Abstract:
This study lies within the general scope of design and manufacturing processes improvements of aeronautical machined parts requiring fatigue behaviour guarantees. For the investigated aluminium alloy, the local stress intensity factor (Kt) has been identified as the characteristic parameter of the fatigue life. The proposed approach couples a model connecting the machining parameters with the generated surface and a fatigue model based on Kt determination by finite elements calculations. A maximum error of 15% in terms of fatigue life was obtained in the HSM milling cases studied.
