Investigation of Effect of Friction Stir Drilling Parameters on Elastoplastic Behaviour of Al Alloy

The aim of the research work was to investigate on the effect of drilling parameters on ultimate tensile strength of holed specimen. The specimen tested for study to determine the UTS for both conventionally drilled hole and frictional expanded hole. The thickness of the plate, taper drill angle, lubrication rate, feed and drill speed increase the pressure and temperature of the work piece is optimized using Taguchi technique. ANOVA shows feed rate, tool rotation speed and thicknesses of plate are the most influenced parameters.
