<p>The final purpose of the present study is to create design method of taper cutter for internal gear skiving. For this purpose, first of all, the reference cutter geometry on the basis of conjugate pinion was discussed. Conjugate pinions and cutting edges must be calculated according to Variation in center distance. After that, these cutting edges are aligned along with the lead of the conjugate pinion with the minimum center of distance and a taper cutter is constructed. Comparing the conjugate pinion and the taper cutter in a same coordinate system depicted in a figure, the taper cutter was confirmed to be inside of the conjugate pinion. So, this taper cutter does not interfere with the target internal gear in its cutting process. In addition the radial clearance angles of the taper cutter were smaller than those of the conjugate pinion. And chordal tooth thicknesses at some radii of taper cutter were smaller than those of the conjugate pinion. Therefore, it was confirmed that this taper cutter had some clearances on its top land and its tooth flanks between the target internal gear and itself.</p>
