Abstract


CAPP as process design system platform has been gradually shift to the three-dimensional CAPP application of 3D CAPP system focuses on the automation of the identification process of the three-dimensional model of information design . The main content of this paper is needed for parts manufacturing features of the three-dimensional CAP extract , process design repository design and process design . CAPP systems need to deal with the characteristics of the parts , analysis of the characteristics of technology in the part definition , parts information level information : general information layer , feature layer , the characteristics of the surface layer , design the manufacturing feature extraction based on the characteristics of the surface layer method. Developed by studying part model to reconstruct a secondary development interface provided by software in the CAD software . UG environment to achieve . Process design for the CAPP system resources the state of the environment , the automated process . The design process knowledge , as well as the content of the characteristics of the process section . Studied the relationship between the manufacturing method of establishment of the repository data in the device layer and the various resources . The status of the process design process for the CAPP system , the automation process design , including parts manufacturing feature information processing method , and parameter definition , process definition . Given set of process automation design process . Some key issues in the process of implementation of function : object oriented data structure created to improve the versatility of the data . And process design parameters of the study , developed a method of data transmission and definition . Papers related results have been embedded in the opening goal CAPP application .
