METHOD OF CORRECTING PROCESS TOLERANCE OF GEAR GRINDER

摘要

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;COPYRIGHT: (C)2016,JPO&INPIT
