A method for machining the tooth flanks of a face coupling workpiece, wherein the method is a semi-completing single indexing method, in which a tool (100, 200) is used, in which it is either a gear cutting tool, which comprises at least one cutter head having two cutting edges (21.a, 21.i), which are arranged on the at least one cutting head so that they define a positive tip width (s a0) or in which it is a grinding tool in the form of a cup grinding wheel having two grinding surfaces (221.a, 221.i), which define a positive profile width (s a0), wherein the method comprises the following step: A1. executing at least one first relative setting movement, to achieve a first relative setting, wherein as part of the first relative setting movement the execution an exiting movement and a plunging movement is preformed, characterized in that the method also comprises the following steps: A2. finish machining of a first tooth flank (13.2; 13.1) of a tooth gap of the face coupling workpiece using at least one first cutting edge of the two cutting edges (21.a; 21.i) or using a first grinding surface of the two grinding surfaces (221.a; 221.i) of the tool (100, 200) and simultaneously premachining a second tooth flank (13.1; 13.2) of the same tooth gap using the second cutting edge of the two cutting edges (21.a; 21.i) or using the second grinding surface of the two grinding surfaces (221.a; 221.i) in the first relative setting, A3. executing at least one second relative setting movement, to achieve a second relative setting, wherein as part of the second relative setting movement the execution an exiting movement and a plunging movement is preformed, A4. finish machining of the second tooth flank (13.2; 13.1) of the same or a further tooth gap using at least one second cutting edge of the two cutting edges (21.a; 21.i) or using the second grinding surface of the two grinding surfaces (221.a; 221.i) of the tool (100, 200). A1. executing at least one first relative setting movement, to achieve a first relative setting, wherein as part of the first relative setting movement the execution an exiting movement and a plunging movement is preformed, characterized in that the method also comprises the following steps: A2. finish machining of a first tooth flank (13.2; 13.1) of a tooth gap of the face coupling workpiece using at least one first cutting edge of the two cutting edges (21.a; 21.i) or using a first grinding surface of the two grinding surfaces (221.a; 221.i) of the tool (100, 200) and simultaneously premachining a second tooth flank (13.1; 13.2) of the same tooth gap using the second cutting edge of the two cutting edges (21.a; 21.i) or using the second grinding surface of the two grinding surfaces (221.a; 221.i) in the first relative setting, A3. executing at least one second relative setting movement, to achieve a second relative setting, wherein as part of the second relative setting movement the execution an exiting movement and a plunging movement is preformed, A4. finish machining of the second tooth flank (13.2; 13.1) of the same or a further tooth gap using at least one second cutting edge of the two cutting edges (21.a; 21.i) or using the second grinding surface of the two grinding surfaces (221.a; 221.i) of the tool (100, 200). A2. finish machining of a first tooth flank (13.2; 13.1) of a tooth gap of the face coupling workpiece using at least one first cutting edge of the two cutting edges (21.a; 21.i) or using a first grinding surface of the two grinding surfaces (221.a; 221.i) of the tool (100, 200) and simultaneously premachining a second tooth flank (13.1; 13.2) of the same tooth gap using the second cutting edge of the two cutting edges (21.a; 21.i) or using the second grinding surface of the two grinding surfaces (221.a; 221.i) in the first relative setting, A3. executing at least one second relative setting movement, to achieve a second relative setting, wherein as part of the second relative setting movement the execution an exiting movement and a plunging movement is preformed, A4. finish machining of the second tooth flank (13.2; 13.1) of the same or a further tooth gap using at least one second cutting edge of the two cutting edges (21.a; 21.i) or using the second grinding surface of the two grinding surfaces (221.a; 221.i) of the tool (100, 200).
