For more than a decade, the authors’ companies have been advancing their respective visions for residual stress and machining distortion management in large, three-dimensional components.  During that time, substantial progress has been made towards solving a myriad of complex technical challenges.  Recently, under the Metals  Affordability Initiative, the Air Force provided opportunity for stakeholder companies to join forces in an integrated planning effort to outline a technology roadmap.  The process affirmed that more than ever, knowledge of residual stress influences on design/manufacturing processes is essential to both assure conservatism and maximize performance.  Furthermore, expanded supply chain integration is necessary to realize the full range of end-product benefits.  This presentation summarizes the ongoing effort to develop the roadmap and execute the vision.
