Abstract
A gear-shaped tool (30) having stock removing surfaces (38) is rotated together with a bevel or hypoid work gear (32) in accordance with their respective number of teeth, and the gear-shaped tool 30 is also moved relative to the work gear (32) in the manner of a theoretical generating gear (46) rolling through mesh with the work gear (32) for generating desired tooth surfaces (40) in the work gear (32). Generating motions of between the gear-shaped tool (30) and work gear (32) may be controlled independently of indexing motions of the gear-shaped tool (30) and work gear (32) to improve performance of a gear finishing operation.
