forming for the production of helical gears feasible. The vertical axial forming machines possess significantly lower torsional stiffness due to their design, so a completely new ram guide concept had to be developed for these forming machines. Using the numerical opti mization process (FEM-based software Meshparts), the simulated machine deformation under the maximum permissible load was reduced by 70% compared with the reference condition. In combina tion with a high-powered drive and high-precision measuring tech nology, the production of helical gears on vertical axial forming machines can be not only feasible to achieve precise gear tolerances but also a significant expansion of the gear parameters and dimen sions that can be generated.
