A precise analysis has been made for a method to obtain the profile of a screw thread surface which is cut with a given rotary cutter, especially in the case where a rotary cutter 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 screw thread profile corresponding to the cutter profile, and that, because of the cusp, the interference occurs on the screw thread surface. Secondly, a numerical analysis method is proposed to determine the interference by using a conditional equation of the cusp. Then, experimental manufacturing of given rotary cutters is performed. The theories in this analysis are verified through practical screw thread cutting using these rotary cutters, and by measuring the profiles of these screw threads.
