Abstract

This paper presents a study on the effect of feedrate changes on the fatigue life of Al 7075-T6 specimens before and after shotpeening. For this purpose. five groups of specimens, each of which consists of eight specimens, were first machined at five different feedrates (0.05, 0.10, 0.15, 0.20 0.25 mm/rev). Half of eight specimens in each group were then peened and the others remained un-peened Finally, the fatigue life of each specimen was measured by using 4-point rotatry bending machine. Comparison of fatigue life among ten sets of specimens is presented.
