Progressive milling technologies, surface quality and fatigue properties of the aluminum alloy 7475-T7351

Original language description

The paper expands the knowledge of key cutting parameters of shoulder and face milling on the surface structure and fatigue properties of high strength alumina alloy 7475-T7351. The modern whole carbide cutters with advanced PVD coatings and progressive milling technologies (high speed and high feed cutting) at a five-axis machining center have been analyzed respecting the chip formation, force loading, specific cutting energies, advanced surface parameters, tool wear 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 G5 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 preliminary results confirm the high feed milling as a challenging technology with a good resistance to the formation of built-up-edge, acceptable surface quality, operation times and convenient fatigue characteristics of the machined material, but a new observation for the machining and its impact has been observed.
