| Abstract: | A method of setting up curved surface for NC machining is discussed , where the B-spline is employed. It is pointed out that the curved surface composed of B-splines has first-order as well as second order continuity, so that several curved stripes can be pieced together to make up a free curved surface in arbitrary shape. Thus, the modeling difficulty of spatial curved surface for NC machining is overcome,and an authentic theoretical basis is provided for establishment of free spatial curved surface. |
