scope:

Full CNC bevel generators achieve the relative position between the tool and work with simple mechanisms and electronic controls. As a result, the gearengineer has newfreedoms for the control of gear tooth shapes and contact characteristics. This paper defmesthe flared cup Formate gear grindingprocess and the motions that can be applied to the process. Surface comparisoncharts and toothcontact analysisare usedto demonstrate the effects of the freedoms. Comparisons of jobs designed with and without the motionsare included,
