Elon was probably speaking generally when what probably happens is the stamping dies break much sooner than normal.But then you’re merely describing how every such machine is incrementally “broken” by any use of it.
If that’s all EM meant, it’s uninteresting rather than incorrect.
Good point,Anything that is welded would need to be refinished due to the heating likely causing color changes in the steel so I imagine there won’t be much welding or they will lose the benefit of no paint. My vote is no welding. They will use structural adhesives to combine parts.
Turns the corner from a point to a spring.At tight bends a hole is drilled to relieve stress. The hole is drilled when it is a flat sheet. This would then be filled with an adhesive to maintain water tightness. Bend radius and thickness of material determine the size of the whole.
Beyond 90 degrees the need is greater due to the concentration of stress. Same principle as a stop drill for a crack. The hole created a smooth transition where there would have been a tight compression or expansion.
seems to me, that this is all missing their asserted hypothesis: that a SS with the hardness described by EM would not permit of such stamping without unacceptable failure rates of the SS itself - it’s like attempting to bend a cracker: it’s not a problem to apply the effort needed to get the material to respond, the problem is that crackers don’t respond to that effort by bending.Elon was probably speaking generally when what probably happens is the stamping dies break much sooner than normal.
Stamping dies are expensive and might take months to get replacements.
Stamping 3mm cold-rolled 30x stainless steel into the shape of a traditional Ford F-150 front fender with it's sharp curves is extra rough on the stamping machine & the stamping die.
Even with 1-2mm regular stainless the die might only last 20 stamping cycles vs normal 2,000-50,000.
Makes a huge difference in cost per piece.
In the past Ford actual made a few (very very few) vehicles with stainless steel outer bodies and those were made with much less than 3mm cold-rolled 30x stainless steel
Door handles like they have on the Model X, where there is nothing to pull but just touch, are only aesthetic anyway...might just as well eliminate them and save the hassle/cost/effort. This way those who would mess with the handles have to think of some other way to get in.Yup, cost and production time delay might be main reason for no door handles on Cybertruck.
Maybe Cybertruck is not all made out of 30X crackers.seems to me, that this is all missing their asserted hypothesis: that a SS with the hardness described by EM would not permit of such stamping without unacceptable failure rates of the SS itself - it’s like attempting to bend a cracker: it’s not a problem to apply the effort needed to get the material to respond, the problem is that crackers don’t respond to that effort by bending.
To the degree that is true, it would seem to equally irrelevant whether a press might become damaged by repetitively chewing up useless pieces of failed SS
Seems like saying, “the reason we don’t bend crackers with our hands is that the sharp edges chew up your skin”
I think that they will be able to punch very large holes out of larger pieces and end up with less waste than you imagine.This bend at the red arrow needs to be welded, otherwise there is heaps of waste.

A-pillars, O.H. glass roof framework beg extruded form factors. Tesla IIRC admitted B-pillars are not S.S. but stamped. The bottom rail is up for grabs, either folded or extruded.
the heck are y’all two talking about?!Who said they are stamping at all?
If they are stamping what exactly is being stamped? To cut it and to form it or just one of those?
The goal is 250k off the rip, well stated publicly already.The Truth About Cybertrucks
More likely, the truth is that the Cybertruck is intended to be a low volume production because the chosen manufacturing method does not lend itself to high volume production.
again, those posted articles are from the days after the initial releaseThe goal is 250k off the rip, well stated publicly already.
