Patent ID: 8882414

Claim:
A method of milling a bevel gear tooth system, comprising: providing a cutter head comprising a plurality of pairs of inner cutting edges and outer cutting edges, wherein the inner cutting edges define a smaller fly circle radius than the outer cutting edges; clamping said cutter head in a gear cutting machine; providing a bevel gear workpiece; clamping the bevel gear workpiece in the gear cutting machine; performing a first continuous metal-cutting machining of the bevel gear workpiece by continuous milling using said cutter head mounted in the gear cutting machine in a first machine setting, whereby convex inner flanks are machined on the bevel gear workpiece by the inner cutting edges; and after performing the first continuous metal-cutting machining, performing a second continuous metal-cutting machining of the bevel gear workpiece by continuous milling using said cutter head mounted in the gear cutting machine in a second machine setting that is different from the first machining setting, whereby concave outer flanks are machined on the bevel gear workpiece by the outer cutting edges, wherein, during the machining steps, movements of the cutter head and bevel gear workpiece are coupled.
