概要

• 論文の詳細を見る

• Approximate Correction Method (ACM) and Exact Correction Method (ECM) are proposed to remove the form distortion caused by the eccentricity of a measured part when estimating the roundness error on the basis of Minimum Zone concept. Numerical tests and measurements are performed using BFGS formula for optimization. As a result, it is found that ACM is a practical method from the viewpoint of both computation time and accuracy, and that ECM is an effective one for measuring roundness error with extremely high accuracy for any eccentricity although a little more time is taken.
