| Abstract Scope |
The timely fabrication of large, complex metallic structures is a persistent challenge for America’s industrial base. Delivery schedules for large parts, i.e one to two feet cube and larger, are routinely defined in months and years; introducing unacceptable risk and cost for most products. 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 (MIG) deposition, structured light-scanning metrology, part handling and five-axis machining. The resulting deposition-metrology-machining process cycle introduces design opportunities for complex, multi-material part topographies. The integration, capabilities and challenges of the system will be demonstrated through the processing of mild steel and nickel-aluminum-bronze structures. Progress in control of each process and overall integration will be presented, and the coupling influences across them highlighted. Potential implications and needs for future part quality and certification / qualification will also be discussed. |
