Abstract
This paper discusses a robust, computational geometry based technique to establish the roundness error of a measured workpiece in an industr ial environment. For evaluating the roundness error, a mathematical fo rmalization has been developed. The properties of a convex hull and th e nearest and farthest Voronoi diagrams have been exploited to establi sh the ideal geometric features required in the assessment problem as per the standards. The methodology has been implemented and the exampl es have been presented to validate the computational effectiveness of the approach. The proposed method can be easily adopted and installed in the Coordinate Measuring Machines (CMMs) and other computer aided m easuring instruments for ready industrial applications.
