Method for deburring bevel gears and CNC gear-cutting machine having corresponding software for deburring

A CNC gear-cutting machine comprising:

• a workpiece spindle configured to mount and rotationally drive a workpiece,
• at least six axes, and
• a software module,
• wherein the CNC gear-cutting machine is configured to execute the following steps:
• deburring in a continuous method a bevel gear defining a bevel gear heel, a bevel gear toe, at least one tooth and at least one tooth gap defining at least one tooth edge, by using a deburring tool including at least one cutting edge, the deburring step comprising:
• rotationally driving the deburring tool around a deburring spindle axis,
• rotationally driving the bevel gear around a workpiece spindle axis in a coupled manner with said rotationally driving the deburring tool using an inverse coupling transmission ratio,
• executing a relative flight movement of the at least one cutting edge relative to the bevel gear, wherein the relative flight movement is defined by a hypocycloid, and
• removing at least one burr located at or near one or more of the bevel gear heel and the bevel gear toe from at least one of the at least one tooth edge by cuttingly contacting the at least one cutting edge with the at least one of the at least one tooth edge.
