Abstract Scope |
Hybrid manufacturing systems combining directed energy deposition and subtractive capabilities in the same machine envelope were initially debuted in 2014. However, these systems have seen little industrial adoption. Given that most additive parts are preforms with required conventional post-processing to make them functional, it seems like hybrid systems would offer significant advantages. While more capable, the science of interleaving AM and conventional machining operations is complex. Fundamental understanding of factors like residual stress, microstructural evolution, and geometric distortion in these complex processes remains the primary barrier to success. This presentation details how research into the fundamental thermophysical properties of hybrid processes is being translated to real-world applications. Covering specific developments like a wire-arc hybrid machine installed in ORNL's Spallation Neutron Source and the development of the world's largest metal-wire laser DED hybrid system, the audience will gain an appreciation of the challenges and future opportunities for hybrid AM systems. |
