| Abstract: | Based on the research of unwrapped arithmetic of multi-point forming workpiece surface, the unwrapped dimension tolerance resulted from it has been analyzed in theory. Furthermore, as a sphere surface piece for example, the unwrapped dimension tolerance analysis has been proceeded from three point-surface discrete tolerance analysis, quadrilateral mesh shape tolerance analysis and accumulative tolerance analysis resulted from base point. |
