Abstract Scope |
Hybrid Manufacturing integrates metal additive manufacturing with machining to fabricate dimensionally accurate components, particularly excelling in near-net-shape manufacturing. However, manufacturing thin and complex structures remains a challenge under tight dimensional tolerances. The lack of surrounding stock material from the deposition phase introduces less rigidity during the milling process, resulting in an increased susceptibility to vibrations and chatter. To mitigate these issues, the implementation of optimized sacrificial structures is proposed. This approach relies on accurate data concerning the deflections of both the tool and the workpiece, influenced by the geometry of the milling tool and the mechanical properties of the deposited material. Thus, current work directions include: (1) utilizing a mechanistic force model to predict interactions between the milling tool and the deposited workpiece, and (2) incorporating these predictions into a Finite Element model in Abaqus to simulate and forecast milling-induced deflections. |
