Abstract
The current manufacturing trend mainly involves automation precisely to offer better productivity and improved quality. In this context, on-line monitoring of tools becomes essential. Acoustic emission is the most recognized technique used for condition monitoring of machine tools. Grinding is a material removal and surface generation process employed to shape and finish components made of metals and other materials. The research work deals with machining of CUMITUFF WR-90 alumina ceramics by employing two different grinding wheels made of aluminum oxide and silicon carbide under varying depth of cut. Surface roughness of the machined component and wear of both grinding wheels were analyzed using acoustic emission technique. For a constant depth, the quality of machining has been improved for the material grinded using silicon carbide wheel, which is inferred from low surface roughness value compared to material grinded using aluminum oxide wheel.
Kurzfassung
Der gegenwärtige Trend in der Produktion bringt eine präzise Automatisierung mit sich, um eine höhere Produktivität und verbesserte Qualität zu realisieren. In diesem Zusammenhang wird die On-line-Überwachung der Werkzeuge essentiell. Die akustische Emission ist die am häufigsten angewandte Technik für das Monitoring der Bedingungen für die Maschinenwerkzeuge. Schleifen ist ein Materialabtrags- und Oberflächengenerierungsprozess, der angewandt wird, um Komponenten aus Metallen und anderen Werkstoffen zu formen und fertig zu stellen. Die diesem Beitrag zugrundeliegende Forschungsarbeit behandelt die maschinelle Schleifbearbeitung von CUMITUFF WR-90 Aluminium-Keramiken, wobei zwei verschiedene Schleifräder aus Aluminiumoxid und Silikoncarbid bei variierender Schnitttiefe zum Einsatz kommen. Die Oberflächenrauheit der produzierten Komponente und der Verschleiß der beiden Schleifräder wurden mittels der akustischen Emissionstechnik analysiert. Für eine konstante Tiefe wurde die Qualität der maschinellen Bearbeitung für den Werkstoff, die mit dem Silikoncarbidrad geschliffen wurde, verbessert, was aus dem niedrigen Wert der Oberflächenrauheit im Vergleich zum Werkstoff, der mit Aluminiumoxidrad geschliffen wurde, abgeleitet werden konnte.
