CADCAM(国外英语资料) The third section introduces the engineering design software At present, many commercial engineering design softwares have been introduced, and some famous engineering design software are briefly introduced. One, CATIA software CATIA (Computer Aided Three-dimensional Interface Application) is CAD / CAE / CAM software system of Dassault aircraft company subsidiary of Dassault SYSTEMES and IBM joint research and development. It is one of thousands of advanced automation design, manufacturing and engineering analysis software, mainly used in mechanical manufacture, engineering design and electronics industry. Main features: according to the process of industrial production, provide the user from concept design, style design, detailed design, engineering analysis, equipment and systems engineering, manufacturing and application software development process oriented design ideas and solutions; with 1 ~ 15 Bezier curve surface and the non uniform rational B spline with calculation method; a strong three-dimensional complex surface processing and programming skills, suitable for aircraft, cars and other complex mechanical product geometry design and NC programming; user interface provides unified data management, data module and application program interface is fully compatible with the. Product function module: three-dimensional design, solid geometry, advanced surface, graphics, image design, construction, CNC milling, CNC turning, conduit installation and pipe forming, robot, architectural design and equipment layout, structure and design of steel structures, principle diagram, kinematics, finite element analysis, interface module, interactive graphical interface, service access management. Two development interfaces: Geometric interface, user interface, graphical interface, industrial standard data conversion, data bidirectional conversion interface and so on. Two, UG II software UG II (UNIGRAPHICS II) is the product of EDS company, it is a set of CAD,
