Feature recognition is the key technology in establishing auto body panel CAPP system. For regular parts, it has made great achievements in features recognition, which has laid a foundation for feature recognition for complex shape parts, such as auto body panels. This paper has classified holes feature into two-dimensional holes, three-dimensional holes and special holes according to its forming and function properties, and established process expression mode of holes feature on account of the requirement of CAPP system. Algorithms have been developed for holes feature recognition based on recognition rules making use of geometric features of holes’ boundary in UG software, two-dimensional holes and three-dimensional holes can be automatically distinguished, circle holes and non circle holes can also be differentiated automatically, further more, the algorithms can give radius of circle hole and minimum radius of curvature of shaped hole’ boundaries.
