Abstract (en)
[origin: EP1792690A1] A method of evaluating the error of the cutting edge profile of a re-sharpening pinion cutter provided by performing relieving grinding by a screw motion along the outer diameter relieving angle of the pinion cutter by using a relieving grinding wheel. First, based on the cross-sectional profile of the relieving grinding wheel and considering the motion of the relieving grinding by the screw motion along the outer relieving angle of the pinion cutter, the cutting edge profile of the pinion cutter after re-sharpening is determined by coordinate transformation. Next, the tooth profile of a pinion having the same outer diameter as that of the re-sharpening pinion cutter and correctly meshing with the tooth profile of an internal gear to be cut is obtained, and the obtained tooth profile is used as an ideal tooth profile of the resharpening pinion cutter. Then, a normal line is drawn from a point on the tooth profile of the obtained re-sharpening pinion cutter to the ideal tooth profile, the length of the leg thereof is obtained, and the obtained length is used as the error of re-sharpening.
