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.
Not a loss for humanity if that pedestrian killer doesn't come out.
This thing is going to be just as dangerous for the drivers too, won't be legal to sell in many jurisdictions.
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 account for the heat expansion are gigantic compared to micron level tolerances.
On the other side, one may be able to fry an egg on the hood
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.
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.
I think I am going to give my main project manager a nice gift for Xmas this year. This is just a small reminder of how much worse I can have it.
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.
Maybe all this is on purpose so he can blame the factory workers on why the product never materialize and he can avoid the shame of having unsold inventory as people realize the car is fugly
Even the heat of the day would make a panel warp more than is being stated. It is just sales BS to make him look good.
No two cars are ever the same. Even with robots panels move in jigs. There is usually a guy at the end of a line who has the job of body adjust. Paint shops warp the crap out of a car body in the baking phase.
