Abstract
Parts made of composite materials are generally produced by near-net-shape technology. However, additional machining operations such as drilling are often required to facilitate components assembling. Drilling of composite materials is also a common process in the assembly of aerospace and automotive composite structures. During drilling, unlike the conventional materials, a few damage forms may take place. Among these damage forms, the delamination is the most important one. Therefore, the experimental studies carried out on drilling of CFRP composite materials for determining optimum processing parameters are of great importance. In this particular study, delamination in CFRP composites caused by drilling was investigated. The composite material was drilled under various spindle speeds, feed rates and drill point angles. The results showed that delamination and thrust forces were affected by cutting parameters. It was demonstrated that feed rate and drill point angle make the largest contribution to the overall performance.
Kurzfassung
Teile aus Kompositwerkstoffen werden generell mittels Near-net-shape-Technik hergestellt. Allerdings sind häufig zusätzliche maschinelle Bearbeitungen, wie zum Beispiel Bohren, erforderlich, um den Zusammenbau der Komponenten zu ermöglichen. Das Bohren von Kompositwerkstoffen ist zudem ein übliches Verfahren bei der Montage im Flugzeug- und Automobilbau. Während des Bohrens können im Gegensatz zu konventionellen Werkstoffen eine Reihe von Schädigungsarten auftreten. Darunter ist die Delamination die wichtigste Art. Daher sind die hierzu durchgeführten experimentellen Studien zum Bohren von CFK-Kompositwerkstoffen, um die optimalen Prozessparameter zu bestimmen, von großer Bedeutung. In der diesem Beitrag zugrunde liegenden Studie wurde die Delamination infolge Bohrens in CFK-Kompositen untersucht. Hierzu wurde der Kompositwerkstoff bei verschiedenen Spindelgeschwindigkeiten, Vorschubraten und Bohrspitzenwinkeln gebohrt. Die Ergebnisse zeigen, dass die Delamination und die Schubkräfte durch die Schnittparameter beeinflusst werden. Es wurde gezeigt, dass die Vorschubrate und der Bohrspitzenwinkel den größten Beitrag zur Gesamtleistung liefern.
