The invention relates to a method for modifying the geometry of gear wheel tooth flanks using a tool having a toothing that engages with the gear wheel (ZR) during precision machining. In this case, a profile that varies over the width (Bw) of the tool (1) is produced on the tool (1) in that, during a dressing operation, a dressing wheel (3) is moved along the tooth flank (5) of the tooth (6) to be dressed. The width of the teeth (16) of the dressing wheel (3) is much smaller than the width (Bw) of the tool (1).

After dressing, the precision machining of the gear wheel (ZR) using the tool (1) takes place. Since, in the process, the dressing wheel (3) is moved with a changing pitch and a changing crossed axes angle (Σ) with respect to the tool (1), the modification of the tooth flank geometry can be transferred to the tool (1).
