Abstract Scope |
With the expansion of Wire-Arc DED, optimization of the deposition process is crucial for efficiency. Optimal stepover distance and printing strategy is instrumental to producing a successful build, yet existing methods use low-flexibility models or rely on human experience, resulting in costly and inefficient trial-and-error methods. This project develops an artificial intelligence to identify the optimal stepover distance from input process variables like wire feed speed and travel speed. Using non-linear regression models on experimental data of overlapping bead depositions, hundreds of synthetic data points are simulated to train a neural network. The network then identifies the best stepover distance by optimizing multiple output variables, like height difference between beads and the area of the valley of the deposition. Additional parameters, like waveform and deposition area, are also incorporated, creating a versatile tool tailored to specific applications. A graphical user interface further enhances usability for efficient DED programming. |
