Just export controls though?

YourAvgDuckHead@discuss.tchncs.de 11 months agoI mean, kind of, yes. CNCs have been one of the big items for export controls. Especially if they can be used to build weapons, parts for nuclear subs, etc.
The post-Cold War control regime is embodied in the 1996 Wassenaar Arrangement, and the 1978 Nuclear Suppliers Group Agreement (NSG) governing the export of machine tools that can be used for nuclear weapons development.

Oh wow, TIL! I guess I’m not surprised, consumer GPS is kneecapped at a lower accuracy for similar reasons

It used to be. It was called selective availability, where the DoD could dial up/down the accuracy for commercial receivers. However, it was discontinued in 2000.

six microns
Given that human chromosomes are on the order of 5 to 10 microns, I am thinking this export regulation doesn’t apply to the hobby market. This is “use the machine in a clean room” level precision.

@FearTheCron @YourAvgDuckHead According to encyclopedia Britannica, I'd say a fairly reliable source, your out by a factor of 100. https://www.britannica.com/science/chromosome
A human blood cell is approx 10 micron long, according to this... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2998922/
Apologies for the pedantry, I couldn't help it.FearTheCron@lemmy.world 11 months ago
Hehe, I just grabbed the number off wolfram alpha’s size comparison. Wouldn’t surprise me if they are wrong, not sure where they scrape the data from. Anyway, my point stands, six microns is still stupidly small. Some dust or hair on the cutting edge and your precision is now out the window.

In the US you don’t need a license to purchase a CNC. Even items with export restrictions like night vision goggles (Under ITAR) can be bought by and shipped to your door. The export controls would only come into effect upon you exporting them.
