Abrasive water jet machining process plays a crucial task to many manufacturing process, as it eliminates the heat generated in the machined part and formation of chip during machining were eliminated. It uses a mixture of abrasives and water as the medium for material removal action. It does not involve a cutting tool as the removal work is attained through the mechanism of eroding the work material. Moreover, formation of chips during the material removal will be in the order of micron level. The proper selection of process parameters is essential towards superior performance in the area of abrasive waterjet machining process. The research work experiments were carried by taguchi design further multi response optimization for machining on Inconel-825 was conducted through Grey relational analysis The performance characteristics considered are, the hole taperness and kerf angle. The optimization results also suggest that stand off distance abrasive flow rate, and traverse speed provide the most promising variables on reducing the hole taperness and kerf angle in Inconel-825.
