Abstract
A power skiving method wherein three-dimensional cutter rotations relative to gear workpiece tooth flank surfaces are carried out so as to reposition the cutter relative to a gear workpiece so as to achieve a decrease and/or an increase in the pressure angle of the tooth flank surfaces. The method can be applied independently to left and right flank surfaces of a tooth slot or the rotations may be superimposed on one another to realize pressure angle corrections on both tooth flanks of a tooth slot.
