| Abstract Scope |
Selection of appropriate process parameters for directed energy deposition (DED) is critical to build success but presently requires a prohibitive quantity of time, capital, and experience. To reduce decision-making risk, a framework is proposed to support statistical optimization using an experimentally derived process model. The developed framework was demonstrated using nickel-aluminum-bronze (NAB) feedstock with the arc wire DED process pursuing application requirements of as-built surface condition and global productivity for thin-wall geometry. Quantitative analytical metrics were devised apply structured light metrology and thermal simulation for each trial condition to establish the process model. The obtained process model was used to select an optimized set of process parameters which enabled fabrication of a thin-wall component geometry in an optimized condition. The described framework is intended to be tailorable based on process, material, and application requirements through selection of process inputs, defined analytical criteria, and experimental geometry investigated. |
