PROBLEM TO BE SOLVED: To provide a gear cutting tool which is formed by being applied with a new design method of the gear cutting tool.;SOLUTION: Blades 2a of a gear cutting tool 2 are formed so as to correspond to a plurality of blade shape points P21(N) on the basis of the execution of individual processing for deciding one blade shape point P21(N) at the gear cutting tool 2 corresponding to one cut point P1(N) at a tooth side face of a gear 1. The cut point P1(N) in the case that a prescribed directional component Vn1(N) of a speed vector V1(N) by the gear 1 around a center axis X1 of the gear 1 at the cut point P1(N), and a prescribed directional component Vn21(N) of a speed vector V21(N) by the tooth cutting tool 2 around a center axis X2 of the tooth cutting tool 2 at the cut point P1(N) become equal is set as the blade shape point P21(N) of the tooth cutting tool 2.;SELECTED DRAWING: Figure 4B;COPYRIGHT: (C)2018,JPO&INPIT
