Evaluation of Local Deformation Values of Stamping in Comparison with Optical Forming Analysis System

Abstract:

There is a persisting trend in automotive industry to increase quality of parts along with productivity while decreasing the cost. All of those three goals are possible to achieve with help of the optical forming analysis system. However, optical forming analysis system is not always capable of calculating an exact result and there are cases when there is no such system available. Therefore there is a need for verification of results provided by the optical forming analysis system. Finding another method for cases where there is no such system available is also desirable. The dependence between grain size and strain is examined in this paper. The grain size was selected as an evaluating parameter due to its connection to the strain and because it is relatively easily measured. Measuring of the grain size was proved to be an alternative method to optical forming analyses in order to determine the strain of press formed parts.
