The Presentation method of the mechanical motion scheme must support the whole processof conceptual design. To meet the requirement, a semantic network method is selected to representprocess level, action level, mechanism level and relationships among them. Computer aided motioncycle chart exploration can be realized by the representation and revision of time coordinaton ofmechanism actions and their effect on the design scheme. The uncertain reasoning technology based onsemantic network is applied in the mechanism types selection of the needle driving mechanism ofindustrial sewing mechanism, and the application indicated it is correct, useful and advance.
