Abstract: To overcome the brittleness of conventional analytical method of conjugating surface design in intelligent CAD system, the decomposition and reconstitute principle is proposed first for establishing general-purpose design system with high adaptability. Then, design of the profile of form milling cutter for helicoid surface is taken as an example of application of the new principle. Finally, practical software development and callculation hare been made with effection compared with well-known results.
