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 a feed angle between a dresser rotational axis and a grindstone central axis is shifted before correction, is predicted in order to calculate a correction angle, and after correcting a screw-like grindstone by using a dresser in a posture that the feed angle is corrected only by the calculated correction angle, a workpiece is ground.SELECTED DRAWING: Figure 1
