Fiber Patch Placement machine, software

Auto sales finally got back above pre-recession levels in 2014 with August sales reaching a seven-year high. After six long years, sales levels have matched 2007’s pace. More importantly, several research groups expect 2015 continue to grow. Today’s Motor Vehicles allows marketers direct access to this healthy industry with continued growth.

Munich, Germany – Cevotec presents the first industrial solution for the automated production of complex carbon composites in high volumes. The novel system is based on the Fiber Patch Placement (FPP) technology that enables the fully automated production of complex 3D composite geometries – in a continuous process from digital design to the final fiber product.

Artist Studio, Cevotec’s easy-to-use CAD-CAM software, significantly shortens the production preparation as it combines two modules for the digital product development: Patch Artist creates patch-based high-performance laminates with curvilinear fiber direction and variable thickness out of any standard CAD geometry. Powerful, proprietary algorithms optimize the patch overlaps to significantly increase the mechanical properties of each laminate. Motion Artist is using this laminate architecture to perform an automatic and collision-free offline programming of SAMBA’s two interacting robots, tests them for collision, and simulates the entire production process.

The high-tech production system SAMBA allows for the precise orientation of each patch to achieve a perfect fiber architecture. Strength and stiffness can be increased by up to 150%. While SAMBA’s two robots precisely position the fiber patches, industrial cameras inspect and document the quality of each patch in a continuous quality report. Thanks to additive manufacturing, the system uses up to 30% less of the fiber material, as patches are only placed where necessary. In addition SAMBA significantly reduces scrap and eliminates additional forming processes through direct 3D net-shape preforming.

The first live demonstration of SAMBA and ARIST STUDIO was at JEC World 2017.
