PURPOSE: To provide a retraction quantity regulation method which always holds the retraction quantity at its optimum value in the retraction grinding method for the internal face of a cylindrical work. CONSTITUTION: In a retraction grinding method for returning a grinding wheel once in the notching counterdirection in shifting from rough grinding to a finishing griding, deflection quantities of a grinding wheel axis in the rough grinding and the finishing grinding of a preceding work respectively are always monitored, difference (R) between the deflection quantityδR in completion of the rough griding and the deflection quantityδF in completion of finishing griding is calculated from R=G-(S2 -S1 ), and the value of the (R) is set to the retraction quantity of the grinding of the next work.
