| Abstract Scope |
Hybrid metal additive manufacturing (AM) was used to manufacture a Ti-6Al-4V component based on laser powder bed fusion (LPBF) and 3-axis milling. The component specifications could not be satisfied using conventional subtractive manufacturing. Hybrid manufacturing was employed to manufacture the nontrivial geometry with a high degree of accuracy and surface finish. Available manufacturing parameters were modified to accommodate the manufacturing conditions present within the build chamber that precluded the use of machining coolant. The machining steps were integrated every 6 to 12 additive layers. Component characterization was done using X-ray computed tomography, micro-hardness mapping, and surface roughness measurements to quantify the uniformity of the build with respect to build height. Ultimately, the complete component was manufactured multiple times sequentially without pauses or human intervention (i.e., lights-out). This analysis highlights the feasibility of hybrid manufacturing for Ti-6Al-4V components with complex geometry and provides a strong foundation for further research. |
