An Analysis of the Influence of Cutting Parameters on the Turning Process on the Fatigue Life of Aluminum Alloy UNS A92024-T351

Generally, metal structural elements of aircraft are placed in zones of critical load; in most cases, these elements are manufactured by machining processes. The fatigue life of these components is an important dynamic property that may be strongly affected by the surface condition produced during machining. In this paper a preliminary study of the influence of cutting parameters on fatigue strength of parts machined in aeronautical aluminum alloy UNS A92024-T351 has been carried out. Special attention has been provided to the relationship with surface finish evaluated through the roughness average.
