  16. 16. A400M - Channel Fitting Optimization - TBEMC22 - Ref. M53PR1109510 - Issue 1 November 2011Comparison between Milled and Casted Part • A significant weight reduction was not possible as fatigue allowables are 50% of the ones used for the milled part and a new sizing load case did come up late (milled part: 21,965Kg, casted part 21,786Kg). • A cost reduction of 43% has been achieved for each part. • Topology optimization in combination with flexible casting technology was the key for this success.Seite 16 © AIRBUS Operations GmbH.
