Inherent and machining induced stresses can cause distortion in final aerostructures, with potentially costly consequences amounting to millions of US dollars. This innovative work has resulted in a process that minimises stress and distortion through the careful selection of material and machining strategies. To verify the conclusions, element deletion, finite element analysis, and additional machining were employed.
Distortion of aerostructures results in parts being reworked or scrapped. This is an unacceptable loss, both financially and environmentally.
