Abstract:
A method for profiling a spiral of a cylindrical rotating grinding worm for diagonal hob grinding using a rotating disk-shaped profiling tool, comprising:performing at least one of an advancing movement of the rotating disk-shaped profiling tool along the spiral of the rotating grinding worm and an advancing movement of the rotating grinding worm along the rotating disk-shaped profiling tool,engaging the disk-shaped profiling tool with the grinding worm over the entire depth of the spiral during a stroke in a direction of one of said advancing movement, andcompleting, within one segment of one of said advancing movement, an additional movement comprising a rotating movement of said disk-shaped profiling tool around a first axis of rotation (F) perpendicular to an axis of rotation (E) of said disk-shaped profiling tool,wherein the magnitude of the rotating movement completed during said one segment of one of said advancing movement depends on a position of the profiling tool relative to the spiral of the grinding worm, and,wherein said method for profiling forms faces of the spiral of the grinding worm having at least one of a pressure angle that diverges from a nominal pressure angle and a pressure angle that changes constantly along segments of the width of the grinding worm.
