A continuous generating process in which a cutter resembling a helical gear rotates in sync with the workpiece at a crossed axis angle, so the relative sliding produces the cutting action. It is far faster than shaping for internal gears and splines and can cut close to shoulders, but it needs very rigid, precisely synchronized machines and carefully designed tools.
Power skiving the ring gears takes four minutes a part against twenty on the shaper, if the spindle sync holds.
