Whereas carmakers akin to Mercedes-Benz have mentioned automation has limitations, Musk has pressed on with plans to create a hyper-automated manufacturing unit, which he refers to because the “alien dreadnought”, or “the machine that builds the machine”.

Tesla’s elevated reliance on large-scale aluminium elements may carry new manufacturing challenges
Tesla Chief Govt Elon Musk warned on Tuesday in regards to the difficulties of dashing up manufacturing as an professional cautioned the carmaker’s elevated reliance on large-scale aluminium elements may carry new manufacturing challenges. Whereas carmakers akin to Mercedes-Benz have mentioned automation has limitations, Musk has pressed on with plans to create a hyper-automated manufacturing unit, which he refers to because the “alien dreadnought”, or “the machine that builds the machine”.
“The intense issue of scaling manufacturing of latest expertise shouldn’t be effectively understood. It is 1,000% to 10,000% more durable than making a number of prototypes. The machine that makes the machine is vastly more durable than the machine itself,” Musk mentioned on Twitter.
Musk’s warning comes forward of a “battery day” afterward Tuesday, when Tesla is predicted to unveil steps to spice up battery manufacturing.
For its new Mannequin Y, Tesla plans to interchange 70 parts glued and riveted into the automotive’s rear underbody with a single module made utilizing the world’s largest aluminium casting machine in its new manufacturing unit in Brandenburg, close to Berlin.
Automotive our bodies have historically been made by assembling a number of stamped steel panels, a method which has helped create crumple zones to soak up vitality throughout a crash, however Musk is charting a brand new course on the Brandenburg plant.
Whereas casting may scale back the variety of meeting steps, bigger aluminium elements are extra liable to deformation, in response to Professor Martin Fehlbier at Kassel College in Germany.
“On paper it seems to be simple,” mentioned Fehlbier, a former head of foundry expertise at Volkswagen Group, which pioneered aluminium development methods at its Audi model. “The small particulars could cause you to burn by means of a variety of money.”
The bigger the half, the extra consideration must be paid to heating the shape, since molten aluminium must fill out the solid, Fehlbier mentioned, including the thinner the half being made, the extra doubtless the steel will cool earlier than filling out the shape.
In contrast, the warmer the shape, the longer the element has to chill earlier than the subsequent manufacturing step, which might restrict the general velocity of manufacturing, Fehlbier mentioned.
Cooling aluminium too rapidly can lead a element to deform, and altering the consistency of the steel has big implications for the price of every element in addition to on potential crash take a look at behaviour, he added.
“The Audi A8 has began to make use of extra metal elements as a result of a brand new aspect crash take a look at in the USA can’t be handed utilizing simply aluminium,” Fehlbier mentioned.
It isn’t the primary time Tesla has confronted challenges with new manufacturing methods. The electrical carmaker was compelled to fly in a brand new manufacturing line from Germany to Nevada in 2018 to repair a producing line after robots didn’t coordinate seamlessly.
