Experimental and numerical analysis of the deep drawing process using optical measuring system

In this paper optimization of the deep drawing process with using a modern photogrammetric measurement system is discussed. The results obtained from optical measuring are compared with the results of a numerical simulation. The numerical simulation of this process was performed using two commercial FEM codes, which use different time integration schemes. Various results are illustrated in the details, compared and discussed. Optimization of the deep drawing process can reduce the amount of product defects, production cost and can improve the quality of products.
