Abstract Scope |
The timely fabrication of large, complex metallic structures is a persistent challenge for America’s industrial base. On-going work is addressing these challenges through the development of a large-scale hybrid metal manufacturing system which combines multi-material metal inert gas deposition, structured light-scanning metrology, part handling and five-axis machining. Existing challenges in the hybrid manufacturing of complex, multi-material part topographies will be discussed in the context of on-going research efforts. Deposition challenges include the monitoring and control of melt pools and layer deposits to improve the accuracy of printed preform geometries and to eliminate the presence of deposition defects. Metrology research is focused on generating accurate, but efficient, path plans for automated fringe projection scanning of part geometries. Finally, challenges with part residual stress and distortion will be discussed since they couple across deposition and machining and represent a fundamental barrier to final part accuracy and performance. |
