On top of my head, Kalashnikov is making auto CNC's and now 3D printer+CNC mixed.
Rosatom as well.

I wonder if they have a manual mode on their CNC machines, creating prototypes with CNC would be painful, but CNC is wonderful for mass production.

For a prototype it would be quick and easy to reshape and redesign parts on the fly when needed... then when you have what you want you can then use normal materials and shift to mass production.

Since all is now designed using CAD software why CNC should be bad for prototyping? all data, settings are already in digital form?

Clearly the words of someone who has never seen the process of setting up a CNC machine before.

than before. Back in the good old days one had to program in NC specific languages. Today you do not have to touch
any code for an NC machine.

The Soviets didn't even bother designing their own shape for Buran after NASA spent 2 billion dollars on thousands of external shapes based on the aerodynamics of an object entering the atmosphere from orbital speeds with the materials and production limitations of the time.
They adopted the shape and saved an enormous amount of time and money... and it worked rather well despite being fundamentally different in actual design... the Buran is a glider launched on a rocket, while the Space Shuttles are super heavy aircraft with enormous external fuel tanks for the fuel energy to get to space and huge solid rocket boosters or JATOs to get moving.
It was only after the US stole the maths of radar propagation from a Russian scientist that their ability to create stealth aircraft actually became practical and useful... physically testing a few wooden shapes a week just does not cut it.
Modern CNC machines use digital models... everything is digital.... early CNC machines are like early mainframe computers with punch card programming.
You can now get three D printers that can take lasers or cutting tools or plastic or metal powder 3D printer attachments... very versatile and clever to make parts or layer by layer build parts, or burn shapes in materials etc etc...

posing together with the model. Maybe the Soviets "stole" some of the US design, but they would not need to. They clearly could
design aircraft without those overrated supercomputers (which were junk in the 1970s by even late 1980s standards). The Shuttle
and Buran shape is dictated by the function. A glider entering from space into the atmosphere and being able to carry a bulky payload
on the way up (or down). It really is a case of minimizing around the same local minimum in design parameter space. Giving either
of them distinctive characteristics in wing shape and body shape introduces spurious cost and degrades reliability. The only "theft"
is the absolute size. Here I see the decision being made to follow the US model to achieve parity. Making it smaller would reduce
its potential and making it larger would increase cost of the whole system including the launcher and would also reduce reliability.
I doubt that the USSR stole the Shuttle tile technology since it had enough scientific base to come up with its own light ceramics
and the glue to attach them to the Buran fuselage.
The Toshiba NC "scandal" was more plausible since it could have involved submarine screw shape rendering flexibility. But then,
the USSR would still need its own shape design and had the deep knowhow to achieve this.

The whole "Toshiba affair" is something I find particularly bizarre.
We are talking - I will say that again - a nation that operated its own desigh&build subs since 1880.
Holding all the records you could get, one by one. Fastest, deepest diving, bigger ice crushing capability, biggest etc. The only one in the world, where the designers were focused enough on safety, to place a rescue chamber as a piece of standard equipment. And this rescue chamber has proven working&saved the lives of the Komsomolec crew.
Advanced and automated enough, to have crews numbering half of the competitors while serving the same tasks.
Enough to compare Lira class. It used to be a submerged Ferrari if we compare that to its opponents.
And now, we are being told, that all that record achievements were a piece of shit because they didn't have the machines good enough to make a propeller right?
Even if so, with the manpower in the possession, they could shape the propellers by hand if needed

The reality is that the Buran differs from the Shuttle even in aerodynamics. Its aerodynamic quality is BETTER. Just because the USSR had a tremendous experience in creating aircraft, and such world-class scientific centers as GLITZ and TsAGI.
Shuttle and Buran are similar only because they have similar functions. However, upon closer examination, they are completely different, even at the level of concepts. The Buran has more optimal aerodynamics, higher energy capabilities, and is more flexible in application. You can overlay the contours of the Buran and the Shuttle - and see that they are different.

The shapes are nearly identical because they consist of three elements:
1) Delta wings blending into a lifting body.
2) "Squared off" cylinder fuselage to accommodate more payload volume.
3) Aircraft type nose section.
There is not much room for flowery design in all three categories. Some details are nearly identical. They could have
been token differentiated but why bother. The American design experience was absorbed by the Soviet designers of
the Buran. It is not embarrassing and Americans should take some pride and credit. But Americans also love to
spread shit around that they were totally ripped off. Like their drivel about the Tu-95 being a copy of the B-29.

The Soviets certainly had small space plane designs which they tested well before Buran... but the aerodynamics capacity and ability of the Soviets should not be underestimated.
They can often adopt ideas, but normally will adapt them to their own needs and also apply new technology to make them better.
A space shuttle made during that period is not just limited by aerodynamics... it has to have an internal volume to take the crew and any payload and equipment the Shuttle is to use during its entire life span without needing modifications of course.
The design is also limited by knowledge of the boundary layer of air and space and aerodynamics at mach 20+ is not a solid fully researched area back then.
Another factor is also materials science and manufacturing capacity... getting a US copy to copy directly does not help a lot if you don't have the materials or the production capacity to make it to that level of precision.
Variation on the MiG-15s wing was about 5mm which is fine for a subsonic jet, but would be catastrophic for a stealth aircraft, and could be fatal for a supersonic fighter in terms of flight performance...
The key difference between the shuttles is that if you are building a new space station you can take the Buran off the back of the Energyia rocket and place a complete section of a space station with a nice aerodynamic fairing up to 120 tons in weight and launch it in one piece... 3-4 launches and you could build a rather useful space station... where each launched block locks together easily and simply.

Russia "copied" the Shuttles overall shape just like Sierra Nevadas "Dream Chaser" is a copy of the BOR-4 subscale lifting body test vehicle.

The sentry robot used at the Vostochny Cosmodrome (named 'Marker') is an autonomous system. That is, it is a real
robot and not a remote controlled toy. It was tested by being sent on a 100 km trip where only the end point was issued
as an instruction.
1) It determined the path by itself.
2) It launched a recon drone 20 times all on its own initiative. This was not preprogrammed.
The robot has a AI (seems like world class to me) that engages pattern recognition of the images it gathers through
its cameras and its drone.
The successor model to Fyodor is being developed and will be released in 2023. It will have tactile sensors which
indicates to me that its AI, developed with the experience from Marker, is expanding.
Both the Marker precursor and Fydor were the focus of derision by the usual suspects wanking themselves silly
about Russian genetic inferiority. Now these clowns have nothing to say and the US press is sounding alarms
about Russia developing advanced robotics tech.

and I'm happy about non military part here. Just because , I am sure military robots in Russia will do well so I don't really worry about them .
However applying this hi tech in civilian market is to me awesome news! Agricultural robots are really future market you cannot neglect, logistics too or medicine. I hope industrial will follow.

Even remote surgery where a doctor in one part of the country can perform operations in a distant and more remote part of the country... which could lead to an AI surgeon that can perform more minor surgeries freeing up doctors for more difficult ops either locally or remotely.

The problem with nuclear is that in high radiation environments advanced electronics with microcircuits tend to glitch and fail.
So you end up with quite different solutions than you would otherwise.
