Abstract
The invention relates to a method for gear shaping a toothing (55) with a specified normal pitch (mn), angle of action (α), and optionally a helix angle (β) on a workpiece (50), wherein a shaper cutter (40) moving in stroke cycles with a specified stroke length (h) removes material from the workpiece in multiple working strokes in a rolling machining engagement, thereby forming contact tracks, wherein the contact track on the partial circle in the stroke center runs at an angle (γ) to the flank line (57) at least for a first plurality of strokes, the cotangent of said angle being smaller than or equal to the product of a constant of 40, preferably 33, in particular 25, and a geometry/process factor.
