Abstract In-envelope hybrid manufacturing systems comprised of directed energy deposition (DED) and machining provide flexibility for the fabrication complex geometries with minimal setup changes. However, these set ups, effects parameters such as laser power scanning speed on quality build remain relatively unexplored. An important aspect developing components reliable mechanical properties is a thorough understanding DED thermodynamics during fabrication. Therefore, were defined based...
Potential for a rapid hybrid additive/subtractive manufacturing technique capable of generating large aluminum components with deep geometrical features exists if, example, layers plates can be deposited and held in place using friction stir welding followed by machining. However, when are spot welded together, adjacent material deform causing gap between layers. This research investigates how tool geometry affects the formation interlayer gaps lap shear strength weld. For this purpose,...
