N2 - A key factor influencing the economic efficiency of a forging process is time. To be competitive, organisational, administrative aspects, and decisions on content design must be clarified in the shortest possible time. The development of a forging process includes the creation of a so-called forging sequence plan, in which an initial body (semi-finished product) is successively brought into a target shape. As a rule, the stages are designed iteratively by calculating backwards to the semi-finished product (cylinder, cuboid, etc.). Therefore, automation solutions offer great potential for significantly reducing the iterative effort. In a multi-stage forging sequence plan, the first stage after the semi-finished product is called the preform. The preform has a significant influence on the amount of flash, number of stages and various forming parameters (e. g. forming load). Suitably designed preforms can therefore lead to a reduction in the number of stages. Rolling processes, for example, are suitable for creating preforms. The method presented here shows how mass-optimized preforms can be designed automatically for cross-wedge and non-circular rolling processes. This approach offers the advantage that forming processes do not have to be designed exclusively by backward iteration. Parameters or machine limits then can be used to calculate the following intermediate forms, thereby reducing the number of iterations needed.
