The cutting edges include tooth-top, tooth-bottom and tooth-surface cutting edges, and. The cutter has an inclined cylindrical exterior shape so that its thickness gradually increases from the cutting edges toward the base end. V-shaped grooves are formed on the exterior surface and become shallower from the cutting edge toward the base end. The wedge angle (α1) of the tooth-bottom line from the tooth-bottom cutting edge to the base end is greater than the wedge angle (α2) of the tooth-top cutting edge surface from the tooth-top cutting edges to the base end. The thickness (W1) of the tooth-bottom cutting edge is greater than the thickness (W2) of the tooth-top cutting edge on the base-side end. | ||||||

| 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. | ||||||

| The invention relates to a method for producing a bevel gear wheel, in particular for rudder propellers, the teeth of which have a macro geometry specific to the gear wheels, the teeth of which can be described by flank and profile lines, the flanks of which have a tooth flank micro topography and the bearing surface of which represents the contact region of the inter-meshing teeth.

By means of precise material removal, the micro topography of the tooth flank and thus the bearing surface is optimized firstly in that the material removal is carried out such that the end relief on the tooth flank surface is reduced toward the tooth heel side and the tooth toe side, an area having a greater length and width comes into engagement on the flank and thus an enlarged bearing surface is present, and secondly in that the course of the crown the crown of a tooth flank follows an approximately logarithmic, elliptical and/or an exponential curve shape, which runs through the point of contact, when the ease-off is viewed with no load, in a longitudinal section in the flank sectional surface and/or in a profile section in the profile sectional surface. | ||||||
