Due to the today's increasing demands concerning resource-efficient manufacturing processes, the aspect of material savings becomes more and more important. In comparison with cutting operations, the use of forming processes offers the chance to achieve significant saving effects. In the field of the automotive powertrain, the manufacturing of helical gears by rolling processes is an outstanding example. Based on extensive investigations in the last years, helical gears with tooth height up to 15 mm and with a gearing quality of 9 according to DIN 3962 were realized.
