Paper Abstract

This paper explored the restraint and recognition for offset components and the estimation of sphericity error. Two methods for processing offset components are put forward. The "meridian method" is applied to measure sphere comtour ; The "sequence elimination offset method" is applied to recognize and eliminates horizontal offset component. The restraint methods for other offset componenets are also discussed in this paper. Besides, according to the conception of least zone, the paper also puts forward "optimum method" to evaluate the position of sphere center and sphere error.
