In general, pieces manufacturing procedure, through deep drawing, requires operations that must be carried out in several phases that extend the time and the cost of the process. Material determination, by considering shape, dimensions, mechanical characteristics, etc., can provoke an overdose at estimating proportions with the consequent increase of the manufacturing costs. Furthermore, the processes improvement with its simultaneous reduction of costs, provides to a company a higher profit in competitive markets. Thus, this paper introduces an aided system that allows the technological design of multi‐step deep drawing processes, by the optimization of both initial material and process associated costs, and moreover, their application to brass pieces, in particular in CuZn30 alloy (UNS C26000). The aided system considers process technological constraints and pursues a reduction of manufacturing times, by means of the optimization process and fitting. The results show that this system provides, in each stage of the process, a homogenous distribution of the drawing coefficient, thickness reduction, required force and height of the piece, as well as a saving in times.
