          Abstract

          Waspaloy, as a nickel superalloy, is a difficult-to-machine material used for gas turbine engine components that require considerable strength and corrosion resistance at high operating temperatures. The machining of nickel-based alloys generates high temperatures at the cutting tool edge. This research investigated the relationship between cutting parameters and cutting temperature, using a remote temperature measurement method employing an infrared thermometer. In addition, the effects of cutting parameters on surface roughness were examined. Experiments were conducted on Waspaloy AMS5708 superalloy samples and a PVD TiAlN-TiN-coated WNVG 080404-IC907 carbide insert was used during the turning process. It was observed that the highest cutting speed and highest feed rate generated higher temperatures and higher surface roughness. Better surface roughness was obtained with the lowest feed rate, the highest cutting speed and the higher cutting depth. No cutting fluid was used in the experiments.

          Kurzfassung

          Waspaloy als austenitische Nickel-Superlegierung ist ein schwer zu bearbeitender Werkstoff, der für Gasturbinen-Komponenten eingesetzt wird, die eine bemerkenswerte Festigkeit und Korrosionswiderstand bei hohen Einsatztemperaturen benötigen. Die maschinelle Bearbeitung von Nickellegierungen generiert hohe Temperaturen an der Kante des Schneidwerkzeuges. In den diesem Beitrag zugrunde liegenden Forschungsarbeiten wurde das Verhältnis zwischen den Schneidparametern und der Schneidtemperatur untersucht, indem eine Temperaturfernmessung mittels Infrarot-Thermometer zum Einsatz kam. Zusätzlich wurden die Auswirkungen der Schneidparameter auf die Oberflächenrauheit untersucht. Die Experimente wurden mit der Waspaloy AMS5708 Superlegierung durchgeführt und es wurde ein PVD TiAlN-TiN-beschichteter WNVG 080404-IC907 Carbideinsatz beim Drehprozess verwendet. Die höchste Schneidgeschwindigkeit und die höchste Vorschubrate verursachten entsprechend höhere Temperaturen sowie eine höhere Oberflächenrauheit. Die beste Oberflächenrauheit ergab sich bei der niedrigsten Vorschubgeschwindigkeit, der höchsten Schnittgeschwindigkeit und einer großen Schnitttiefe. Es wurden keine Schneidmittel in den Experimenten verwendet.
