Abstract
A method of generating machining of a gear-shaped workpiece (23), in particular by continuous generating grinding, in which the gear-shaped workpiece rotates about a workpiece axis (C) while in generating mesh with a generating machining tool. During machining, the gear-shaped workpiece performs an oscillating movement which is superimposed on the rotation of the gear-shaped workpiece. Also disclosed are a clamping device (22) configured to perform the method, and a system comprising such a clamping device and a control device (50). Finally, a generating machining machine comprising a clamping device of the mentioned type is also disclosed.
Claims24
A method for machining a gear-shaped workpiece by a generating machining process in which the gear-shaped workpiece rotates about a workpiece axis while it is in generating mesh with a generating machining tool, in particular with a worm shape profiled grinding tool, characterized in that the gear-shaped workpiece is specifically excited during machining to carry out an oscillating movement which is superimposed on the rotation of the gear-shaped workpiece.
A clamping device for clamping a gear-shaped workpiece on a workpiece spindle of a generating machining machine, in order to drive the gear-shaped workpiece to rotate about a workpiece axis,
- wherein the clamping device has a clamping portion in which the clamping device is in contact with the gear-shaped workpiece,
- characterized in that the clamping device comprises a vibration generator for generating a vibration of the clamping portion with the gear-shaped workpiece being in contact therewith.
