) composite material. The experimental results indicate that the top kerf width decreases by 3% during under water machining as compared to that of free air machining.
