The manufacturing processes shown in the video have been commonplace for 25 or more years. Amazing, no. Interesting to those who are not familiar with manufacturing automation, perhaps.
If the general public thinks that video is amazing, then perhaps the general public has no idea how advanced the manufacturing sector really is.
yes, i have "no idea how advanced the manufacturing sector really is". i can only imagine. it's just not my profession.
but the point here is, i think, that the vast majority of people (including myself) take it for granted. we don't really care about how the iphone's made but when we have the chance to actually see automated manufacturing we are (or at least i am) completely amazed by what we as humans are able to do with materials coming out of bricks of stone from below earth surface. i'm amazed that people invent machinery so acurate and precise creating clear, polished surfaces for the end product. pressing metall into a desired form. creating glass to be bend and scratched like crazy.
i could stand at a production line and watch that stuff all day.
From 1979-1984, I programmed and operated NC & CNC lathes and milling machines that made parts far more complex and precise that what they are showing. One of our customers was the beer bottling industry.
In the period from 1984-89 I watched pick & place circuit board assembly, pick & place robotics, robotic polishers, robotic bead blasters and spray painters operate in local machine shops, automotive plants and electronics manufactures.
I've never worked in a shop that punched out cylinders, but I'm sure that the process they are using for punching out the cylinder from a block of aluminum is how beer cans get made.
You may well be right, but I think the key claim is this:
"Most metal stampings go through one or two die tools to produce the final shape. With the Mac Pro though, the challenge is to produce a massive amount of plastic deformation without tearing, rippling or deforming the perfect cylindrical surface."
and, below the figure:
"The results of the first (of between 4 and 5) deep draw stamping operations. Notice how the Mac Pro part is nowhere near the final length."
As I'm sure you know, there's a big difference between a single-use aluminium can, which is both small and thin, and a large part like this, which has to have both structural stability, very high dimensional tolerances, and a good surface finish. That said, you obviously know more about this than I do, so maybe you can comment on the quotes from the article?
The processes in and of itself aren't amazing, I think what's amazing is the scale that Apple operates on. Not many other PC manufacturers use CNC milling as extensively as Apple. Here's an interesting video with Jony Ive talking about the process: http://youtu.be/nUHROAtyGIg?t=2m29s
The making of the fancy, hip Mac Pro is really-really simple compared to a much less fashionable Korean car. Except Hyundai users usually don't spend their time watching videos on car manufacturing. :)
Sometimes, however, simple things can require a lot of expertise: during the '90s, many jet builders went to Shimano and Campagnolo and sought help in manufacturing small, but reliable metal parts for airplanes as the bicycle part industry was quite ahead in this field.
