dcblogs writes: Apple's planned investment of $100 million next year in a U.S. manufacturing facility is relatively small, but still important. A 2009 Apple video of its unibody manufacturing process has glimpses of highly automated robotic systems shaping the metal. In it, Jonathan Ive, Apple's senior vice president of design, described it. "Machining enables a level of precision that is just completely unheard of in this industry," he said. Apple has had three years to improve its manufacturing technology, and will likely rely heavily on automation to hold down labor costs, say analysts and manufacturers. Larry Sweet, the CTO of Symbotic, which makes autonomous mobile robots for use in warehouse distribution, described a possible scenario for Apple’s U.S. factory. First, a robot loads the aluminum block into the robo-machine that has a range of tools for cutting and drilling shapes to produce the complex chassis as a single precision part. A robot then unloads the chassis and sends it down a production line where a series of small, high-precision, high-speed robots insert parts, secured either with snap fit, adhesive bonds, solder, and a few fasteners, such as screws. At the end, layers, such as the display and glass, are added on top and sealed in another automated operation. Finally, the product is packaged and packed into cases for shipping, again with robots. "One of the potentially significant things about the Apple announcement is it could send a message to American companies — you can do this — you can make this work here," said Robert Atkinson, president of The Information Technology & Innovation Foundation.
