Composites Machining for the Lockheed Martin F-35

How can precision machining be made less expensive? That question—in one form or another—occupies much of the attention of various Lockheed Martin engineers. If the same kind of precision five-axis milling used in the F-35 skin parts could be applied cost-effectively throughout the plane, the result would be higher-performance aircraft that are far less expensive […]

Tool solutions for machining composites

There is a continuing demand for tool innovations to cut, shape and drill composite material applications in almost every industry sector. Composites, each presenting a unique composition, are rapidly replacing traditional building materials – steel and aluminium in aerospace applications, as well as within marine, building supply and automotive industries. Commercial and military aircraft now […]

Custom Cutting Tools Used to Machine CFRP

Surface image of Diamond Coating at  x5000 magnification. As an exhibitor at WESTEC this year, I was amazed by the number of times I was asked the same question: “How do I machine CFRP?” It’s a question I often field as the sales director of Diamond Tool Coating.  But the frequency with which it was […]

Coated Carbide Cutting Tools Offer Superior Cutting Geometry and Longer Tool Life

After rigorous testing, Lockheed Martin chose coated carbide tools made by AMAMCO Tool (Duncan, SC) for machining composite wingskins on the F-35 strike fighter project. When Lockheed first began assessing router and drill tools for the plane’s production in its DST machining center (Dörries Scharmann Technologie GmbH, M önchengladbach, Germany), it used a polycrystalline diamond […]

Super Drills

More sophisticated drills enable shops to tackle superalloys with ease No one can put as fine a point on how complex drilling has become during the past few decades than a veteran machinist like Peter Diamantis. Diamantis recalled that when he started out 30 years ago drills held a status in the tooling hierarchy not […]
