The Brazil International Machine Tool and Industrial Automation Exhibition opened on May 9 and runs through May 13 at the São Paulo Expo Exhibition & Convention Center, the largest and newest show pavilion in Brazil.
Carbon fiber is a magical material. That or similar comments were heard over and over from Roosevelt High School (Seattle) students attending a Composites 101 Workshop held at the National Resource Center for Materials Technology Education (MatEdU), a National Science Foundation Advanced Technological Education (ATE)-sponsored program at Edmonds Community College (Lynnwood, WA).
As inventive and imaginative as 3D printer technology is, so are the materials that R&D labs have come up with to build parts, including conductive thermoplastics.
Nothing seems so obvious in subtractive machining than that milling and turning processes really are very different: single point vs. multipoint tools; rotating workpiece vs. rotating tool; static tool vs. rotating tool, etc.
Scientists at Rice University (Houston) are smashing tiny silver cubes into a hard target in order to make these metallic microcubes ultrastrong and tough by rearranging their nanostructures upon impact.
The simple proposition that no two automation solutions using robotics are alike because no two manufacturing processes are identical presented a major challenge to Daniel Drennen of Deshazo LLC (Alabaster, AL).
Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.
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.
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.
Materials science has opened new possibilities for designers of cars, planes and other products. Metal alloys are now as precisely engineered as they are machined. The result is longer lasting, stronger parts. But with a wider selection of materials comes risk—how can you be sure that one piece of gray metal stock is different than another? Careful warehousing procedures and paperwork only go so far.
