The invention relates to a method and a device for gear cutting a work wheel (1) by means of gear skiving, wherein a first cutting wheel (2) sitting on a tool spindle (16) and having cutting teeth (11) is rotatably driven about a tool spindle axis (4), and the cutting teeth (11) engage in a machining manner into the work wheel (1) carried by a work piece spindle (15) and rotatably driven about a work piece axis (3) that is at an axis angle of intersection (α) to the tool spindle axis (4), in the event of a forward movement (V) in the extension direction of the teeth (5) of the toothing, wherein in a number of consecutive rough cuts, the tooth spaces (6) between left and right tooth flanks (7, 8) of the teeth (5) of the toothing are deepened via a change in the axial distance of the tool spindle axis (4) and the work piece spindle axis (3), and subsequently in finishing cuts, the left and right tooth flanks (7, 8) are precision machined. According to the invention, in order to improve the tooth flank quality, in a first finishing cut, only the left tooth flank (7) is machined with a chip removal point (14) moving from the top of the tooth (9) to the base of the tooth (10) with the gear skiving movement, and in a second finishing cut, only the right tooth flank (8) is machined with a chip removal point (14) moving from the top of the tooth (9) to the base of the tooth (10) with the gear skiving movement |
