Abstract
In this study, the machinability of Stellite-6 coating was examined using a ceramic cutting tool. Orthogonal tube-cutting experiments were performed on a lathe and the data collected was evaluated by analysis of variance (ANOVA) to find out the percentage contributions of the key factors. Whisker reinforced ceramic inserts with ISO tool designations RNGN 1907 00T01020 were used for the machining trials and round type cutting tool inserts which are common in the manufacturing industry were chosen. Taguchi design of experiments was implemented to determine the optimal cutting parameters for analyzing the effects of the cutting speed and feed rate on the surface quality. Four cutting speeds and three feed rates were used during the turning operations to produce the regression model for Ra (average surface roughness) in terms of the actual parameter values. Hardness of the cutting inserts gets affected significantly at higher feed rate.
Kurzfassung
In der diesem Beitrag zugrunde liegenden Studie wurde die maschinelle Bearbeitbarkeit einer Stellit-6-Beschichtung mittels eines keramischen Werkzeuges untersucht. Hierzu wurden orthogonale Rohrschneidexperimente auf einer Drehbank durchgeführt und die ermittelten Daten mittels Varianzanalyse (ANOVA) untersucht, um die prozentualen Einflüsse der Schlüsselfaktoren herauszufinden. Es wurden Whisker-verstärkte Keramikeinsätze mit der ISO-Werkzeugbezeichnung RNGN 1907 00T01020 für die Bearbeitbarkeitsversuche verwendet und es wurden runde Schneidwerkzeugeinsätze gewählt, wie sie in der produktionstechnischen Industrie üblich sind. Es wurde ein Taguchi-Design für die Experimente angewendet, um die optimalen Schnittparameter zu bestimmen, wobei die Effekte der Schnittgeschwindigkeit und Vorschubrate auf die Oberflächenqualität analysiert wurden. Dabei wurden vier Schnittgeschwindigkeiten und drei Vorschubraten während der Drehvorgänge angewendet, um das Regressionsmodell für Ra (durchschnittliche Oberflächenrauheit) in Bezug auf die aktuellen Werte der Parameter aufzustellen. Die Härte der Einsätze wird signifikant von einer höheren Vorschubrate beeinflusst.
