The rapid development of CAD/CAM technology and the software and hardware level of further improved, provided strong technical support for the manufacturing industry, also for the enterprise product design, manufacturing and production level of ascension brings a qualitative leap, CAD/CAM technology has become the inevitable choice of modern enterprise information, integration and networking.
In modern industrial production, most of the products need to be 3D modeling and simulation entity processing, based on the aircraft system of control chassis parts as an example, the application of CATIA software, combining the theory of professional courses, 3D modeling and simulation entity processing. First carries on the analysis about the structure of the aircraft system of control chassis parts,thinking entity modelling idea, through the modeling module in CATIA, 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 Settings tool, select blank, characteristic functions such as tool path is generated processing simulation conducted in-depth exploration, 3D modelling process was introduced in detail, to the real machining simulation is also carried on the detailed elaboration, and has carried on the simulation validation of VERICUT.
Through to the aircraft system of control chassis 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 manufacturing industry in our country.
Key words: CATIA, 3D, machining simulation, validation of the simulation
