POWER SKIVING PRESSURE ANGLE CORRECTION WITHOUT TOOL GEOMETRY CHANGE
Cutting blade pressure angle changes or corrections in power skiving cutters (20) can be realized without the need tor a tool geometry change. An axial shift (26) of the blade reference point (24) will shift the existing involute on the blade profiles (22, 23) into a different radial location. An accompanying shift (AR) of the reference involute profile (30) by approximately the same amount and in the same direction will re-establish the relationship between work gear and cutter. The resulting work gear geometry has the same radial location of the slots, with the same slot width and the same tooth thickness but with a changed pressure angle.
