N2 - This paper presents a study on the relationship between feedrate and fatigue life of Al7075-T6 specimens before and after shotpeening. For this purpose, six groups of specimens, each of which consists of eight specimens, were first machined at six different feedrates (0.05, 0.10, 0.15, 0.20, 0.25, 0.30 mm/rev). Half of eight specimens in each group were then peened and the others remained un-peened. Next, the fatigue life was measured by using 4-point rotary bending machine. One observation was that the fast the feedrate was, the large the mean diameter of a specimen was. To apply the same bending stresses in all cases, different loading conditions were thus recalculated and applied to specimens based on their mean diameters. Finally, the effect of feedrate on the fatigue life was estimated by comparing twelve sets of specimens (six groups times two sets, peened and un-peened).
