Abstract:
With the increasing complexity of manufacturing processes and the interrelations between the different phases, the possibility of a phase being affected by a preselected desing variable is very high. In that case, the influence of a desing variable not only on the part performance of but also on the feasibility and efficiency of its manufacturing should be considered. Concurrent engineering approaches should then be adopted to take the control of such complicated relations among the subprocesses. In this thesis a concurrent design optimization methodology was proposed to minimize the cost of a cold forged manufacturing process using the design parameters as optimization variables. An objective function was defined combining material cost, manufacturing cost, and post manufacturing cost of the product. The part to be optimized was a simply supported I-beam under centric load. Nelder-mead was selected as the search algorithm and analysis was carried out using ansys, some geometric parameters were chosen as optimization variable. Results show considerable improvement in the cost
