【Abstract】 The fundamental and the method of identifying the error parameters and measuring the errorsof the NC machine tools has been introduced in this paper. On the basics of the study work in and abroad focuson the problem in the field, some valuable and creative research work has been done in this paper. A newmethod of identifying the geometric error parameters is developed in this paper. According to the error measuring method proposed by this paper, a lot of measurement work has been done to obtain twenty-one terms geometric error parameters by using the error identification software of the new method.更多还原
