The hourglass-shaped worm wheel is often cut by a fly tool, especially in the case of small production or of large size. The previous report has taken a NC technique into the fly tool method, and the tool is controlled to trace the theoretical wheel tooth surface. With this method, several traces of the cutter are needed to envelop a theoretical surface, and this results in low productivity. In this paper, the NC fly tool method is combined with conventional technique such as the tool edge profile and the cutter position selectings almost suitable to the wheel tooth surface. In this method, an edged cutter traces the wheel tooth surface one time only. The tooth surface profile errors are investigated in the case of the Lorenz method, the NC Lorenz method and the tilted axis NC fly tool method. The latter method has the potential to reduce profile errors by several percent of those of the first two method.
