Abstract
The stream finishing process represents an efficient mass finishing process capable in mechanical surface modification. In order to generate a deeper understanding of the cause-effect relationships, normal forces, material removal and surface topography were analyzed and correlated for varied process parameters of disc-shaped AISI 4140 specimens. Local resolution of tangential velocities of the particles and normal forces on the workpiece?s surface were simulated using the discrete element method for defined process parameter configurations and were correlated with experimental results. A deep process understanding is accomplished enabling the process design for efficient surface smoothing and improved residual stress depth distribution.

Abstract
Das Tauchgleitschleifen als eines der produktivsten Gleitschleifverfahren hat sich bei der Endbearbeitung komplexer Bauteile am Markt etabliert und eröffnet zunehmend neue Möglich - keiten in der Auslegung von Fertigungsketten und der Sub - stitution bisheriger Endbearbeitungsprozesse in der Verzahnungsherstellung. Dieser Beitrag behandelt die Optimierung der Oberflächenrauheit und -textur von geradverzahnten Stirnrädern durch Untersuchungen mittels im Zahnrad integrierter Metallstreifen.
