Abstract [en]

In this work, a forming procedure for a geometry of interest to the aero engine industry was studied and proposed. The development work was performed according to the principle “first time right” in which careful material model calibration and FE-analyses of the anisotropic superalloy 718 and the FlexformTM procedure resulted in high correlation between predicted and measured responses. The influence from different process parameters such as friction coefficient, material property variations and blank design to the material thinning, spring back behavior and shape accuracy was investigated thorough a parameter study. By forming a suitable geometry from the metal sheet and subsequently machine to the desired component shape, the work was able to demonstrate the sustainability potential. A simplified life cycle analysis indicates that a decrease in energy consumption of 50% was reached, compared to the production method currently applied.
