Abstract:
1. A method for chamfering and/or deburring edges on the teeth of a bevel gear on a bevel gear cutting machine having at least five numerically controllable axes, in which the bevel gear is mounted so it is rotatable on a workpiece spindle having a workpiece spindle axis and a cutter head having multiple bar blades is mounted so it is rotatable around a tool spindle axis, wherein the method comprises the following steps, which are executed following gear cutting machining of the bevel gear: adjusting the workpiece spindle axis and/or tool spindle axis in order to enlarge the relative inclination between the workpiece spindle and the cutter head, by setting a larger angle which deviates by an angular differential of between 10° to 60° from the angle which was used when milling the same bevel gear; and executing a coordinated rotation of the workpiece spindle around the workpiece spindle axis and the cutter head around the tool spindle axis, in order to allow the bar blades of the cutter head to engage one after another in tooth intermediate spaces of neighboring teeth of the bevel gear and execute a chamfering or deburring motion in relation to edges of the bevel gear there; wherein at least two of the at least five numerically controllable axes have their motions coupled in order to achieve the coordinated rotation; and wherein the gear cutting machining of the bevel gear and the chamfering and/or deburring of edges are executed on the teeth of the bevel gear using the same cutter head.
