…scribing the surface of the glass with a hard, sharp tool (typically a diamond or carbide wheel), followed by a mechanical snapping force such as a "chopper bar." The well-known drawbacks include microcracking and chipping of the edges, as well as debris formation, which all require post-processing…

…mechanical stress to propagate the crack completely through the glass. In automated systems, this separation is usually implemented by using a "chopper bar" that descends on the glass. This method has certain drawbacks, particularly for the aforementioned very thin substrates that are increasingly…
