A Multi-objective Approach for Wire-drawing Process

Drawing of wires is a well known process and several manuscripts are recognizable looking at the scientific literature. The main reason why the process is used is related to increasing of the elastic resistance of the materials thanks to the induced yielding. Nevertheless many information are available from a mechanical point of view, today new needs related to process sustainability push toward a process redesign taking into account different criteria. In this paper, a multi-objective approach based on the optimization of a set of objectives is presented. Process force, die wear, material thinning and damage are considered building an optimization problem in which the technologist can decide the role of each criterion in the operative scenario.
