Abstract
This study has focused on the Taguchi-based multi-response optimization of the pocket milling process for an optimal parametric combination to yield minimum surface roughness within a minimum machining time using a combination of Grey relational analysis (GRA) and the Taguchi method on the CNC process of DIN 1.0038 medium carbon steel. Sixteen experimental runs based on an orthogonal array of the Taguchi method were performed to derive multi-objective functions to be optimized within the experimental range. The objective functions have been selected in relation to parameters of the pocket milling process, i. e., surface roughness and machining time. The Taguchi approach was followed by Grey relational analysis to solve the multi-response optimization problem. The significance of these factors on overall quality characteristics of the pocket milling process has also been evaluated quantitatively by a variance analysis method (ANOVA). Optimal results have been verified by validation experiments to calculate the effectiveness of the method. The application of this method showed that proper selection of the milling parameters produces better surface roughness within the minimum machining time.
Kurzfassung
Die diesem Beitrag zugrunde liegende Studie ist auf die Taguchi-basierte Optimierung der Bearbeitungsparameter des Taschenfräsprozesses fokussiert, um eine minimale Oberflächenrauheit innerhalb einer minimalen Bearbeitungszeit zu erreichen, wobei eine Kombination aus der Grey-Relationsanalyse (GRA) und des Taguchi-Verfahrens auf den CNC-Prozess eines Stahls DIN 1.0038 mit mittlerem Kohlenstoffgehalt angewendet wurde. Hierzu wurden sechzehn experimentelle Bearbeitungsvorgänge basierend auf einem orthogonalem Array der Taguchi-Methode ausgeführt, um Multi-Zielfunktionen abzuleiten, die innerhalb des experimentellen Rahmens optimiert werden sollten. Die Zielfunktionen wurden hinsichtlich der Parameter des Taschenfräsprozesses, nämlich der Oberflächenrauheit und der Bearbeitungszeit, ausgewählt. Nach dem Taguchi-basierten Ansatz folgte eine Grey-Relationsanalyse, um die Mehrfachantworten optimal zu lösen. Der Einflußgrad der Faktoren auf die Gesamtqualität des Taschenfräsprozesses wurde außerdem quantitativ mittels der Varianzanalyse (ANOVA) bestimmt. Die optimalen Ergebnisse wurden mit Hilfe von Validierungsexperimenten verifiziert, um die Effektivität der Methode zu ermitteln. Die Anwendung dieser Methode hat gezeigt, dass eine geeignete Auswahl der Fräsparameter zu einer verbesserten Oberflächenrauheit innerhalb einer minimalen Bearbeitungszeit führt.
