Abstract:
Methods and apparatus provide for supporting a source glass sheet and defining an at least partially non-straight cutting line that establishes a closed pattern that circumscribes a desired final shape; scoring the glass sheet at an initiation line using a mechanical scoring device; applying a laser beam to the glass sheet starting at the initiation line and continuously moving the laser beam relative to the glass sheet along the cutting line to elevate a temperature of the glass sheet at the cutting line to a substantially consistent temperature, where the laser beam is of a circular shape; and applying a cooling fluid simultaneously with the application of the laser beam, such that the cooling fluid at least reduces the temperature of the glass sheet in order to propagate a fracture in the glass sheet along the cutting line.
