Modeling and simulation of burr formation: State-of-the-art and future trends

Modeling and Simulation of Burr Formation is one of the main topics in contemporary basic scientific investigations. Using state-of-the-art numerical methods, the process of burrdevelopment can be investigated within 2D-simulations and more and more also for 3Dapplications. The aim of the numerical analysis (e.g. FE simulation) of burr formation is the minimization of burr. Up to this time, numerically simulations of burr formation - especially for 3D-applications - are very time consuming. So, in contrast to the basic research investigations in to the material removal process during burr formation, methods of predictive modeling are from the practically point of view very welcome in the industrial approach. In view of Virtual Manufacturing, the response time must be dramatically faster than usual in numerically calculations. The most relevant methods applied to burr formation modeling and simulation are accurately reported and discussed in the paper.
