Abstract Scope |
Wire-feed direct energy deposition (WFDED) is an up-and-coming AM method because of its high deposition rates and flexible application. However, the melt pool size in WFDED is hard to predict because the operating parameters are not independent. To better dimension control and predict the microstructure of as-built part, it is crucial to find a way to predict the melt pool dimensions in WFDED. In this work, we analyzed Ti-6Al-4V single-bead samples made with various power levels and speeds. Random forest (RF) method is used to develop a model to predict the melt pool size in WFDED and two other analytical methods are used to compare with our RF method in this research. An exhaustive dataset was used to train our RF model and the operating parameters affecting melt pool size most significantly are found. The analysis provides insights into the scope of data analytics methods for quantifying process uncertainty. |
