Thermal-Stress Technique for Cutting Thin Glass Sheets

A technique based on the generation of highly localized thermal stresses has been devised as a means of cutting both flat and curved glass sheets of thicknesses between 30 and 600 µm. The technique is reliable, accurate, and economical. The technique can be used, for example, to cut thin glass sheets for microscope slides and for covers on laptop-computer displays and other flat-panel displays.
