Abstract
A system for detecting penetration through a blank by the beam of a laser cutter prior to cutting a workpiece from a blank. The laser cutting includes a frame defining an interior area bounded by first and second side walls, first and second end walls and a bottom. Means are provided for supporting the blank within the confines of the side walls and end walls and above the bottom. A gantry structure extends transversely of the frame and movable longitudinally thereof. A laser head is connected to and is movable longitudinally of the gantry. A main control for the laser cutter causes the beam to be reflected through the gantry structure and the laser head toward the blank. The system comprises at least one sensor module mounted on the frame beneath the support means. The sensor module is operatively connected to the main control such that the laser cutter begins cutting the blank upon detection of the penetration by the sensor module.
