Trimming Tool for CFRP Rims (English)
Abstract [sv]

Detta examensarbete har utförts på uppdrag av Koenigsegg Automotive AB, som utvecklar, tillverkar och säljer högpresterande sportbilar. Företaget erbjuder fälgar tillverkade helt i kolfiberkomposit, som ger betydande viktbesparingar i jämförelse med traditionella metallfälgar.

Efter tillverkningen kräver fälgarna viss bearbetning vid anläggningsytan mellan fälg och däck. Syftet med examensarbetet har varit att undersöka möjligheten att utföra bearbetningen av fälgarna in-house i Ängelholm, och målet har varit att konstruera en maskin för detta ändamål.

Projektet inleddes med en litteratursökning, där svårigheter och möjligheter gällande bearbetning av kolfiberkompositer undersöktes. Till följd av de undersökningar som gjordes, valdes bearbetningsmetoden svarvfräsning och ett antal konstuktionskoncept genererades. Genom ett antal utvärderingar utvecklades ett speciellt koncept vidare till ett komplett produktförslag.

Produktförslaget är komplett med analyser, beräkningar samt tillverkningsunderlag, som ger uppdragsgivaren bättre insikt i sina möjligheter. Även underlag som tillåter en framtida CE-märkning har tagits fram. Projektet har följt Fredy Olssons konstruktionsmetod.

Abstract [en]

The following thesis has been performed in cooperation with Koenigsegg Automotive AB, which develops, manufactures and sells high-performance sportscars. Koenigsegg offers rims made completely from carbon fiber composite, which yields substantial benefits in stiffness and weight compared to their traditional metal counterparts.

After the manufacturing of the rims, some trimming is necessary in the contact surface between rim and tire. The purpose of this thesis has been to examine the possibility of performing the necessary trimming in-house in Ängelholm, by designing a special tool.

The project began with a literature study, where possibilities and difficulties of machining carbon fiber composites were examined. As a result of the study, the manufacturing process turn-milling was chosen, and a number of concepts were generated. Through a series of evaluations, one concept was further developed to a final product.

The suggested product is complete with calculations, analyses and drawings, which gives Koenigsegg a better insight of future possibilities. A solid foundation for future CE-marking has also been produced. The project has followed Fredy Olssons methods of Engineering Design.
