| Abstract: | This paper describes the B-SURF system which includes 3-D geometric design and calculation of contour values,3-D graphics transformation and processing,auto-programming for NC drafting and NC machining,etc.The system can perform a lot of functions.It is based on the method of multiple knot nonuniform B-spline,which has a great capacity for modeling.The system applies the informations of the multiple knot to the post-processing,so that it fully reflects the advantage of this method.The system has a generality,and can be used to design and manufacture pilotless aircraft,light plane,automobile or other products with complex curved surfaces |
