Variable bead geometries using directed energy deposition process
Abstract: Process planning for multi-axis Directed Energy Deposition (DED) is an active area of research with many approaches being investigated. One such approach involves creating continuously varying deposition geometry by controlling the height and width of the deposited beads. This enables non-uniform slicing as a generalizable technique to deposit curved layers. This work investigates controlling both bead height and width by simultaneously changing the scanning speed and laser power. Regression models were developed to predict bead width and height as a function of scanning/traverse speed and laser power. These models were then applied to deposit beads in which both the height and width are controlled along their length.
