A precise analysis has been made for a design method to obtain the profile of a rotary cutter which cuts a given screw thread surface, especially in the case where a screw thread profile is given as a series of dispersive points. Firstly, it is clarified that under certain circumstances a singular point (a cusp) will occur on a cutter profile corresponding to the screw thread profile, and that, because of the cusp, the interference phenomenon will occur on the cutter surface. Secondly, a numerical analysis method is proposed to determine the interference by using a conditional equation of the cusp. Then, experimental manufacturing of rotary cutters is performed by applying the design method to the dimensions of a pair of screw rotors. The theories in this analysis are verified through practical screw thread cutting using these rotary cutters.
