          Abstract

          Composite materials such as fiber-reinforced composites (FRP) are extensively used in today's industries such as aerospace, automotive, and shipping because of their high specific strength and high specific stiffness. In addition, they have good thermal resistance, corrosion resistance, damping resistance, and dimensional stability. But, due to the inhomogeneous composition of these materials, machining of composite materials becomes a major concern in the industry. For the present study, machining was carried out at a CFRP composite pipe with bidirectional carbon fiber. Based on the experimental results, regression analysis was conducted to determine the input-output relationships of the process. A mathematical model was developed to predict the responses, and correlation graphs were plotted. The regression equations were then plotted and the effects of each process parameter on the response were analyzed using the response surface methodology. The process parameters were then optimized using genetic algorithm to yield minimum cutting force and minimum surface roughness.

          Kurzfassung

          Kompositwerkstoffe, wie zum Beispiel faserverstärkte Komposite (fiber-reinforced composites – FRP) werden sehr häufig in der heutigen Industrie wegen ihrer hohen spezifischen Festigkeit und Steifigkeit verwendet, wie zum Beispiel im Bereich des Flugzeug-, Automobil- und Schhiffbaus. Zusätzlich besitzen sie gute thermische Resistenz, Korrosionsbeständigkeit, Dämpfungsfähigkeit sowie Dimensionsstabilität. Aber auf Grund der inhomogenen Natur dieser Materialien verursacht die maschinelle Bearbeitung von Kompositwerkstoffen erhebliche Probleme in der Industrie. Für die diesem Beitrag zugrunde liegende Studie wurde ein CFRP-Kompositrohr mit bidirektionaler Carbonfaser bearbeitet. Basierend auf den experimentellen Ergebnissen wurde eine Regressionsanalyse ausgeführt, um die Input-Output-Verhältnisse des Prozesses zu bestimmen. Es wurde ein mathematisches Modell zur Vorhersage der Antworten entwickelt sowie Diagramme für die Korrelation aufgestellt. Die Regressionsgleichungen wurden dann aufgetragen und die Effekte jedes Prozessparameters auf die Antwort mittels der Antwort-Oberflächen-Methodik analysiert. Die Prozessparameter wurden dann mittels genetischem Algorithmus optimiert, um die niedrigsten Schnittkräfte und Oberflächenrauheiten zu erreichen.
