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.
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.
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.
Batch and queue is the hallmark of a mass production system. Parts are processed, moved in large quantities to the next process, wait for their turn, are processed, and moved as a batch to the next process.
Here’s something you can cut out and hang on your bulletin board if you run a manufacturing company, large or small. I’ve spent nearly 60 years thinking about the factory floor, and here’s how I believe it should be run.
As a result of recent testing under real production conditions, brass proved to machine at extremely high speeds on today’s advanced machine tools with little evidence of tool wear, producing high-quality surface finishes and excellent chip control, reported the Copper Development Association (McLean, VA).
Workers in the oil and gas industry continue to be one of the groups at the highest risk of injuries and fatalities on the job compared to all other U.S. industries. The most recent data from the Bureau of Labor Statistics (2015) revealed that out of 120 workplace deaths in the mining, oil, and gas extraction industry, 74 of them occurred within the support activities for oil and gas operations.
