| Abstract: | This paper presents a new method in which segmantal arcs of best uniform approximation and tolerance smooth are used to fit a plane curve consisting of listed points. The method possesses the advantages of the smallest fitting error, the least segments when the tolerance value is given, the control-dble smooth between the segments, the function of smooth data, and it can be . directly used to numerical control machining and graphing. It is applicable in Engineering. |
