And if they can shear the stainless on the Starship then a blank stamping press die would be no problem.

That is a good point, they are already cutting/stamping parts for the Starship. Since the shapes in the Starship are pretty basic I would imagine they are using some sort of CNC shear/brake/roll for these. The CNC cuts and contours the sheet all on one machine.

Heavy Gauge Press Here is a 4000 ton press, they say they can accommodate blanks up to 72” x 100” and the capacity is up to 5/8” steel plate (maybe 5/16” stainless?). There is a video on the page that’s shows it in action. A press this size could likely stamp all of the parts needed for the...

Also, hardening is a very general term. In regards to the Cybertruck I believe they are referring to cold rolled hardening. This is different than what most think of in regards to hardened steel. The term “hardened steel” almost always refers to tempered steel. Usually this involves...

I reference mild steel because that is what is most common, you see it everywhere. If a machine can process 1/2” mild steel then it can typically handle about 1/4” 304L stainless. To estimate capabilities you can use mild steel as a reference just halve it to estimate the machines capabilities...

I can’t image it being a problem. The Cybertruck’s 3mm panels are around 11 ga, this is not a difficult job for a heavy-gauge blanking press. I see pressed parts made from 1/2” mild steel regularly. The stainless is obviously harder but these presses can usually do 1/4” stainless with no...

I do like water jet, it is a cleaner cut than lasers. Lasers cut parts aren’t perfect, they usually have a bit of dross/slag left over that typically needs to be sanded or grinded off. Only problem with water jet is they are even slower than lasers most of the time. Plasma would likely be the...

The tube on CNC lasers are considered a consumable part. They only last so long like a light bulb. And they’re not cheap. Also, CNC lasers take up a LOT of space. The table would likely need to be around 8’x15’ to cut the parts for the Cybertruck, maybe bigger. And they would need dozens...

I can’t imagine Tesla using regular steel for any part of the Cybertruck’s frame. One of the cost savings of using stainless is the ability for the Cybertruck to bypass the paint shop on the production line. All traditional steel (and aluminum) cars are completely dipped in primer after all of...

Good idea!

The specs of the tri-motor are similar to my 2012 2500HD so I was expecting something comparable. HD pickups have jumped up a lot recently with their specs but realistically, the capabilities are still close to my 2012. I agree, aluminum is stronger than mild steel pound for pound. But...

I am just saying the outer "silhouette" can be stamped using a cutting die, no forming or shaping would be needed. The general shape of the flat panel can be stamped out of the sheet instead of being laser cut. This would be much faster and economical compared to the laser.

I am very confident in the Tesla engineers and am sure that the Cybertruck will accomplish exactly what they want it to. I certainly hope they wouldn’t take advice from me. My only concern is that it seems they are not designing the Cybertruck for my intended purpose. I realize I’m being...

My Model 3 an Model Y have the same plastic on the bottom for aerodynamics. This is not structural, it is just for improving efficiency.

I think is is unlikely that Tesla will use laser cutting, as the author states, on the mass produced truck. Laser cutting is a good idea for a one-off product but I doubt Tesla will do this for production. It is much more likely Tesla will use a stamp press to stamp out the shapes of the...
