Impact of Processing Variables on Formability of AA7079 Sheet by SPIF Technique
The present work aims to study the formability of AA7079 alloy to fabricate circular frustum cones using the SPIF technique. Experiments were conducted as per L9 orthogonal arrays, and the Taguchi technique was used to examine the effect of input parameters on the fabricated component. A three-dimensional non-contact scanner was used to find the depth of the fabricated circular cone. The major factors affecting formability in order of significance are side wall angle, step size, spindle speed, and forming tool radius. Scanning electron microscopy was used to study the fracture surfaces, whereas energy-dispersive X-ray spectroscopy (EDX) was used to analyze the chemical composition of the base metals and the fractured areas over the frustum cone surface. The analysis shows that the best values for maximum depth were obtained at a wall angle of 55 degrees, tool diameter of 13 mm, step size of 0.5 mm, and rotary speed of 600 rpm.
