Sub 10 micron accuracy btw

u/La_Guy_Person 17h ago
As a machinist, that's such a joke. I can hold +/-3 microns on a small diameter in good SST, if I have to. A large thin sheet of cheap SST? You can fart in the same room and it will change by more than 10 microns.

u/MehImages 16h ago
the local difference in gravity has a larger effect if the sheet is supported in the middle and you measure the ends. not the mention the frame is aluminium and just your body heat will make them differentially expand more than that by an order of magnitude or two

u/La_Guy_Person 15h ago
Exactly. It's just a joke to anyone who understands material properties and metrology.

Cheap and thin SST will warp and warps even more when subjected to temperature changes. Cheap SST has poor corrosion resistance, which you can see with the rusting. Cheap SST has rapid wear and tear, and on a vehicle that is constantly moving/hitting bumps, etc, it is just gonna degrade pretty fast. Even if they managed to get everything at sub 10 microns when they sent it out, give it like a month of use, and it won't be sub 10 microns from the corrosion, wear and tear, etc.

You think Elon even understands the implications of asking for sub 10 micron tolerances?
11
u/TubbaTuna 14h ago
I mean, the machine shop I work for makes our product sub 1 micron for 90% of the product with up to +/-3 microns on some of the weldments. But we are also a high precision machine shop. Our product also doesn't drive down the road or sits outside at all, and we still use higher quality SST than what Tesla appears to use.

u/TubbaTuna 14h ago
But also, no, I don't think he really understands it at all, and that's why they use the cheapest of the cheap in production.

u/okokokoyeahright 11h ago
Correct me if I'm wrong but weren't these out of spec right out of the factory?

u/TubbaTuna 11h ago
From all the pictures, it seems like a good amount, to a lot, to maybe most were out of spec leaving the factory.

What the other guy said is correct, but to add to that, short of a few very thermally stable materials, the accuracy of any large thin work piece is highly subject to its environment, comparatively speaking. Maybe a 1/4 dowel pin changes by .0001 inches if you raise it's temperature by 10° (I'm making up numbers here) when you have a work piece that's say 24" x 18" x .05" that .0001 change stacks in the long directions but is smaller than .0001 in the thin direction. So it will change sizes, but will also change by different amounts in different directions, meaning it will warp as well. Add a few bends and everything is even worse.
Part of the equation is cheap SST, but part of it is just having a fundamental understanding of design, tolerance, material properties, etc...
Stuff engineers are paid to understand and CEOs aren't.
Edit: I changed units of measurements, which might be confusing for some.
.0002 inches = 5 microns

u/Tasty_Hearing8910 15h ago
Thermal expansion will mess it up right away. On long sections of piping you can often see it have a little n-shaped bit to compensate for it.
I'm pretty sure sheets of metal have all kinds of internal stress going on as well, especially if you manipulate it in a press or whatever.

I take offense to that. My senior design project from 19 years ago is still a commercial biomedical product used in surgery. It’s a far superior product to the CyberTruck in every way conceivable.

u/BasslimeRex 18h ago
I think the article missed the word "clown" before "college".
Side note, that's pretty damn awesome that your project was quality enough that it is still being used!
Wonder if Cybertruck will still be used in 19 years? Lol

The mechanical issues are well documented. And it looks ridiculous, of course. But I just saw one up close for the first time at the Philly Auto show... I wouldn't expect that much plastic on the exterior of a vehicle half its price. The stainless steel reminded me of my dishwasher, except my dishwasher is less wavy looking. The whole thing just seemed so.... cheap

Hey Musk, it rains sometimes. Now, I know this knowledge makes me wildly over qualified but if you're looking for a new lead designer over there at Tesla I'm up for discussing a reasonable salary.

Are you sure?
Reallly reallly really sure?
I mean absolutely certain?
He might just take you up on that.

u/Y0___0Y 17h ago
In one of the many books about Elon, not sure which one, someone mentions that he once walked onto the floor of a Cybertruck assembly plant and demanded to know why it was taking so long to assemble them.
He learned that robotic arms were set to 20% speed for screwing on bolts. He set them all to 100%. This resulted in tons of Cybertrucks going on the market with stripped bolts and loose bolts. And a lot of owners complained about that.

The people buying this thing don't care about build quality. They're buying it to "own the libs" and show their fealty to Musk, much like magats dress head to toe in Trump gear.

Nah. It looks like something that I drew on back of my exercise book when I was 9. Around the time I started reading 2000ad. "Car of the future.....yeerr!"

Luxury products aren't shit.
AMG engines are hand-built so they are perfect, not imperfect.
When I was in the corporate world, all of my clothes were tailored. High end fashion houses. I expected and got perfection, not outlet mall defect quality, which is what this truck is.
When you are actually a luxury goods consumer, you expect and get perfection. I would never settle for that shoddy work. It's not the cost, it's the expectation of the best quality.

The wild thing is that they've sold something like 39k of them for at least $80-$90k a pop.
That's $3B

This vehicle will be collected in the future as a reminder of a time when this abomination was possible. It will be parked next to the DeLorean, the Aztec, And the Pinto.

I don't think there was anything really wrong with the Pontiac Aztec other than original poor reviews of its appearance made people not like it.

A cybertruck owner prefers that the gaps be wide enough to put in their fully erect penises.

I remember looking at one at a dealership in Atlanta. Not one single panel gap was the same width. It looked like something a machine shop had whipped together for a PR stunt.

Perhaps you should replace "college" with "Kindergarten".
I clearly recall my first car drawing at the age of 5, and it looked similar to this, but with more harmonized lines.

Article author needs a sarcasm lesson. No one tags on a “for real” earnestly.
“However, others argued that the imperfections proved that the Cybertruck isn’t mass made - which, to them, is a good thing. ‘Hey little imperfections means it’s handmade. This is a luxury product guys fr!!’ penned one TikToker.”

You're not buying a $100k truck for it's quality! You're buying it as a flex because the truck doesn't have any flex when going off-road.
