Abstract The disadvantages of the present geometric tolerance theory and the associated standards are analysed systemat ically, and the stat istical tolerance concept is proposed. The characteristics of the statistical tolerance system are clearly ident ified as being advantageous. In the analysis, w e clearly point out that the stat istical tolerance means the tolerance of statist ical parameters, and the stat ist ical tolerance system w ill be the development direction after the geometric tolerance theory. The development of the process for surface roughness evaluat ion is used as an example to illust rate the finding s for the statistical tolerance.
