The Method of Roundness Profile Precious Measurement Based on High-level Removing Eccentric Error

摘要：

During the process of roundness profile precious measurement, assemble eccentric error is the significant source which effects the measurement precision, this error is caused by the geometrical center of the revolution type workpiece and the rotatory center of rotation spindle is not in coincident, for this problem, after analyzing principle error of the traditional measurement model, this paper bring forward a roundness profile precious measurement method which is based on the high-level removing eccentric error, and set up the measurement models of the quadratic removing eccentric error and quartic removing eccentric error, moreover,the paper also compare the estimated accuracy of the model parameters between the traditional measurement model and the precious measurement model based on high-level removing eccentric error through the computer simulation.so the availability of this method which this paper puts forward is tested, accordingly, the measurement accuracy of the roundness profile can be improved.
