| Abstract: | Representation of tolerances is a basis for tolerance analysis and synthesis.Proposes a computer-aided representation method to represent geometric tolerances.Through utilizing the geometric tolerance structure blocks(GTSB),the functions of specific zones of geometric tolerance are established and their allowable variations of degree of freedom in the corresponding directions in three-dimensional space are computed.Representation of geometric tolerance information is implemented by giving the formal definition of all sorts of geometric tolerances through using of graphic theory and by designing the data structure of geometric tolerances.Finally,a case study is given to validate the proposed method. |
