Abstract:
We have developed the B-SURF 3-D CAD system based on the works of years about computer aided design and manufacturing of aircraft and automobile. The system can perform many functions, including 3-D geometric design and calculation of contour values, 3-D graphic transformation and processing, NC drafting and machining auto-programming, etc. The system takes the method of multiple knot nonuniform B-spline, which has a greater capacity for modeling, as its basis. The system, emphasizing the combination of pre-and post-processing, showed sufficiently the advantage of the method with certain degree of generlity the system can be used for geometric designing and manufacturing of drone, light plane, automobile and other products with complex curved surfaces.
