Method of welding groove feature design and weld feature recognition

To solve welding workpiece model, it is important to study welding groove feature design. The design requirements of welding groove were analysed in the numeric CAD/CAPP/ROBOTICS integrated welding. The total scheme was desiged to real-ize the data share between CAD design environment and CAPP/ROBOTICS environment. Firstly a method to model typical welding groove based on groove feature library was given, then a better method to model universal weld groove driving by program developing based on CAD/CAM platform was provided.And the method of welding groove feature and weld feature recognition was put forward. Example proved that it is correct.
