Der konstruktive Aufbau von Spitzenlosschleifmaschinen erschwert die Implementierung von Sensorik zur Prozessüberwachung. Daher wird ein Sensorsystem zur Schwingungsmessung beim Spitzenlosschleifen vorgestellt, das auch zur Nachrüstung von Bestandsmaschinen geeignet ist. Die erfassten Daten während spitzenlosen Einstechschleifversuchen korrelierten in guter Näherung mit schleifscheibenverschleißbedingten Änderungen der Werkstückeigenschaften.   The design of centerless grinding machines makes it difficult to apply suitable sensors for process monitoring. This paper presents a sensor system for vibration monitoring during centerless grinding, which can also be used for retrofitting existing machines. The data recorded during centerless plunge grinding correlated in a good aproximation with changes in the workpiece properties related to grinding wheel wear.

Work Interaction

Grinding of ceramics is often treated as coarse grinding dominated by brittle fracture or fine grinding, at very low removal rates, dominated by plastic deformation. Through a set of experimental observations and analysis, it is shown that in grinding of ceramics the abrasive/work interaction can be treated similar to well known chip formation models. Such an approach permits the coexistence of ductile deformation and brittle fracture during the grinding of ceramics. When the grinding process is managed such that the brittle fracture is minimized, while maximizing the plastic deformation optimum results are achieved. In this regard it is conceivable to design ceramic grinding cycles, where the rough grinding cycle focuses on surface generation to achieve high material removal rate and productivity while minimizing brittle fracture and the finish grinding cycle focuses on surface generation which maximizes plastic deformation while still minimizing brittle fracture. While the above accounts for only one of four interactions in the grinding zone (viz) abrasive/work interaction, it is also necessary to address the other three interactions (viz) chip/bond, chip/work and bond/work interactions. The later considerations for ceramics grinding are identical to well established practices in metal grinding. When such grinding cycle optimization is carried out taking simultaneously into account the aspects of machine tool, grinding wheel, work material and operational factors, significant progress can be made in the grinding of ceramics. The results obtained through such systems approach are also described in this paper.

This study has developed a new kind of high performance monolayer brazed diamond tool for ceramic grinding. The grit size of the diamond brazed in the grinding wheel surface is 300m, which has never been reported in diamond tools for ceramic precision machining. The experiment has achieved wonderful surface finish of Zirconia workpiece. This does owe to the designed and precision conditioned topography of the new developed grinding wheel. The topography of the grinding wheel before and after dressing has been measured by means of laser triangulation method. Then the Zirconia workpiece has been ground. The obtained Ra value decreases with no spark grinding times and the minimum Ra of the ground surface is 0.11m. The study proved that the brazed large grit diamond tools would realize high efficiency and precision grinding, namely, high performance of ceramic grinding.
