Watch This CNC Milling Machine Make a Bike Helmet
It might not seem like the best way to make a bike helmet, or even a practical one, but just watching this milling machine produce one is pretty cool. The device is a computer numerical control (CNC) Mazak Variaxis 5-axis machine, which replicated a Rudy Project Windmax helmet out of a block of aluminium. PowerMILL software was used to control the process. Great stuff.
