Masters of Manufacturing: Herbert B. Voelcker July 1, 2009 A self-described “river rat” during his teenage years, Herbert B. Voelcker grew up in the small town of Tonawanda, NY, just north of Buffalo, where as a young man he grew to love the water, boats, and steam engines. His early fascination with how things worked eventually led him to study mechanical engineering at the Massachusetts Institute of Technology (Cambridge, MA), and to embark later on a greatly varied technical career highlighted by his research into the mathematical foundations for 3-D solid modeling.
Extrusion and Drawing Knowledge January 2, 2015 Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.
Geometry Lesson Teaches Corvette How to Lighten Up October 14, 2016 It’s been almost two decades since the C5 Corvette hit the streets with its groundbreaking chassis built around hydroformed steel bumper-to-bumper frame rails. The technology gave engineers a chance to create components that were both lighter and stiffer than traditional stamped and welded assemblies.
Solutions for Difficult Machining January 1, 2009 The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.
Tooling to Match Composite Production April 1, 2009 It’s getting harder to imagine any market that isn’t benefiting from the latest developments in parts manufactured from advanced composites. “Advanced composites will arguably dominate consumer and production products, especially in the near future,” says Bert Erdel, industry consultant and executive technology advisor, Morris Group Inc. (Windsor, CT), “as they have begun to gain wide acceptance in solving energy-related issues.”
Companies Push the Boundaries of 3D Printing Composites October 26, 2016 Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.
Searching for the Perfect Lightweighting Recipe September 1, 2016 Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.
3D-Printed Parts Restore Cars’ Glory August 12, 2016 Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.
Honeycomb Heroes: Making Composites for Aerospace June 24, 2016 There’s an old saw that if bumblebees were aeronautical engineers they would know they can’t fly. Quite apart from the miracle of their flight, bees also happen to make a lightweight structure of surprising strength, just the sort of thing you’d want if you were building aircraft: honeycomb.
