MIT has developed a Machining Variation Analysis system that allows designers to create machine tools on the computer and use those tools to virtually machine parts and predict the exact shape of a part given any error that may exist in the machine tool. "Before the MVA, machine-tool designers could not predict the effects of the dozens of error sources that plague a real process," said MIT Professor Alexander Slocum of the Department of Mechanical Engineering. "Every time a machine was designed to make a new part, the company took a gamble. The MVA takes the risk out of developing new manufacturing equipment." With MVA, the user provides information including the geometry of the part and sources of error in the machine's operation. With these parameters, MVA determines the exact shape of the part including all the consequences of the specified errors in machine operation. Slocum developed the MVA with Professor Kevin Otto of mechanical engineering, Daniel Frey of MIT's System Design and Management Program, and colleagues from the National Institute of Standards and Technology and the Landis Division of Western Atlas, Inc.

Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
