The invention discloses a worm finishing process-oriented face gear grinding error model modeling method, which comprises the following steps of: 1, creating a worm tooth surface model in a worm coordinate system, and respectively obtaining an ideal condition and a worm tooth surface model under the condition of considering the geometric error of a worm finishing system; 2, creating a worm tooth surface model in the face gear coordinate system to obtain a worm ideal tooth surface and a worm actual tooth surface in the face gear coordinate system; and step 3, constructing a face gear grinding error model, obtaining a face gear ideal tooth surface and a face gear actual tooth surface in the face gear coordinate system through the worm ideal tooth surface and the worm actual tooth surface in the face gear coordinate system obtained through construction based on the grinding contact relation between the face gear and the worm, and obtaining the face gear grinding error model. And further obtaining a gear grinding
