Constant refinement of medical machining from tooling design to finished product requires not only the ability to handle a broad range of plastic and metal materials but also to achieve predictable results—particularly in the face of strict regulations.
When the Italian company JDeal-Form (Oleggio, Italy) started using additive manufacturing to apply a micronized polymer coating to the underwire tips and bra straps it sold to brassiere makers, CTO Davide Ardizzoia grew frustrated with his AM vendor’s constant lateness.
Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."
At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.
Four universities—Iowa State University, University of Minnesota, University of Wisconsin-Madison and North Dakota State University (NDSU)—competed in the inaugural 3M Industrial Adhesives and Tapes Disruptive Design Challenge (DDC) at 3M’s headquarters (St. Paul, MN), Friday, April 13.
The National Center for Manufacturing Sciences (NCMS) (Ann Arbor, MI) and Moog Inc. (East Aurora, NY) have signed a contract to perform co-funded work in support of applying Moog’s VeriPart solution, adapting blockchain technology for additive manufacturing.
Machining aerospace materials is a challenging task. Not only are machining operations tightly controlled, a wide variety of workpiece materials are employed, including aluminum, titanium, and carbon-fiber reinforced plastics (CFRPs). The following is a brief guide to cutting tool options for successful machining of airframe components. All of the tools referenced are manufactured by Mitsubishi Materials.
Celebrating its 80th year, Kennametal, the Latrobe, (PA), tooling manufacturer, says it has solved the age-long problem of tool stability when drilling in deep cavities, alongside tall shoulders, and past bulky fixtures. Reaching deep inside a workpiece to drill holes can be challenging.
Should the US Copyright Office oversee whether 3D printer operators can use feedstock not approved by their machine’s maker to turn out medical devices or airplane parts, or is that the role of the US Food and Drug Administration (FDA) and US Federal Aviation Administration (FAA), respectively?
Additive manufacturing (AM), or 3D printing, is a fast-growing field that offers many advantages over traditional techniques. It can create more complex parts than either machining or casting, can fuse different materials together, and is sometimes less expensive in low-volume or prototype applications.
