    Abstract: The embodiments include a system, comprising: a scanhead with a marking laser having a marking field. The system includes a vision system having a camera embedded in the scanhead having a field of view (FOV) within the marking field and an autofocus module which uses pixel information in an in-focus region of interest (ROI) of a target surface of a part to obtain a Z-axis focus in a vertical dimension above a two-dimensional (2D) plane. The marking laser selectively marks with a laser beam the target surface in the marking field based on at least the Z-axis focus.

    Abstract: A method of removing a coating of a substrate comprises a series of steps. A substrate is provided, the substrate including a feature on a surface of the substrate. The surface of the feature has a coating. The surface of the substrate is imaged to provide information about the feature. A portion of the coating is removed by a laser source. The surface of the substrate is imaged to provide information about a coating thickness of the coating of the surface of the feature. A boundary is calculated between a first area including the coating and a second area with the coating substantially removed. A portion of the coating in the first area within the boundary is removed using a laser source.
