Abstract
A cutting toolincludes a cutting edge, a rake faceand a flankand is used for cutting a surface of a cylindrical or columnar work W by a skiving process. The cutting toolis configured to satisfy a relational expression:tan(cos β/cos(α−β)×tan(cos())<φ≤90°where 'φ' denotes a rake angle, 'α' denotes an inclination angle of the cutting edgewith respect to the rotation axis A, “β” denotes an angle between a feed direction of the cutting tooland a direction orthogonal to a rotation axis A in a plane view of the cutting tooland the work W, “r” denotes a radius of an outer circumferential surface of the work W before processing, and “r'” denotes the radius of the outer circumferential surface of the work W after processing.
