Milling and drilling of composite materials for the aeronautics

The JEC Composites website features an interesting paper presenting the issues around the milling and drilling of carbon-fibre-reinforced composite panels. The paper includes a reminder of the material’s specific properties, the technical equipment required, the potential conditions, and distinctive features about the way machined surfaces degrade. The text also discuss the use of PCD tools,…

Reduction in dynamic friction in composite material

We got an interesting question from a reader about cutting forces that we want to share. Eleanor Merson, Research & Development Manager at Sandvik Coromant in Sheffield, gives her view on cutting parameters and thrust forces. Question: It has been widely speculated that at higher cutting speeds in drilling of composites, cutting forces are relatively lower…

CFRP edging with MDI technology

A Barcelona-based customer was struggling with edging carbon-fiber-reinforced polymer (CFRP). Even though the customer had tested all available alternatives, they weren’t getting the results they wanted. Finally, the foreman contacted experts at Sandvik Coromant. We had a long discussion about fiber machining and in situ analysis of delamination problems and durability of the edging operation….

European Composite Application Center opens

Sandvik Coromant recently opened the European Application Center for composite machining as a resource for manufacturers looking to optimize the production of composite components. Located in Orléans, France, the new Application Center supports European markets and serves as a specially-manned competence facility for customer projects. It aims to deliver complete processing, programming, testing and machining…

New toy for the Research Center!

A new temperature-measuring infrared camera recently was delivered to the research center in Sheffield, U.K. The camera takes up to 120 images per second and by using it, we can see which parts of the tool that gets hottest. With the results at hand, we can tweak our drill designs and recommended conditions for customers…

Sandvik Coromant – Atlas Copco collaboration

One of the world’s leading suppliers of jet engine thrust reversers turned to Zenmar, an authorized Atlas Copco distributor, to automate the drilling process of its thrust reverser aft cowl application. Materials included both 15-5 stainless steel and Inconel, both very hard steel alloys frequently used in jet engine manufacturing. The total stack consisted of…

Simulations reveal a promising future for unidirectional composite drilling

I attended Third Wave Systems’ annual users’ conference earlier this May in Minneapolis to witness the host of new developments for myself, and see how others are using their products. I was particularly interested in the AdvantEdge software, designed to model different cutting processes. The Third Wave team is currently developing code to simulate composite…

Technology developments in composite material and tools

When it comes to composite material, everything develops rapidly – design and innovative solutions as well as marketing of new products. Did you know that it is now possible to cut composite fibers without cutting the tensioning paper? But, what happens in the area of tool manufacturing for composite material? Definitely the tool development is…

Sandvik Coromant and its partner Precorp to attend world’s largest composites show!

Taking place at Porte de Versailles, Paris on 27-29 March, JEC Europe 2012 is a must-attend event for any engineer with an interest in composites. The globe’s greatest minds and proven innovators will assemble to offer technologies and solutions for the most challenging applications. Among the exhibitors will be cutting tool and tooling systems specialist,…

Composite Machining seminar in Shanghai – Success!

Happy Chinese New Year! We have reason to celebrate! With the growing international subcontraction business and China’s jumbo aircraft development project (C919), Sandvik Coromant GCR sees a great potential for cutting tools for composite materials. Aerospace customers are eager to obtain the best application knowledge, so Sandvik Coromant decided to have a technical seminar in cooperation with Beihang…
