CAD/CAM System for Arc Welding Robots in Vehicle

To improve the level of automation welding of vehicle and to replace the previous teach and play way of robot,a CAD-based off-line programming system of arc welding robots in vehicle(VWROBCAM) is developed by OpenGL and Visual C++ programming toolkit based on OOP(Orient object program).A 3-D feature-based automatic modeling for vehicle is built.The characteristic information of weld is recognised by the interface of COM.The vehicle-based 3-D CAD graphics is integrated to CAM simulation environment of robot station by OLE(Object linked embedmen).The system is realised and tested by graphics simulation of executing vehicle-based welding process.
