摘要：

Aiming at the principle errors or model errors of sphericity error evaluation methods, a sphericity error evaluation method that mets the definition of minimum coverage area was proposed. This accurate method combined geometric search approximation algorithm with geometric structures and definition of sphericity error evaluation based on minimum coverage area method. Simulation data and data from other documents were evaluated. Evaluation results of the proposed method and other methods show that the proposed method may find the accurate sphere's center of the minimum coverage area and obtain the exact solution of sphericity error. © 2020, China Mechanical Engineering Magazine Office.
