Open publisher page 0 citations

Abstract

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.
