Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Oberflächenverdichtung einer Verzahnung, wobei eine Anzahl einer zu wiederholenden Verdichtungsbewegung eines Formwerkzeuges zum Oberflächenverdichten einer Fläche an der Vorform iterativ berechnet wird. Ein Abbruchkriterium kann beispielsweise das Erreichen einer bestimmten Oberflächendichte sein.
