Abstract

Abstract: The evaluation of roundness error has an important reference in the quality evaluation of shaft parts. Aiming at the problems of principle error, model error and non-linear solution difficulty in the existing roundness error evaluation algorithm, the area search algorithm is combined with the roundness error minimum inclusive area evaluation method, and the area fan search method is used The error is evaluated. By constructing reasonable simulation data and using the designed evaluation method to calculate the roundness error of the simulation data, the results of the roundness error of different evaluation methods are compared and analyzed. And the actual roundness error evaluation and method verification are carried out through experiments. The results show that this method is simple to operate, stable and reliable, and has higher calculation efficiency, and the evaluation accuracy is significantly improved compared with the least square method, the largest inscribed circle method, and the smallest circumscribed circle method.
