Acrylic is a very common material to cut on a CNC.  It can be used for anything from making windows in projects to making edge-lit LED signs.  Acrylic can be a tricky material to cut successfully, mainly because many people will run the RPM of the cutter too fast with a feed rate that is too slow, thus causing melting of the plastic.   The trick is to get nice clean chips as you cut.
