| Abstract: | In this paper,we sum up four methods of planar curve fitting of a biarc,constant-ly used in engineering,and introduce the properties of each one.Specially,the method of equalangle of rotational tangent of two arcs is discussed in detail.Finally,a practical method offunction curve fitting of a biarc according to the command of approximating accurate is given.[ |
