Abstract
Abrasive water jet
machining (AWJM) process is one of the unconventional machining processes used
in many industrial applications. Abrasive water jet machining process withstand
very high operating pressures and also the flow of abrasive particles are at very
high water pressure is made to remove material from work surface by erosion
process. In AWJM process pure water and abrasive particles such are Si02, beads of glass;
aluminum oxide and silicon carbide are majorly used. In this work, optimization
of process parameters on the material removal rate, kerf width and surface
roughness of Al6082 are done by using AWJ machining process. The experiments
were conducted according to Taguchi Experimental design using four factors each
at three levels to determine the effect of output responses like material
removal rate, surface roughness and kerf width. Finally, multi-criteria
optimization and compromise solution (VIKOR) algorithm has been applied for
multi-objective optimization of the responses of Electrical Discharge Machining
(EDM) process on Al6082 alloy.
