Abstract: The basic theory of producing cylindricity error graph was studied, and a mathematical model for visualization of cylindricity error was established. The theory of computer graphics and three-dimensional wireframe models were used to realize the display of extracted integral feature, associated integral feature and associated derived feature of the measured cylinders. Axonometric projection transformation was adopted to fulfill the realization of basic geometric shapes. The space hidden method was used to solve the problem of geometrical graph hidden. According to the standard definition of cylindricity error, the mathematical model for cylindricity error graphic display was established. On the basis of theoretical study, software was developed to realize visualization of cylindricity error on the platform of LabWindows/CVI.

Key words: cylindricity error, graph, visualization, mathematical model, computer graphics
