Fermented in 1950's and originated in 1960's, EST(Error Separation Techniques) have been made great advances along with the rapid development of computing techniques,microcomputer and sensing transmitting techniques. Up to now,dozens of EST have been developed domestically and overseas which are aimed at different objects and have their distinct skills. The pity is that they are not unified, and this condition presents an obstacle to fasten the tenor of developing new EST methods. This paper reviews these EST methods and unifies different EST methods with an unified theory of multi-dimension error separation technique, and presents the uniform equation of 1-D and multi-dimension EST which are based on two mapping matrices,i.e.mapping matrix representing form error of workpiece and mapping matrix representing error motion of operating parts of machine or measuring apparatus. Several criteria are put forward according to the unified theory. And the essence of inverse filteration of EST is discussed according to the unified error separation theory.
