Abstract:

In this paper, the problem of minimizing the number of drawing stages and heat treatments needed for the multi-stage deep drawing of cylindrical shells is addressed. A conventional rule-based computer-aided process planning (CAPP) is utilized within a dynamic programming approach to generate a set of alternative optimal process plans. A finite element analysis is carried out to guide the selection of the appropriate process parameters and to verify the applicability of the selected process plans. A case study is presented to demonstrate the developed approach, and the results suggest that the combination of rulebased CAPP, dynamic programming and finite element validation could be a valuable, reliable and quick computer aided process planning approach to this complicated problem.
