Firstly, the shape of the characteristic curve between the surface of revolution of the whirling tool and the helicoidal surface generated is made clear. Then it is clarified that the involute helicoidal surface is generated and no interference phenomenon occurs in this screw-thread cutting. Secondly, a method is presented to calculate each dimension of the tool and the screw thread of which values are essential for obtaining practical screw threads. Thirdly, a calculation procedure is set up for the sectional shape of the screw thread to be generated. Finally, the theories in this analysis are verified by practical screw thread cutting with the thread whirling attachment for numerical example.}, pages = {41--52}, title = {旋回ねじ切り装置によるねじの軸平行切削}, volume = {18}, year = {1988} }
