What's the price tag on one of those things? A few $100k?
After buying it, having it setup, properly leveled, proven out, and purchasing all the tooling, you're looking at closer to a million.

Tool changes and position changes obviously weren't in the video. Actual cut time, yea, there is a way.

There's no way they ran a part that complex in 7 mins.
Yeah, there's no way it was ran in 7 minutes. Just the roughing out, would take well more than 7 minutes. Not to mention all the milling & boring being completed.

The video was clearly edited and skipped forward a bunch of times...you could see it pretty clearly.
Yeah, at 27 seconds in they cut several minutes of whittling out of there.

That's a million dollar machine and that process would take many hours

Also a mill FWIW
I didn't watch it to the end. That is some fancy equipment either way. Some high $$ stuff. The ones we had were Haas and a crappy Kitamura.

You obviously haven't been around CNC's very much.

We have several CNC's here at my work and they're awesome to watch. Always impressive if I'm taking a client through the shop and they're working on some big pieces.

Yeah, that part took the better part of a day to make. They only showed short clips of 2 or 3 tool changes, while each change probably took 10 seconds to a minute (I haven't actually seen one of these in action), and there were several dozen tool changes. All told the machine probably spent the better part of an hour just changing tools while working on that part. Not to mention the video cuts out all of the repetitive cuts, of which there were many.

I've seen parts that use 3 tools and have 1/1000th of the programming of that thing take 7 mins to run. And that's just lathe functions, no milling.

Is it typical for these machines to use no coolant, or did they run it dry just for the video?

I found that strange. I always thought they used juice to cool it off and lubricate.

I found that odd as well. I've never seen a CNC late or mill that didn't use coolant. It may have something to do with how many RPM's they're running. Lower RPM's may not require coolant. Although, I did notice a few sparks fly.
It may also be due to demonstration purposes too. You can't see much detail when the whole part is being doused in opaque coolant.

One of the youtube comments on this video is "You would think Google wouldn't allow pornography on Youtube"

Right, teeth are much harder to design and mill.

Yeah normally they use an oil based coolant. Those carbide tools are expensive and the fluid extends tool life.

I couldn't imagine what goes into producing the G-code for a part like that. But truth be known the G-code is probably easily produced by software once the proper 3D CAD drawings are made. I have a small desk top 3 axis CNC and I have been fooling with it for about 2 years and still not fully competent in the use of the softwares. I can tell you if you put garbage in, you get garbage out. Your CAD renderings have to be good.
That was a Mori I believe. They are very user friendly with their G code.

Surprisingly, you can get pretty cool CNC machines for less than $30K off eBay.
Also we got to use a CNC for one of our labs ME at LSU. They're so cool to work with and pretty easy.
