It's a long video, but absolutely worth watching. There's not a lot of detail about the software side of things, but it's fascinating to think about the number of things that have to be taken into account to take a shape from a 3D model, to a basic toolpath, to a toolpath that takes into account the elastic vs plastic deformation of the steel, the amount of force required at each point to get just into plastic deformation and no further, the deflection of the robot arms caused by that force, the deflection of the steel sheet, the variable thickness of the sheet caused by the order of forming operations... it's mindblowing. As the guy says at the end - even with our advanced computing technology, "...it's faster to form a part than to simulate it."
