In this video, a waterjet nozzle is raised a few inches above the work surface, and fired for a few seconds into the air. If you have never seen a waterjet, well, this is what it looks like. Keep in mind that there is about 30 horsepower going through that little stream of water! (no audio)
This video is slightly more interesting than the previous one. Here, a large mouse-pad, that is designed to wrap around a keyboard, is being cut from foam. The reason I chose to film foam being cut is because it is fast enough that the video can be worth watching, and you can see a complete part from start to finish. I also used an abrasive nozzle, which was really unnecessary. I could have used a water-only nozzle which would have made a nicer edge finish, but I did not have one handy. Also, because this was foam, I could have cut it much faster, but I chose a slower speed so that I could have time to react, should it want to float away on me or something.

This video shows cutting a pair of mating parts using a tilting cutting head that automatically removes taper from the part. This is probably the most interesting video to watch because of all of the tilting motions.

This video was taken at the Westec trade show a few years back (1997 or so). The video shows cutting from various angles, with narration.
Unfortunately, this one no longer can be streamed from the Internet, but you can order it on VHS through the University of Washington . Ask for "Seminars on Advances in Manufacturing and Management - ME 518", which was broadcast Monday, November 1, 1999 at 3:30pm.
