Kurzbeschreibung (Abstract)

Within this work it was the aim to determine an adapted process strategy to control anisotropic shape deviations of paperboard by incremental forming. Therefore, first the influence of the forming velocity was investigated. It can be stated, that the forming velocity has no influence onto the final part geometry for the investigated range. Following, reference tests with a circular process strategy were conducted to specify the resulting contour of the shaped parts. The resulting contour could be approximated in good accordance as elliptic with its major axis parallel to the machine direction. Thereby, it was determined that the geometrical differences between the machine direction and the cross direction is significantly smaller than expected by the mechanical properties, determined in a uniaxial tensile test. Furthermore, a different spring back behavior in machine and cross direction was determined depended on the force transmission and subsequently on the compression of the gaps between the fibers. In accordance to the elliptical contour after a circular processing, the approach of an elliptical process strategy was investigated with its major axis parallel to the cross direction. It can be stated that circular shaped parts can be manufactured by an adjusted elliptical process strategy.
