Abstract：The coordinate equation of helical gear tooth profile modification and geometric algorithm of form grinding wheel dressing are established,and the section profile of grinding wheel after tooth profile modifi-cation is optimized.The coupling relation between machine position error and tooth profile error is obtained by the numerical simulation.A software for adjusting the precision of form grinding tooth profile is developed,and the forming sand profile and tooth profile precision adjustment parameters corresponding to the helical gear mod-ification are calculated.Through the form grinding experiment of the modified helical gear,the correctness of sand contour trimming and the effectiveness of tooth profile adjustment are verified.
