I use a waterjet cutter as part of the process of making my PhD work at the University of Sunderland. A waterjet is similar to a laser cutter, but uses high pressure waterjet and garnet grit to cut through glass or metal. The process involves creating a drawing in AutoCAD or Adobe Illustrator and then programming the machining of the cut. It is a complicated process, but allows you to cut glass with a level of detail and accuracy that was previously impossible!
This is the waterjet console at the University of Sunderland with a drawing of some test pieces ready to cut:
