Unanimous Approximation and Smooth Tolerance of Circular Arc Fit for Planar Range of Points and Their Application |
| |
| Abstract: | This article introduces least square method of unanimous approximation and smooth tolerance of segmented circular arc fit for planar range of Points. This method features Simple andpractical operation and irnplementation, dually unanimous approximation of circular arc, Smooth and Controllable tolerance for the Points of connection,besides,it features minimun numbers of segmented circular arcs when allowable fit error is not greater than predetermined Value. This method can directly be used in engineering operation Such as CN Controlled machining and drawing etc. The practical Computing example Shows that above—mentioned method has engineering Significance. |
