The challenge of machining hip replacement implants out of cobalt chrome

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.”

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.

Advanced simulation, new toolpath techniques aid programming of highly complex machinery. CAD/CAM software developers continue to refine simulation capabilities and toolpath techniques that enable programming highly complex equipment including multiaxis and multitasking machine tools.

At EMO Hannover 2017 there were many new cutting tool products showcased, plus there were new cutting tool developments for approximately 130,000 attendees to learn about.

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.
