Abstract: Aiming at the visualization of the evaluation results of cylinder's global sizes, some issues on the local magnification of the extracted profiles of cylinder, the determination of diameters of cylindrical surfaces of global sizes and their axes parameters, the displays of cylindrical surfaces of global sizes and etc. were studied. Based on the cylindrical roundness profiles with local magnification, the evaluation models of diameters and axis parameters of global sizes' cylindrical surfaces were built, and the visualization methods of evaluation results of the cylindrical global sizes were proposed. The calculation model of profiles' coordinates of global sizes' cylindrical surfaces was established on the basis of their diameters and axis parameters. The visualization program of evaluation results was developed by using the above models, and the leastsquares size, minimum circumscribed size, maximum inscribed size and minimax size of one hole were evaluated and their evaluation results were visualized. The results show that the models built in this research are correct and the proposed visualization methods and the developed program are practical and reliable, which can be also used for the evaluation visualization of cylindricity errors.
