They're doing some amazing things with lasers these days. I recently had an interesting talk with one of our sheet metal vendors. He said they got a new laser metal cutting machine, apparently it uses fiber optics and solid state lasers. He said it performs very well. When you factor in traverse time and die change time (automatic die change on a turret) the laser machine is as fast as a punch press. I'll have to see if I can go see it in operation.
