Abstract
Today’s automotive market is highly competitive. As a result carmakers are being forced to offer newer, better, and cheaper cars in a shorter period of time in order to stay competitive in the global market. One way to achieve this goal is the introduction of platforms where each part is produced in a highly integrated and cost-efficient process. Now, during the design phase, the demands of cost-effective manufacturing must be taken into account. During the design phase, parts — in addition to the optimization of their function — have to be optimized with respect to their manufacturing process. Design, engineering, and production planning of a part are integrated to a high degree and often take place at the same time (concurrent engineering). Starting with the analysis of the joining process, this paper discusses requirements for an automated welding process based on feature technology. In this sense, flange creation and design, manufacturing, and welding requirements for automatic generation of spot weld are described. A process-oriented prototype is described, which has been integrated in CATIA V5, currently used as CAD-CAM system, and which fit the requirements of the designers and process planners.
