Paper Abstract

Measurement points are obtained using a CMM. Lyite rule is used to optimize the data. The algebra relationship between independent parameters and Cartesian coordinate system is built using parametric equations of Archimedes helicoid surface and the error equations about the parameters are constructed. The parameters are acquired use least square method. Experimental results show that the proposed method can be used to make the values of parameters close to the theoretical values, and so, it can be used to do other kinds of parameters fitting of helicoid surface.
