Overview

The characteristic width lookup table is used to find characteristic widths for different parameter combinations. This table is generated as part of the single bead tuning process and will be used to help determine heat source penetration depth and absorptivity for all thermal simulations. The table contains data points for characteristic width at different power and speed combinations.

Format

The characteristic width lookup table is in csv format with columns for speed (m/s), power (W), and characteristic width (m). Speeds and powers in the first two columns should span the range of possible inputs for those two parameters. The power-speed combinations should be organized such that there is a characteristic width value for each power at each speed, creating a rectilinear grid. An example of this file is provided as CharacterisiticWidthExample.csv.
