The Study Of Computerized Model Management Technique Of Mechanical Products For PDM System

As the PDM systems are applied widely in our country,some PDM systems which were programed by some domestic software company capture the market rapidly.Managing the computerized models that existed in the mechanical factory effectively is the prime task after using the PDM system for the first time.During the process of computerized models management,some PDM systems cannot form the product structure after importing mechanical computerized models.Otherwise some PDM system also cannot automatically signe or eliminate a name and date after passing or failing a check point in the workflow.Solving the two problems that mentioned above are the key points of effectively managing the computerized models.And the technique of solving these problems is called computerized model management technique of mechanical products.Only if using the techniques of integration of CAD & PDM and secondary programing of CAD and function expansion of PDM system can accomplish the purpose of managing computerized models of mechanical products in a PDM system.This paper is based on a project which was signed between college and company.Using Solid Works and T5-PLM as objects have accomplished the study of integrating between CAD and PDM system.The paper contains several points like the following state:The paper discusses the information extraction methods of model configurations and product structure in detail.Meantime,the paper analyses the methods of processing and storing the information that extracted from the models.A method that could import product structure data and product files to PDM system for one time has been come up with in this paper.These methods that mentioned above have been used in the import & export CAD files area.The paper offers a solution which was based on the XML technique to solve the problem that drawing file cannot be automatically signed or eliminated a name and date after passing or failing a check point in the workflow.This paper simply introduces the concept of secondary programing of Solid Works and studies the methods of reading & writing the secondary programing codes.Using the methods that be suggested in the paper a secondary programing example was being verified.The paper has introduced six plugins which was written according to these methods.These plugins not only solve the problem in the project but also provide a new solution in solving this type of problems.
