Abstract: The intelligent precision grinding method of the annular inner and outer spheres is proposed. Its principle is that the spherical center is located on the origin of the coordinate system, and the sphere rotates around y axis. In grinding process, the swing angle of grinding wheel spindle is controlled so that the center line of spindle and the normal of spherical bus grinding point always remain coincident. The size of sphere is detected in real time, the loss of the grinding wheel is automatically compensated, and the whole grinding process is automatically finished. The prototype is developed using the proposed method. The research results show that the proposed method can effectively realize intelligent precision grinding of the annular inner and outer sphere with simple control model.
