PURPOSE: To provide a tooth profile working method with combination of hob cutting and gear grinding, which can accurately position a formed grinding wheel and which can remarkably reduce the working time of gear grinding. CONSTITUTION: A hob 3 having the pressure angleθ1 smaller than that of the desired tooth profile 6 and a formed grinding wheel 5 having the same tooth profile as the desired tooth profile are provided, and the hob is used for hob cutting that a finishing stock h2 is left, and the formed grinding wheel 5 is positioned so that a tooth flank of the grinding wheel contacts with the tip part C of a working tooth profile, to which hob cutting is performed, and the formed grinding wheel is used for gear grinding of the desired tooth profile.
