Several results were obtained concerning with torque variation and cutting force through this study. They were as follows : - 1) The variation of torque was similar to that of the principal component of cutting force and by analyzing the torque variation the tendency of the cutting force could easily be imagined. 2) The variation of torque caused by changing the work material, shape of cutting tool and the quality of tool was also similar to the cutting force under the same cutting conditions. 3) The tangential force calculated from the torque value was nearly the same as the cutting force in several percent of error. 4) The ratio of maximum torque value to mean torque value increased according as the depth of cut decreased, and its value decreased according as the cutting speed increased. 5) The difference between maximum torque value and minimum one, which was computed in terms of tortional strain, increased according as the depth of cut increased within the area of low cutting speed.}, pages = {287--301}, title = {金属の旋削におけるトルクの変動}, volume = {2}, year = {1968} }
