This article focuses on including into the topological optimization method, all the mechanical stresses applied during the part lifetime and especially during machining phase. Thus, in addition to the part technical specifications, we consider static and vibratory forces during machining, and also forces during mounting and unmounting in the machine tool and then in the aircraft. Results show that taking into account handling and machining forces, static and vibratory, strongly impact topological optimization, thus shapes and weight, and should be considered during the early stage of the design in order to optimize the additive manufactured parts costs.
