A manufacturing process is provided that includes steps of: providing a panel comprising a core connected to a first skin, wherein the panel is configured with a plurality of cavities extending through the core to the first skin; partially forming a first perforation in the first skin using a laser beam; operating a sensor to sense optical emissions produced during the partial forming of the first perforation; and determining, based on an output of the sensor, whether to: continue formation of the first perforation in the first skin; or terminate formation of the first perforation in the first skin.
