Mathematical Model on the Visualization of coaxiality Error

Abstract

The fundamental theory of generating coaxiality error graph is studied. A mathematical model for visualization of coaxiality error is established in accordance with the definition of coaxiality error in national standard. The theory of three-dimensional wireframe models on computer graphics is applied to realize the display of extracted derived feature and associated derived feature on the measured multi-diameter axle. Axonometric projection transformation is used to attain the realization of basic geometric shapes. The spacial hidden method is adopted to solve the problem of geometrical graph hidden. According to the above theoretical research, the corresponding software is developed on the LabWindows/CVI software platform to realize the visualization of coaxiality error.
