  text: <jats:p>Abstract. The incremental flow forming process features a large number
    of process parameter combinations that can be varied from pass to pass or during
    a pass. In the future however, a more efficient utilization of this large number
    of process parameter combinations and a compensation of process disturbances could
    be required. This is due to a rising demand for increasing the part complexity,
    e.g. by graded property structures or a more complex geometry. In this context,
    innovative approaches like closed-loop property control and optimal control are
    advantageous, but require fast process models of flow forming that are not state
    of the art. This paper thus proposes a new modelling approach of multi-pass flow
    forming especially taking the transfer behavior between process parameters and
    wall thickness evolution from pass to pass into focus. A hybrid modelling approach
    is developed that combines knowledge about the incremental process character with
    empirical data regression to a basic analytic relation. The basic relation is
    further extended by a multi-layer neural network to enhance the overall model
    accuracy. This hybrid modelling approach is finally validated using experimental
    data. Thus, it is shown that a suitable model structure was found in context of
    a future closed-loop control or optimal control for multi-pass flow forming.</jats:p>
