Sažetak

The paper presents results of experimental study focused on the analysis of radial and hoop strain distributions and effect of strain-hardening of the surface layers of sheet metal hollow parts produced by multi-pass metal spinning. The thin sheets of 1 mm thickness, steel EN 10025-94 (ISO 630-80), were used for experimental study. The results of the study confirm minimal influence of the anisotropy of material on radial and hoop strain distributions and the relatively significant influence of the material anisotropy on the strain-hardening of the spun part's surface layers. It is found higher strain-hardening in the direction 90° refer to the rolling direction of the sheet compared to the direction 0°.
