The application of the methods of Computer Aided Engineering in sheet metal forming is looking back for several decades. It covers a wide range of activities from the product design through the process planning and process control including sophisticated methods of modelling and simulation. Among the CAE activities, recently the development of Knowledge Based Systems has become an emerging field. Most of the available Knowledge Based Systems are based on simplified plasticity theory and empirical technological rules. Therefore, they are usually not able to give accurate solutions and reliable predictions for complicated forming processes. In the last two decades, significant progress has been also achieved in the numerical modelling of forming processes. In spite of the enormous development of hardware and software facilities, the exclusive use of numerical modelling still seems to be very time-and cost consuming. Therefore the integration of these two fields has great practical importance. In this paper, the challenges and opportunities of the integration of Knowledge Based Systems and Finite Element Modelling in the process planning of multi-step sheet forming processes will be given.
Abstract. Low cost manufacturing in the automotive industry is one of the main targets due to the ever increasing global competition among car manufacturers all over the World. Sheet metal forming is one of the most important key technologies in the automotive industry; therefore the elaboration of new, innovative low cost manufacturing processes is one of the main objectives in sheet metal forming as well. In 2015 with the initiative of the Imperial
