A precise analysis has been made for a design method in order to obtain the profile of a relief grinding wheel surface for a hob which cuts a given screw rotor surface, especially in the case in which the basic thread profile of the hob is given as a series of dispersive points. Firstly, it is clarified that under certain circumstances a singular point (a cusp) will occur on the surface of the relief grinding wheel corresponding to the basic thread profile of the hob, and that, because of the cusp, the interference phenomenon will occur on the surface of the relief grinding wheel. Secondly, numerical analyses are proposed to determine the interference by using a conditional equation of the cusp as well as to obtain the profile of the relief grinding wheel surface. Then, these analyses are theoretically verified by applying them to the dimensions of a pair of screw rotor hobs.
