Impressive, but I'm not a fan of Japanese tools

Scary cool.
That is a serious project! I bet it took the better part of 80 hours to program and perhaps the same for machining and fixturing. In addition to a couple weeks of initial design work plus approval meetings, redesigns, etc. It is stunning, so impressive!

If that 'Tool Path' programming took place in the cnc controller (which I seriously doubt) then I would be very impressed.
This isn't stuff I know much about.
By 'tool path' do you mean the actual series of moves to do the cuts? You'd think that would be precalculated beforehand on a workstation, kind of like a compile step.
Watching that, I wonder how smooth a surface is cut. Can the machine produce a polished surface?
Also, what is the practical range for products that are produced given the price of the box and it's programming? Prototypes only? Super small runs (or to-order) of items? It doesn't strike me as a production line kind of thing. Do people mostly use them to build tooling for plastics?

It is seriously cool how far we have come in such a short time with technology. It occurred to me while watching this though that in a few years, it will be obsolete. With 3D printing just starting to get rolling, it won't be too long before that part (sculpture) can be made faster, cheaper, less waste and just better structurally. Still awesome though.
This is a production line machine, I programmed a live tool lathe for 2 years, similar equipment. The factory was amazing, they have tons of Cnc machines making parts for their children
Any clue what the cost per hour is to run that thing? I'm just trying to get a handle on what the cost of production would be minus the chunk of metal being cut.
480V perhaps 100A, I don't know what the machine costs but perhaps 500,000-1,000,000
so rental on that and a relatively small machine shop environment perhaps 20'x40' could support it. Running this isn't all that expensive.
When I ran a shop it was perhaps a 125,000 machine with a couple of manual mills, lathes for prototyping, a band saw, and all of this supported a very small business of about 6 office & assembly people with just over 1,000,000 sales annually. I was pretty much by myself in the machine shop for the first year while I was programming and making small runs, cool things like hollow spheres (2 halves glued together). The 2nd year I was there I had someone run the lathe while I did prototype work on the manual mills and lathe and did more programming etc.
When I visited the factory (Mazak) in Cincinnati they had a mill like this that was bought by Sukorski to make one part. It had been going through programming and making samples for months at the factory, before it was delivered it was going to be capable of making this one part for helicopters, coming pre-programmed and completely proven out at the factory.

That is exactly what I am talking about and in the software I use I'm able select the type of cutter path, order of cuts, depth, speed - (dependent on type of cutter and material being cut) calc cutter life, and more
With some care and expertise you can get a finished surface but you really need to sharpen the pencil and have exactly the right tooling to do that.
As for the machine itself I would have some concerns for rigidity with an axis behind the quill. 4th and 5th axis trundles have been the norm and have a proven track record of withstanding the rigors and vibration of machining harder alloys with good results
Given the right clientele and a knowledgeable owner/operator a person could retire off that machine.
Don't everyone run out and buy one just yet. As most people who start buying these machines find out rather quickly (including skilled Tool and Die machinist with decades of experience). Marketing a service, managing a business, staying abreast of state and federal regulations while mitigating personal and professional liability in a competitive environment is a vastly different skill set then making the parts
