finished glass 600x450 CNC Milling Plate Glass and Mirrors

Ben Krasnow—of DIY electron microscope fame, among other impressive projects—has posted some useful notes on an unusual cutting process. Normally, of course, the recommended practice for cutting plate glass is scoring and breaking, but it can be cut using a more-or-less conventional milling setup provided you get the details right: an unfluted diamond cutter, proper tooling fluid, careful workholding, and a very, very slow feed rate. Ben covers all the tricks in this new video and this older post.
