英文摘要：

Aiming at error measure,the principle of the separation of error is analyzed on the basis of geometric error model followed by optimized multi- body system kinematics built machine. The modeling and simulation are implemented by MATLAB software. The simulation results is experimented and a comparative analysis of geometric errors of machine tools is given. The results show that the method can solve the high measurement cost and requirements.
