Referring to the disadvantage of permutation intercomparision method, such as complex operation and heavy workload in mutual check of two circle dividing devices, permutation ruled angle method is used to realize the mutual check of angular deviation for regular polygonal prism and precise angle dividing table. After each serial measurement, it is not necessary to change the relative position of the two pitch circle devices, so the process of mutual check is simplified and the measuring time is shortened. The mutual check principle and operation steps, the design of experimental device were introduced in detail, and the experimental data of the mutual check for regular polygonal prism and precise angle dividing table were presented. Furthermore, the random errors of the measurement results were analyzed and calculated. At last, by comparing the results of two different experiments, the correctness of this method was verified.
