Machine creates aluminum helmet - incredible

The concept is pretty simple: carve a block of aluminum into a shape. The execution, however, is nearly mesmerizing as the machine sends aluminum shavings flying with computerized precision.

There are quite a few steps skipped, however, and I would love to see the entire process in a single time-lapse video. I would also like to know how close to 100% recycling the manufacturers are with the cast-off aluminum shavings. I would hope pretty close.
