| ABSTRACT |
|
Nowadays, the increasing global competition forces manufacturing enterprises to apply new technologies such as laser welding to manufacturing of their products. In case of automotive industries, they interest in assembly system{{br}}for BIW (Body in White) carrying out laser welding. In this paper, the method of implementation for digital laser welding assembly system is proposed. Based on the requirements of assembly tasks obtained through product analysis, process modeling is executed by using the IDEF0 and UML model. For digital assembly system, the selected components are{{br}}modeled by using 3D CAD tools. According to the system configuration strategy, lots of the alternative solutions for the{{br}}assembly system of welding side panels are generated. Finally, the optimal laser welding system is chosen by the{{br}}evaluation of the alternative solutions with TOPSIS (Technique for Order Preference by Similarity to Ideal Solution){{br}}method. |
