In grinding the helical cutting face of a gear hob, the cone-shaped surface of a grinding wheel is widely used. It has been clarified that the grinding wheel surface should be convex to produce the correctly helical cutting face of a gear hob. The rigorous equation and the approximate formula to calculate the profile of the grinding wheel have already been obtained by one of the authors. But no precise analysis has been made on the problem of interference of the surface of a grinding wheel with the helical cutting face of a gear hob. In this paper, the process of interference is firstly analyzed by the characteristic curve between the helical cutting face of a gear hob and the surface of a grinding wheel. Secondly is shown the method to calculate the critical cutter pressure angle over which the interference can be eliminated. Then the theoretical profiles of the cutting face of the hobs are certified to coincide well with the experimental ones. Finally, the approximate formula to calculate the grinding wheel profile is confirmed to be accurate enough by the numerical calculations of both the approximate formula and the rigorous ones.
