Comment on Leaked Email Shows Elon Musk Demanding "Sub 10 Micron Accuracy” Cybertruck Parts

While holding this tight of a tolerance is standard for small sinple injection molded plastic part like Lego blocks (0.01mm tol. usually need some really good tooling though), it’s not really possible to hold this tight of a tolerance for large sheet metal construction such as the Cybertruck body (Standard tolerance should probably be in the milimeter range at most. )

So, guess the Cybertruck is never coming out.

I mean, just putting it into the sunlight will probably introduce larger variances than these tolerances from heat expansion alone.

And if dave holds a sheet slightly wrong, it’s going to be slightly bent anyway.

  Exactly the gaps between the panels that make expansion possible are gigantic compared to micron level tolerances.

Not a loss for humanity if that pedestrian killer doesn’t come out.

Also, there is no way to actually measure this tight of a tolerance on large parts such as a car, since the standard methods for this tight of a tolerance measurement is… using a caliper, as using automated optical inspection for every dimension isn’t really feasible.

So, I guess they’ll probably just coddle Musk and make some fake drawings for his eyes only or something, which would only be more useless work for Tesla people.

  We definitely have lasers that can measure this tolereance.

    Yeah, as I said, automated optical inspection isn’t feasible, it would be extremely cost prohibitive to set up laser fixtures for every dimension.

  That’s been their modus operandi from the start.
  
  And if Musk gets too involved somewhere, they just drop a couple of cool words and get him to go on a wild goose chase about shooting people through a massive vacuum canon or something stupid like that.
