Just because you have a copy of it doesn't mean you can make a component with that object's materials capabilities.

The knockoff Michelin military truck tyres is a good example of this.

A mate has some seriously big CNC machine tools. State of the art, highly accurate. He has an OEM contract for parts (not saying who for and what parts) and is the only company globally doing the work.

When we bought our first Mazak CNC machine tool, the contract we had to sign covered numerous stuff that you'd expect - like having power sockets ready for installation and space to unload etc. - and also things I did not; chiefly and most relevantly, that you were under contract not to move the machine to China. Ever. Also that the machine was geolocated and would not work if moved from site without Mazak engineers switching it back on.

Yeah, should be fine.

Love it, the technical bullst way of saying 'we got a few of our less cowboyish technicians to pull out the debris. They've all had a poke around and agree it should be reet'

Probably found a few bonus 'tatoes in the compressor to boot. Job's a good 'un.

could probably fake the gps location with a cheap sdr radio such as hackrf.

(Yeah this guy isn't what I'd call a reliable source, but the original incident was widely reported and I've seen no suggestions that the later picture is faked)

Perhaps waiting for the ground to freeze so it doesn't sink in on the take off roll?

That's only if they moved it onto a temporary matting base so it didn't sink into the mud in the autumn rains, prior to it freezing of course.
If they didn't, it'll stay stuck frozen in the mud until late summer when the ground has dried out.
If they were going to fly it out (big if) they needed to do before the ground softened up......

Personally I don't thing that is ever going to fly again.

Depends if the fence was up quick enough to stop the locals stripping it.

Citizen are much more cunning, they have tilt switches on their lathes so if you move the machine it shuts down and requires an engineer to re-boot it.

Koffman is always excellent. He's giving a bit of an update on what's going on at the moment:

Or a couple of Ukrainians to 'reverse engineer' it!

Cold air will allow the engine to develop more thrust and, I think, the wing can develop more lift as, all other things being equal, there will be more molecules of air supporting it/deflected downward by it.

Yes, when the ground freezes it will support a higher weight. You can flood it which is what some of the Arctic roads do, you drill and pump a river or lake over tundra and if the pump rate and temperature are within range you can drill multiple holes to get the desired depth and weight rating for January. Hence "ice road truckers" haulage.
But this is a ploughed field, not a concrete runway and it is not flat, get the calculations wrong and its yo ass. Given that they are removing the seats someone is not confident its just a Bush runway

Makes no odds. The instant your machine requires a complex spare part or engineer, you;re fked anyway.

The only reason to pay for a high speed/precision machine is because it is high performance, You start throwing random components in and you might just as well have bought cheap crap in the first place.

This is why we don't see more protests from within Russia..

When I first started in engineering if a machine lost its parameters it was 4 or 5 sheets of A4 and half an hour of inputting ones and zeros, 35 years later and our Fanuc Robodrill has thermal compensation software and even Fanuc UK can't give us a definitive answer as to how it works!

That said, the skills of the programmer/setter also play a huge part in the quantity of what comes off the machine. During my apprenticeship it was drummed into me daily that quality was to come first and foremost in everything I did, it was a bit of an eye opener when I saw the st other people considered to be 'precision engineering'

I could Google this but what's "thermal compensation"?

Does that mean essentially, a cooling system?

Metal expands with heat, we all know this, right?

These machine tools are running at micron accuracy over the whole spindle/table length. Any heat effects have to be known and compensated for.

It appears to be adjusting the position of the tool or workpiece to compensate for thermal expansion of either as they warm up from the work done. Fanuc AI Thermal Displacement Compensation

Slightly O/T but it seems China might have some Russian tech on board it's naval vessels.

Re metallic expansion - thanks for that, I had no idea

I understand the need for cooling & temp control, hence my suggestion in my post re thermal compensation being a cooling system - I just didn't know exactly what thermal compensation was, and in this context.

Or is it just making smoke for anti-submarine trials?

Given past history it'll be iffy local knockoffs of Russian tech, so bork³.

The Chinese have a long history of copying the Russians' toys and then using them themselves or even selling them to the Russians' customers. Problem is that, like their knockoff military tyres, the stuff looks similar but it's usually really st.
