| 摘要 |
The invention concerns a method of grinding a toothed workpiece in which a central axis of the toothed contour profile is defined, wherein the method encompasses at least two work operations. In a first work operation a grinding zone of a grinding tool whose selection is determined by the grinding process to be performed, which rotates about an axis of rotation and is set up for an infeed in the direction of the shortest distance between said central axis and the rotation axis, is brought into grinding engagement with a tooth flank of the workpiece. In a later, second work operation, the tooth flank is brought into grinding engagement with a grinding zone of a grinding tool whose selection is determined by the grinding process to be performed and which is advanced in the infeed direction of the first operation. The grinding zone that is active in the first work operation is dressed in a first dressing operation with a dressing tool, and the grinding zone that is active in the second work operation is dressed in a second dressing operation with a dressing tool, wherein in the first dressing operation a first dressing tool zone is brought into dressing engagement with the grinding zone that is to be dressed, and in the second dressing operation a second dressing tool zone which is spatially separate from the first dressing tool zone is brought into dressing engagement with the grinding zone that is to be dressed. |

1. Method of grinding a tooth-profiled workpiece (2) having a central axis (Z) of the toothed profile, said method comprising at least two work operations, wherein in a first work operation a grinding zone (10L, 10R) of a grinding tool (0) whose selection is determined by the grinding process to be performed, which rotates about an axis of rotation (y) and is set up for an infeed in the direction (X) of the shortest distance between said central axis (Z) and the rotary axis (Y), is brought into grinding engagement with a tooth flank (20L, 20R) of the workpiece (2), and wherein in a later, second work operation the tooth flank (20L, 20R) is brought into grinding engagement with a grinding zone (10L, 10R) of a grinding tool (0) whose selection is determined by the grinding process to be performed and which is advanced in the infeed direction of the first work operation, wherein the grinding zone (10L, 10R) that is active in the first work operation is dressed in a first dressing operation with a dressing tool (4, 3) and the grinding zone that is active in the second work operation is dressed in a second dressing operation with a dressing tool (4, 3),
characterized in that in the first dressing operation a first dressing tool zone (4a, 3a) is brought into dressing engagement with the grinding zone (10L, 10R) that is to be dressed, and in the second dressing operation a second dressing tool zone (4b, 3b) which is spatially separate from the first dressing tool zone (4a, 3a) is brought into dressing engagement with the grinding zone (10L, 10R) that is to be dressed. |
