Abstract
Soft milling bevel gear teeth on multiple similar bevel gears using a universal hobbing tool with a set of bar cutters comprising a plurality of pairs of inner and outer cutting edges, having four machining phases: 1) simultaneous milling machining a first bevel gear's convex inner and concave outer flanks with the pairs; 2) milling finishing pre-machining either the concave outer flanks with the outer cutting edges the convex inner flanks with the inner cutting edges without employing respective other cutting edges; 3) using the same tool with the same set of cutter bars to pre-tooth a second similar bevel gear, including simultaneous milling machining the gear's convex inner and concave outer flanks; 4) milling finishing pre-machining on the second gear either the concave outer flanks with the outer cutting edges or the convex inner flanks with the inner cutting edges without employing respective other cutting edges.
