AB The paper describes an experimental study developed on the AA7075 T651, which isan aluminum alloy extensively used in the aeronautical industry. This work presents a doubleapproach of investigation where there is no literature about previous research. This includes theanalysis of the results obtained by the combination of mechanical and chemical actions on themechanical properties of this material. On the one hand, the combinations of relevant millingparameters (feed rate, cutting speed) on flat samples (flat specimens have been selected by attemptingto reproduce with the most accurate way the geometry and the type of machining process known asface milling is usually used in this manufacturing field). On the other hand, the stimulating effectof the corrosion by salt spray on selected batches of specimens was machined in the previous stage.Results from tensile tests performed on the whole of specimens allowed us to evaluate how the mainmechanical properties (yield strength, tensile strength, and elongation at break) have been affectedby the processes applied. Elongation at the break presents a reduction in an inverse order to feeda rate increase (up to 24.5%) and this reduction is extended (additional 19.17%) in specimens undercorrosion conditions, which results in a greater fragility of the material.
