圆度误差评定方法的研究

Research on Methods for Roundness Error Evaluation

圆度误差评定是否准确,将直接影响到机械产品的性能和寿命。介绍了4个简单而有效的算法来评定圆度误差,即最小外接圆、最大内接圆、最小区域法和最小二乘圆法。利用MATLAB对上述算法进行了验证,说明文中算法有效。

Whether roundness error can be evaluated accurately and efficiently or not will directly influence the mechanical product performance and life.For this reason,this paper introduces simple and efficient algorithms to evaluate the roundness error from the measured points using four internationally defined methods： Least Squares Circle（LSC）,Minimum Circumscribed Circle（MCC）,Maximum Inscribed Circle（MIC） and Minimum Zone Circles（MZC）.A software has been developed using MATLAB to apply these algorithms on the test data.
