ANDERSSON † ‡* Today, shortened lead-times in the automotive industry have raised requirements on rapid information exchange. The increased use and access to the Internet have created possibilities to transfer information to people independent of location. This development, together with the increased speed in the portable computer technology, has opened possibilities for bringing results from sheet-metal-forming simulations directly to the customer. Previously, the results were presented with pictures; now it is possible to use animations. The only requirement is to have access to a post-processor or a viewer that is powerful enough to handle the results. The advantage with animated results is the improved possibilities to follow the sheet-metal-forming process.In this project, the methodology for reporting results from sheet-metal-forming simulations at Volvo Cars Body Components is studied. A potential for improvement would be possible if the reporting procedure is changed from paper copies to a database structure. In the database the results should be stored as files with animated results that the user is able to rotate and zoom. This methodology will contribute to faster and more accurate decisions because it will be based on current information and the user could easily analyse the results without access to special programs. IntroductionSheet-metal-forming simulations have become more common in the automotive industry during the past decade and are efficient tools for many applications. The most significant advantages compared with try-out methods are the time and cost reductions. The use of sheet-metal-forming simulations in the automotive industry has been described by Makinouchi (1996) and Makinouchi et al. (1998).The use of sheet-metal-forming simulations enables the possibility to visualize the forming process. With the simulation technique, it is possible to animate the process and thereby analyse it during the punch stroke. If the same analysis is performed in a real tool, the punch stroke would be stopped at different heights and both material and time would be waste...

Towards the Digital Model of Tool Lifecycle Management in Sheet Metal Forming

“…Successful tool design and manufacturing techniques and emphasizes the importance of a knowledge-based approach that combines computer-aided techniques with human experience in predicting tool life [21,22]. There is intense information exchange between the people working with sheet metal forming simulation, Finite Element (FE) specialists, and the people working with the die design (process engineer) [23,24]. AI techniques developed and applied in stamping die design are: expert system (ES), knowledge-based system (KBS), neural network (NN), fuzzy logic (FL), agent-based system (ABS), rule-based system ( RBS), analytical hierarchy process (AHP), object oriented techniques (OOT), and case-based reasoning (CBR) [25].…”

Parametric study of friction stir welding using elastic return

“…It is for this reason that these alloys are used in several industrial sectors. Folding is the process of forming by cold deforming, which consists of deforming a flat sheet by changing abruptly the angle [9][10]. Therefore, there is inevitably an elastic deformation that accompanies it, as the elasticity value of the material can be exceeded in the folding processes, but not the limits of elastic force.…”

Integrated Process Simulation and Die-Design in Sheet Metal Forming

“…Obviously, there are tremendous efforts to successfully link CAD and FEM systems, however, still there are a lot to do in this field [17]. This solution requires a fully integrated approach of computer aided product design, process planning and die design, as well as the finite element simulation of the forming processes.…”
