As an example, themachining process planning of up beam of hydraulic press machines is used tointroduce the establishment of process planning match board by means of inferencebased on expert knowledge. The organize model about the process planning matchboard oriented product family is brought forward.5. The multi-decision methods of CAPP system based on analytic hierarchy aregiven.. On the basis of uniform data model, the sub-machining process planning ofpart is auto-created by means of analytic hierarchy, The step decision methods basedon AHP is put forward.6. For the design/manufacture information in the course of product life cycle, thetree structure based on Object-Oriented and static model based UML are founded. Themethod of establishing design/manufacture information management system isbrought forward. The commercial PLM software—SmarTeam is regarded asdevelopment platform, on basis of which, the design/manufacture informationmanagement system is built, and the multi-view mapping technique ofdesign/manufacture information model is studies.7. A computer-aided CAPP platform based on PDM/PLM is founded, and itsstructure, function, work flow is illustrated. Some example of the system areintroduced.
