| Abstract Scope |
Hybrid integration of Laser-Powder Bed Fusion (L-PBF) with Rotational Friction Welding (RFW) enables the manufacturing of complex assemblies, utilizing the full potential of Additive Manufacturing (AM). However, RFW is conventionally restricted to cylindrical geometries due to strict coaxial alignment and chuck-clamping requirements, resulting in a limited application. The proposed study presents a semi-automated parametric workflow for generating custom holding structures that allow non-standard geometries to undergo RFW. Implemented in a graphical programming environment using implicit modelling, the workflow analyses input geometry and generates a structure. To take full advantage of AM capabilities, the structure incorporates an internally graded lattice, reducing material usage, manufacturing time, and thermal artifacts associated with large solid L-PBF builds. The workflow was validated by generating a holding structure, successfully RFW a non-circular geometry and evaluating the joint with material testing and microstructure analysis. This work demonstrates a scalable path toward hybrid AM-RFW fabrication of complex components. |
