Einfluss von Maschinenstellgrößen auf die Eigenspannungszustände beim Drehen von Wälzlagerringen

Abstract: Kurzfassung Das Ziel der durchgeführten Arbeiten war, den Einfluss unterschiedlicher Bearbeitungsparameter auf die Eigenspannungen von bearbeiteten Ringen aus GKZ-geglühtem Stahl 100Cr6 zu untersuchen. Die mittleren tangentialen Eigenspannungen als Funktion des Vorschubs f, der Schnitttiefe ap und der Schnittgeschwindigkeit vc wurden nach der Drehbearbeitung mit insgesamt 36 Messungen auf der Ringaußenfläche an unzertrennten Ringen ermittelt. Um Informationen über die Verteilung der Eigenspannun… Show more

“…The outer surface longitudinal turning was conducted with four cuts. For the last cut the cutting parameter feed was changed from f = 0.3 mm to f = 0.1 mm and f = 0.4 mm, respectively, to influence the mean value of the residual stresses [8]. The constant parameters cutting speed and depth of cut were v c = 240 m/min and a p = 0.75 mm.…”

“…In the axially symmetric 2D-simulation the cross-section of the ring (x-z-plane) was selected to generate similar residual stress depth profiles compared to the XRD-measurements from Sölter [8]. The thermal strains in radial and axial direction (x-and z-direction) were set to zero.…”

“…For example, turning changes the residual stress state of a workpiece by superposition of thermal and mechanical loads which typically results in high tensile stresses at the surface and a small area with compressive stresses at a distance of some hundred micrometers under the surface [7]. The residual stress depth profile is mainly influenced by the machining parameters like feed, cutting depth, and cutting velocity [8]. The distribution of the residual stresses in circumferential direction is also influenced by the clamping technique used during turning [9].…”
