Manufacturing IT application characteristics the phased build a model product design, analysis , manufacturing , assembly , information redundancy , data consistency , running in a heterogeneous environment , the use of high cost , low efficiency , and product information is difficult to integrate and inheritance . The nature of the digital model is the carrier of information , complete information model should be the focus of the study of the manufacturing IT . Establish a more advanced model of tectonic theory , research methods and techniques of scientific model construction product information integration and inheritance , an ideal way to build integrated software system to provide all-round support for the product life cycle . Papers to the National Natural Science Foundation focused project engineering and product design theory methods ( 60635020 ) for support , innovatively proposed set of basic body , retrieve the body , control of body and smart body is the same structure of \system and \Classification of product information , information on the characteristics summarized and product information data space model structure building, established a separate unit of geometric topology with the various stages of the product life cycle information contact research information model follow techniques to form a model retrieve the body . Interactive control of the management control of an independent research unit of information storage and read control model information , model and external resources , the distribution mechanism model information and work processes , fully embodies the service function of the model , complete model of the control body . Thesis research the ACIS-HOOPS integrated platform component technology , data structures and application framework , proposed the establishment of a technology roadmap for product information model . Finally , the development of a product information theory -based product information model integrated software system , the system to achieve a wireframe model , surface model and solid model building , model editing , model display have the basic functions of the CAD system , with the properties of the ACIS the mechanism for the creation of a \Thesis work information , mechanical engineering technology research has important theoretical and practical application of significance.
