A Study of Progressive Milling Technology on Surface Topography and Fatigue Properties of the High Strength Aluminum Alloy 7475-T7351

Original language description

The paper investigates the effect of key cutting parameters of shoulder milling on the surface structure and fatigue properties of high strength aluminum alloy 7475-T7351. The very advanced milling whole carbide cutter and progressive milling process conditions have been analyzed in the respect of force loading, specific cutting energies, the volumetric surface parameters and fatigue life of thin-walled components used for the dynamically loaded primary aerospace structures. The evaluation of the surface structure of the machined samples prior the fatigue testing and morphologies of the fracture surfaces afterwards was done using the modern optical high-resolution 3D surface microscope ALICONA-IF G4 and Tescan Mira 3GM scanning electron microscope. Cyclic fatigue testing for three loading levels was performed using the axial BISS testing machine with an advanced control of the testing. The results confirmed a statistically significant influence of cutting conditions on the surface structure, however, the material inclusions dispersed in the adherent machined surfaces seems to be the most decisive factor affecting the material integrity that triggers the fatigue crack initiations and propagations. Some unique studies like tensile tests in situ in scanning electron microscopy have been also made.
