PROBLEM TO BE SOLVED: To correct a pressure angle of a workpiece by using a simple method without correcting a shape of a dresser.SOLUTION: An error of a pressure angle of a workpiece tooth surface is detected, and a pressure angle amount to be corrected, when an angle between a vertical axis of a work table and a grindstone central axis viewed from an X direction is shifted from the time of ordinary grinding, is predicted, and then a correction angle is calculated in accordance with the detected error of the pressure angle, and a screw-like grindstone is rotated in a direction A only by the calculated correction angle, and a workpiece is ground by using the screw-like grindstone in this corrected posture.SELECTED DRAWING: Figure 1 【課題】ドレッサの形状を修正することなく、簡単な方法でワークの圧力角を修正できるようにすることにある。【解決手段】ワークの歯面の圧力角の誤差を検出し、Ｘ方向から見たワークテーブルの垂直軸と砥石中心軸との間の角度を通常研削時からずらした場合に修正される圧力角の量を予測し、検出された圧力角の誤差に合わせて修正角度を計算し、計算された修正角度だけネジ状砥石をＡ方向に回転させ、この修正された姿勢でネジ状砥石によってワークを研削する。【選択図】図１
