  • Patent number: 8388281
    Abstract: A face milling cutter method for manufacturing various hypocycloidal bevel gears that is characterized in that the following steps are performed to manufacture a first bevel gear: equipping a universal face milling cutter in a first configuration with a first number of cutter groups that corresponds to a first number of passes. A first bevel gear is then produced in the continuous partial method using the universal face milling cutter in the first configuration. The following steps are performed to manufacture a second bevel gear: equipping the same universal face milling cutter in a second configuration with a second number of cutter groups that corresponds to a second number of passes. The second bevel gear is then produced in the continuous partial method using the universal face milling cutter in the second configuration.
