This paper theoretically and technically analyzes the makeup machining of curved surface, and discusses the generating algorithm for cutter track of makeup machining of contour.
In FCDS. a model picked from the model bank is taken as the foundation for generating a contour surface, which makes the further design of the surface have some warranties in hydrodynamics.
