A method for gear manufacturing machining of a workpiece, comprising the steps:
- hobbing machining of the workpiece to generate a gearing geometry of the workpiece, and
- gear skiving of the workpiece,
- wherein the hobbing machining is carried out at an axial cross angle between a hobbing tool and the workpiece in a range of 90°+/−45° and the gear skiving is carried out at an axial cross angle between a skiving tool and the workpiece in a range of +/−45°.
A gear cutting machine comprising a workpiece holder and a tool holder that is travelable via movement axes of the gear cutting machine with respect to the workpiece holder, with the tool holder arranged at a machining head of the gear cutting machine that is travelable over the movement axes of the gear cutting machine, with the gear cutting machine having a control with software for controlling the movement axes of the gear cutting machine, the software comprising instructions for hobbing machining the workpiece to generate a gearing geometry of the workpiece and gear skiving the workpiece, wherein the hobbing machining is carried out at an axial cross angle between a hobbing tool and the workpiece in a range of 90°+/−45° and the gear skiving is carried out at an axial cross angle between a skiving tool and the workpiece in a range of +/−45°.
Software for controlling a gear cutting machine, the gear cutting machine comprising a workpiece holder and a tool holder that is travelable via movement axes of the gear cutting machine with respect to the workpiece holder, with the tool holder arranged at a machining head of the gear cutting machine that is travelable over the movement axes of the gear cutting machine, the software having a function for carrying out hobbing machining of a workpiece to generate a gearing geometry of the workpiece, and gear manufacturing machining of the workpiece by gear skiving, the software comprising instructions for hobbing machining the workpiece to generate a gearing geometry of the workpiece and gear skiving the workpiece, wherein the hobbing machining is carried out at an axial cross angle between a hobbing tool and the workpiece in a range of 90°+/−45° and the gear skiving is carried out at an axial cross angle between a skiving tool and the workpiece in a range of +/−45°.
A method for gear manufacturing machining of a workpiece, comprising the steps:
- hobbing machining of the workpiece to generate a gearing geometry of the workpiece, and
- gear skiving of the workpiece,
- wherein the hobbing machining takes place at a first axial cross angle between a hobbing tool and the workpiece and the gear skiving takes place at a second axial cross angle between the tool and the workpiece, with a difference between the first and second axial cross angles amounting to more than 45° and less than 135°.
