Resumen
Research on the geometric tolerance control method of precision machinery based on imagemodeling and new saturation function. First, image-based modeling techniques provide a newway to control the saturation function with a dynamic boundary layer froma computer graphics perspective. Then, it proposes a method to represent the dimensional and geometrictolerances of precision machines using changes in the position of control points of geometricelements. Finally, the main content of the tolerance analysis method based on Monte Carlosimulation is proposed, that is, the position of the azimuth control point of all geometricelements on the measurement chain is determined experimentally by using a randomnumber generator. Experiments have shown that the nominal distance between the control points isthe nominal size of the geometric elements, and by comparing the variation of the control points with the nominal distance of the control points, it is easy to determine the relationshipbetween tolerance and tolerance. accuracy.
