Abstract

In this study, AA 7075 aluminum alloy has been burnished using different burnishing parameters such as burnishing force, number of passes, feed rate and burnishing speed with a ball burnishing apparatus. Burnishing parameters, which affect the surface hardness, were examined using response surface methodology with rotatable central composite design and analysis of variance. Using the experimental results, a regression model has been developed to predict surface hardness. The statistical analysis showed that, burnishing force and number of passes have the most significant effect on surface hardness. These results, which were obtained from the regression model, are highly consistent with the experiments. The absolute average error between the experimental and predicted values for surface hardness was calculated as 2.79 %. The results of our study show that response surface methodology is a suitable technique that can be efficiently used to predict surface hardness in ball burnishing process.

Kurzfassung

In der diesem Beitrag zugrunde liegenden Studie wurde eine Aluminiumlegierung AA 7075 mit variierenden Parametern, wie der Polierkraft, der Anzahl der Durchgänge, der Vorschubgeschwindigkeit und der Poliergeschwindigkeit, mittels eines Kugelpoliergerätes poliert. Die Polierparameter, die die Oberflächenhärte beeinflussen, wurden mittels der Oberflächenantwortmethodik durch einen rotierbaren zentralen Kompositdesign und durch Varianzanalyse untersucht. Unter Verwendung der experimentellen Ergebnisse wurde ein Regressionsmodell entwickelt, um die Oberflächenhärte vorherzusagen. Die statistische Analyse ergab, dass die Polierkraft und die Anzahl der Durchgänge den größten Effekt auf die Oberfläche ausüben. Diese Ergebnisse, die sich aus dem Regressionsmodell ergaben, sind sehr übereinstimmend mit den experimentellen Ergebnissen. Der durchschnittliche Fehler zwischen experimentellen und vorhergesagten Werten der Oberflächenhärte wurde mit 2,79 % kalkuliert. Somit zeigen die Ergebnisse der Studie, dass die Oberflächenantwortmethodik eine geeignete Technik ist, die effizient zur Vorhersage der Oberflächenhärte im Kugelpolierprozess angewendet werden kann.
