| Abstract Scope |
Wire Arc Directed Energy Deposition (Arc-DED) is being explored by aerospace manufacturers as an alternative to metal castings and forgings for the fabrication of large metal spare parts, as it does not require specialized tooling, reduces material waste, and significantly reduces production lead time. Its use also enables topology optimization (TO) in the redesign of conventionally manufactured components, which can further improve a part's structural efficiency and overall design-to-fly ratio. However, adapting TO results often requires design iteration to compensate for constraints inherent in the manufacturing process.
The extension of Arc-DED to workcells that feature a coordinated robotic arm and tilt/turn table provide more toolpathing flexibility, such as allowing for part reorientation to produce overhangs not traditionally possible in 3-axis systems. In this work, a TO aerospace component is used to explore how part geometry and toolpathing decisions are affected when adapting TO results to multi-axis vs. 3-axis Arc-DED. |
