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 diagonal ratio is changed within the course of the machining of a workpiece.
Claims20
A method for gear manufacturing machining of a workpiece by a diagonal-generating method using a tool, comprising:
- subjecting the workpiece to a gear tooth machining using the tool,
- 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 the first axial feed and the second axial feed are controlled on a basis of a diagonal ratio, where the diagonal ratio is defined as a ratio between the first axial feed and the second axial feed, and
- changing the diagonal ratio within a course of the gear tooth machining of the workpiece.
A tool for gear manufacturing machining of a workpiece by a diagonal-generating method, wherein the tool has at least two regions which are used after one another for machining a same region of the workpiece, the two regions comprising at least one rough machining region and at least one fine machining region, wherein the two regions have different widths, and/or wherein the tool has at least one modified region and one unmodified region which are used after one another for machining different regions of the workpiece, and/or wherein the tool has two modified regions between which an unmodified region is disposed which are used after one another for machining different regions of the workpiece, wherein the two modified regions of the tool are differently modified and have modifications having a different orientation, and/or wherein the tool has a conical basic shape, wherein a conical angle of the tool is larger than 1°, and/or wherein the conical angle of the tool is less than 50°.
A gear manufacturing machine for machining of a workpiece by a diagonal-generating method, in which the workpiece is subjected to gear tooth machining by a generating method, wherein the gear manufacturing machine has an input function and/or a calculation function via which different diagonal ratios and/or a variable diagonal ratio are predefined and/or determined and/or a control function which changes a diagonal ratio within a framework of the machining of a workpiece.
