Abstract
In machining operations, achieving better surface roughness is one of the important goals, furthermore, composite materials are increasingly replacing conventional materials. But their machinability differs from metals, because of anisotropic properties of the composites. In this research, the influence of milling parameters (feed, cutting speed, depth of cut) on surface roughness of bidirectional carbon fiber reinforced composite was investigated. Measurements were performed on both parallel and perpendicular directions of feed motion. Taguchi experimental design was used to determine the optimum milling condition and the effective parameter on the surface roughness. The optimum condition was obtained with a cutting speed of 125 m × min−1, a feed of 0.1 mm × rev−1 and a depth of cut of 1.5 mm. In addition, the most effective parameter on the surface roughness of parallel direction (Rax) was found to be feed and that of perpendicular direction (Ray) was found to be cutting speed.
Kurzfassung
In Bearbeitungsprozessen ist die Verbesserung der Oberflächenrauheit eines der wichtigsten Ziele, außerdem ersetzen Kompositmaterialien immer mehr konventionelle Werkstoffe. Allerdings unterscheidet sich ihre maschinelle Bearbeitbarkeit im Gegensatz zu Metallen aufgrund ihrer anisotropen Eigenschaften. In den diesem Beitrag zugrunde liegenden Forschungsarbeiten wurden die Einflüsse der Fräsparameter (Vorschub, Schnittgeschwindigkeit und Schnitttiefe) auf die Oberflächenrauheit von bidirektional kohlefaserverstärktem Kompositwerkstoff untersucht. Hierzu wurden Messungen parallel und senkrecht zur Vorschubbewegung durchgeführt. Es wurde ein experimentelle Taguchi-Design verwendet, um die optimalen Fräsbedingungen sowie die effektiven Parameter in Bezug auf die Oberflächenrauheit zu bestimmen. Als optimale Bedingungen wurden die Schnittgeschwindigkeit von 125 m × min−1, der Vorschub von 0.1 mm × rev−1 und die Schnitttiefe von 1.5 mm ermittelt. Zusätzlich stellte sich heraus, dass der Vorschub der effektivste Parameter in Bezug auf die Oberflächenrauheit in paralleler Richtung Rax und die Schnittgeschwindigkeit auf die Oberflächenrauheit in senkrechter Richtung Ray ist.
