A precise analysis has been made of the problem of interference involved in cutting an internal ball screw with the rotary cutter whose axis is parallel to that of the screw. Firstly, the process of interference, which occurs around the minor diameter of the internal ball screw, is discussed. Secondly, a calculation method is shown. This is to calculate the critical diameter of the cutter with which the interference can be eliminated. Then the design drawing and the experimental manufacture of a rotary cutter is made for a numerical example of an internal ball screw. Finally, the theory is verified by practical cutting of an internal ball screw with the rotary cutter.
