Abstract: According to the theories of differential geometry and space geometry, this article proposes a mesh post disposal method of the winding trajectory by applying the doffing points on the mould surface aiming in the fiber winding process. First, the spit points are obtained by the same distance between the spit point and its corresponding doffing point, and then, the machine trajectory can be worked out depending on the coordinate difference between the neighboring spit points. Finally, to validate the feasibility of the mesh post disposal method in disposing the trajectories of both gyration mould and nongyration mould, two fiber winding experiments on tee shape and combination shape are carried out. Both winding trajectories are realized well by the NC code programmed according to the mesh post disposal.
