【Abstract】 The new method of real time seperation of the rotary errors of axis system with three sensors synchronously in the same position, which is put forward in this paper, can seperate both of system and random errors during the measuring process and inprove the measurement accuracy several times or more. The process diagram of seperating the system rotary errors is given, and the experiment device features which is developed to verify the correction of experiment method and the conclusion deduced from several types of device are discussed. It also evaluates the uncertainty of the results and analyses the supplying prospect of the seperating method.更多还原
