Abstract
The present disclosure relates to a method for the gear manufacturing machining of a workpiece by a diagonal-generating method, in which the workpiece is subjected to gear tooth machining by the rolling off of a tool, wherein an axial feed of the tool takes place during the machining with a diagonal ratio given by the ratio between the axial feed of the tool and the axial feed of the workpiece. According to the present disclosure, the tool has a conical basic shape.
Claims19
A method for gear manufacturing machining of a workpiece by a diagonal generating grinding method comprising:
- subjecting the workpiece to a gear tooth machining using a tool, the tool being a grinding worm having a conical basic shape;
- and
- feeding the tool relative to the workpiece with a first axial feed in a direction of a rotational axis of the tool and with a second axial feed in a direction of a rotational axis of the workpiece during the gear tooth machining,
- wherein a distance between the rotational axis of the tool and the rotational axis of the workpiece is changed during the gear tooth machining by superposing the first axial feed with a feed motion of the tool to the workpiece depending at least on a conical angle of the conical basic shape of the tool.
A gear manufacturing machine for machining of a workpiece by a diagonal generating grinding method, wherein the gear manufacturing machine has a tool, the tool being a grinding worm having a conical basic shape and a control function configured to control NC axes of the gear manufacturing machine such that the machine performs a method comprising:
- subjecting the workpiece to a gear tooth machining using the tool;
- and
- feeding the tool relative to the workpiece with a first axial feed in a direction of a rotational axis of the tool and with a second axial feed in a direction of a rotational axis of the workpiece during the gear tooth machining,
- wherein a distance between the rotational axis of the tool and the rotational axis of the workpiece is changed during the gear tooth machining by superposing the first axial feed with a feed motion of the tool to the workpiece depending at least on a conical angle of the conical basic shape of the tool.
