Research Of Sheet Metal Stamping CAPP System

With the rapid development of China’s aerospace, telecommunications, automotive,appliance and other industries, market demand for sheet metal parts is growing,Three-dimensional software applications in sheet metal design process greatly reduces thesheet metal product design cycle, However, the existing three-dimensional software for sheetmetal module can only be achieved expand and shape the rules simple piece of sheet metalparts to start nesting, For complex sheet metal parts expand and expand irregular pieces ofsheet metal nesting, process planning and the subsequent lack of effective solutions,Therefore, to develop a design that contains the sheet metal to craft making computer-aidedprocess planning system has great significance.Papers with Visual Studio2008and Pro/Engineer software secondary development Pro/TOOLKIT for the development of tools to Pro/Engineer Wildfire5.0is a graphical softwaresupport platform, On Pro/E secondary development, sheet metal parts can be parameterizedexhibition launched not show sheetmetal approximate expansion, irregular pieces of sheetmetal to start nesting, and integrated Tianhe CAPP, realize process planning sheet metal parts.The main contents are as follows:Firstly, through the analysis of domestic and international sheet metal stamping researchstatus and development trend of computer-aided design and manufacturing, the paperdescribes the study of meaning and purpose.Secondly, detailed sheet metal unfold, the theoretical basis of nesting and processplanning CAPP system development.Third, the development process sheet metal stamping CAPP system specific description.Including the creation, acquisition parameters interactive window and modify, control anddrawing generation view window, the corresponding Pro/E secondary development ofwriting and debugging programs, and Tianhe CAPP integration process and so on.Fourth, with examples demonstrate, detailing the steps and precautions system. Finally, we summarize the overall function and lack of sheet metal stamping CAPPsystem, in order to further specify the direction of future research.
