Relief grinding for involute helical pinion cutters with no profile error is realized by through grinding with a trapezoid-like grinding wheel. As a calculation example, an involute helical pinion cutter with semi-topping and protuberance cutting edges is used. First, a method for calculating the grinding wheel profile to finish the tooth flanks of the pinion cutter with the exact cutting edges is proposed. Next, the profile errors of cutting edges after regrinding are calculated and evaluated by means of the tooth profile of the work gear being shaped by the reground pinion cutter. As the results, it was found that the profile errors and the changes in shapes of the semi-topping and protuberance cutting edges after regrinding are very small. Finally, the usefulness of the proposed methods was confirmed through the grinding tests of the pinion cutter.
