Abstract:
1. Method for the machining of gear teeth ( 2 ) whose tooth flanks deviate from their specified geometry by a machining allowance, wherein the machining allowance is removed through an infeed of at least two infeed steps (j), each of which is followed by a machining pass with a profiling tool ( 0 ) that rotates about a tool axis (Y), wherein for this operation the profiling tool ( 0 ) —after it has been set to a position relative to the gear wheel ( 2 ) that depends on the angle (A) at which the plane of rotation of the tool ( 0 ) which is orthogonal to the tool axis (Y) is tilted against the axis (Z) of the gear wheel ( 2 ) —is brought into engagement with the gear teeth, wherein after each infeed step the material within the resultant engagement area of the tool is removed, wherein after the last infeed step (n) with a tilt angle setting (A n =A 0 ) of the profiling tool ( 0 ) that is determined by the design angle (A 0 ) of the latter, the area of tool engagement extends over the entire flank height, so that the next machining pass will remove the amount of material required to attain the specified geometry, characterized in that in at least one infeed step (k) which precedes the last infeed step (n), the profiling tool (
