【正文】 of professional courses, 3D modelling and simulation entity processing. First carries on the analysis about the structure of TV box, thinking entity modelling idea, through the modeling module in UG, application of stretching, rotating, characteristic functions such as Boolean operation on entity model. Through to the entity modelling, according to the analysis to determine the processing plan of entity structure, through CATIA processing module, application Settings tool, select blank, characteristic functions such as tool path is generated on the real process. For TV box parts 3D model and entity processing simulation conducted indepth exploration, 3D modelling process was introduced in detail. Through to the shell parts 3D modelling and simulation entity processing, can shorten the product development cycle, reduce production cost, improve product quality and production efficiency, and stimulate new train of thought on the development of manufacturing industry in our country, promote the development of IV manufacturing industry in our country. KEY WORDS: CATIA, Shell parts, 3D modelling, machining simulati V 目錄 摘要 ...............................................................................................................................
