Compound surface modeling is widely used for die cavities and punches. A compound surface is defined in 3-D space by specifying the topological relationship of several analytic surface elements and a sculptured surface. A constructive solid geometry scheme is employed to model the analytic compound surface. the desired compound surface can be accomplished by specifying topological relationships in terms of boolean relations between primitives and the sculptured surfaces. Additionally, a method is presented for checking and avoiding the tool interference occurred in machining the compound surface. Using this method the interference of concave, convex, and side region can be checked easily and avoided rapidly.
