Sphericity Evaluation Based on Minimum Circumscribed Sphere Method
The search of sphericity evaluation is a timeconsuming work．The minimum circumscribed sphere (MCS) is suitable for the sphere with the maximum material condition． An algorithm of sphericity evaluation based on the MCS is introduced．The MCS of a measured data point set is determined by a small number of critical data points according to geometric criteria．The vertices of the convex hull are the candidates of these critical data points．Two theorems are developed to solve the sphericity evaluation problems．The validated results show that the proposed strategy offers an effective way to identify the criticaI data points at the early stare of computation and gives an efficient approach to solve the sphericity problems．
