Abstract: A method for designing a cylindrical skiving tool without a geometric relief angle is provided. The method includes: designing a teeth number and a crossed shaft angle of a tool; calculating a barrel-shaped conjugate surface conjugated to a tooth surface of a to-be-machined gear; determining an offset of a rake face of the cylindrical skiving tool from a middle section of the barrel-shaped conjugate surface; designing a helix angle of the tool; designing a rake angle of the tool; calculating an edge profile of the rake face; obtaining design parameters and mounting parameters of the skiving tool; manufacturing the tool according to the design parameters of the tool, and performing skiving on a skiving machine according to the mounting parameters of the tool. The present disclosure provides a skiving method under a spatially-offset conjugate condition, to solve the problems of fast accuracy degradation and short service life.
