If this was a crankshaft for an actual vehicle the oil would flow through it to lubricate the bearings.

A forged crankshaft still requires machining after forging. The forged version may also be stronger, so "almost as good as a billet crank" is not always true. Machining from solid is the only way to go for prototyping. In fact, the added cost of materials and machining time for one-off parts pales in comparison the cost of the rest of the project (design and testing).

I was very impressed: speed of 2,000rpm. And I thought 1,000rpm was fast on industrial mill.

To redneck,,this is not how most cranks are made,way too expensive. I think it's just to show what this magic machine can do,,most cranks in your everyday ride have much cheaper forged cranks,,not really dadly made or anything,,just way cheaper,,and almost as good as a billet crank as you see it on here. Here's a one that will shock you though,,,look up how ball bearing balls are made,,you wont believe it man,heheh.

How long would it take to set up and program the sequence to make this? I would imagine that the machine would have no idea how to make this if a CAD drawing was thrown at it.

nice video
