Investigation of interaction between forming processes and rotor geometries of screw machines

In the course of the minimization of production costs in the automotive field of screw machines, like superchargers, the issue of further manufacturing methods applies to the entire machine and especially to the complicated close-tolerance geometry of the screw rotors. Manufacturing must meet high precision standards in the case of the complex geometry of the rotors, because tolerance deviations during manufacture will significantly influence the energy efficiency and also the operating reliability.
