Abstract
The present disclosure describes a method comprising ablating a substrate with a laser at an orientation to create a cavity in the substrate, scanning the cavity, and creating a three-dimensional surface for the cavity. The method further includes storing the three-dimensional surface in a dataset. The dataset includes a laser projected distance as an independent variable and a depth of cut as a dependent variable. The method further includes fitting parameters of a gaussian-based model for the laser and the substrate based on the dataset. The present disclosure also describes a method providing a pre-ablation surface, labeling a three-dimensional obstacle boundary that separates material to be remove by a laser and material to remain, and determining an orientation of the laser that results in a predicted post-ablation surface that does not intersect the three-dimension obstacle boundary.
