KEWL!!
So, did they make a real world widget(?), or are they showing off their AWESOME machining center?
Rog
My kind of porn video!
I wanna know how long it took to write that routine...
I always find CNC/milling to be somewhat mesmerizing. 
That is awesome, but all I keep thinking is how many ways I could hurt myself with it.
That's a marketing piece specifically designed to show off the capabilities of their machine, made from a steel alloy specifically selected and conditioned for ideal machinability, with a lot of time spent perfecting the programming in favor of maximizing material removal rate over tool life...And it all came together beautifully!
The tool path 
I had times I wanted to pull my hair out with the simple 2D CNC plasma table, I can't imagine that. That's ever so slightly more advanced than the Burny 2.8 though.
If I ever win the lottery (I'd have to play) or the ghost of Ed McMahon were to show up with a check for a gazillion dollars, this is the kind of stuff I'd blow it on.
Dang!
They'd be able to ramp up the speed 2 or 3X if the cooling fluid was turned on.
I wonder if I could fit one of those in my basement.
I'm done. 8)
Count me in that if I ever had the big bucks, I would have something like that in my personal shop.
Leno collects his cars. I would have a shop where I could build whatever the hell I wanted.
Site is blocked at work. From the sounds of it, very little "programming" with like actual code writing went into this. Computer generated tool paths FTW, just got to pick the correct cut type to get the computer to use the right algorithm and it pretty much does it itself.

Intuitively this would seem logical. But they're probably already pushing the feeds and speeds for those cutters in that material, yet are not having any problems with clearing chips or overheating the part. Only a few times did I notice sparks, or even discolored chips. Might be able to do it somewhat quicker, and with better tool life, with mist lubrication or flood coolant. But not by nearly as much as one might think. Many newer machines and cutters are being designed specifically with high-speed dry machining capabilities in mind.

Its pretty much this, with some tooling change orgasms thrown in.
All I see is some 22 year old CAD newbie standing beside me saying. "I did the hard part I drew it in solidworks, you just have to make it".

Probably turned off for the video, if it was turned on you couldn't see anything.
Im going to need a few minutes to my self. Please turn off the lights and shut the door on your way out.

That's when you count yourself lucky if the design is even possible to make.

Nah, it looks like some regular A36 to H13 or so.. It is totally a sample part, though, but it's a nice one..

Although they're definitely not programming by hand, I think it's a bit disingenuous to imply that there wasn't talent involved in programming that part :)

You don't want to run coolant with those materials.. Although the roughing toolpaths weren't as efficient as they could have been, the idea is that you're transferring all the heat of the cut into the chip, so when the chip breaks away it carries the heat with it. If you nail your RPM & feedrate, you should be able to machine that stuff and then touch the tool as soon as it's done.
Rule of thumb: Alloys: Always use coolant, Ferrous: Never use coolant, Stainless: flip a coin.
If you guys have any feeds & speeds or technique questions, I'm happy to talk about machining, it's my industry, and I do the multi-axis bits :)

Hah! I was about to make the same joke :)

They don't necessarily "teach" you everything in school, I was guilty. In another life, when I first started, one of the fabricators came to me with the pieces I'd drawn and cut for him, and the plan. "Uhhh, Lee, I get what you're wanting me to do here, but just how do you expect me to fit the end of a MIG gun in between there?"
I was mesmerized. It looks like it could be a pitch change mechanism for a propeller. Would love to have that in my garage.
All discussion of actual ability vs milling porn aside, it was excellent to watch. Very calming.
