摘要： The invention relates to a method for producing a removal of material on a tooth end edge of a workpiece toothing with a rotationally driven chamfering tool in a machining operation brought about by controlled axial machine movements between the chamfering tool and the likewise rotationally driven workpiece toothing, wherein material is removed with a geometrically undefined cutting edge and the removal takes place in a coordinated action between a profiling, in particular, an alterable profiling, of the chamfering tool and a machine control used for the machining operation, performed in dependence on predetermined parameters that are characteristic of the removal of material to be produced.

摘要： A method and a device for gear cutting a work wheel includes a cutting wheel with cutting teeth, which is rotatably driven on a tool spindle about a tool spindle axis. The cutting teeth engage into the work wheel, which is rotatably driven on a workpiece spindle about a workpiece axis that intersects the tool spindle axis. In rough cuts, tooth spaces between left and right tooth flanks of teeth of the toothing are deepened via a change in axial distance of the tool spindle axis and the workpiece axis. In a first finishing cut, only the left tooth flank is precision machined with a chip removal point moving from top to base of the tooth with gear skiving movement. In a second finishing cut, only the right tooth flank is precision machined with a chip removal point moving from top to base of the tooth with gear skiving movement.

摘要： A clearance angle, of a blade-like tool or tool tooth of a tool for hob peeling workpieces is determined by defining the rake face contour of the tool and calculating the progression of path movement of the rake face during chip-breaking hob peeling, taking into account a pre-determinable transmission ratio between the tool and the workpiece determined by the respective number of teeth, and the desired tooth cross-section contour of the tool, and determining a tangential speed for points of the cutting edge of the tool during chip-breaking, wherein hob peeling is determined in the form of vectors that are displayed graphically as bundles for each point on the cutting-edge and a closed envelope surface is determined, which plus a desired clearance angle is selected as the shape for the flank face contour of the tool or of the flank face of the tool tooth. A tool is also provided.

摘要： 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.

摘要： Provided are: a screw-shaped grindstone for grinding gears that has a simple configuration and is capable of grinding gears with high precision; and a method for grinding gears. The screw-shaped grindstone (20) for grinding gears, which grinds a workpiece (W1) by rotating while meshing with the workpiece (W1), comprises a screw-shaped grindstone (21) that grinds the workpiece (W1), and a screw-shaped grindstone (22) that is linked to the screw-shaped grindstone (21) on the same axis, and grinds the workpiece (W1), which has been ground by the screw-shaped grindstone (21). A plurality of grinding ranges (L1, L2) that are sectioned at prescribed lengths in the width direction of the grindstone are established with respect to the screw-shaped grindstones (21, 22), and each grinding range (L1, L2) of the screw-shaped grindstones (21, 22) serves as the range of use per workpiece (W1).
