Abstract: A system and method for automatically estimating the optimized cost of a part during the course of design of the part on a computer-aided design (CAD) system by a designer. The method includes extracting parametric features of a current design from the CAD system. Manufacturing cost drivers are identified on the basis of the parametric features. The manufacturing cost drivers are translated into costs using process models. The costs are simultaneously optimized with respect to a plurality of operations within specified machine constraints using an algorithm with dynamically linked structures to obtain estimates of optimized costs and cost reasoning. An estimate of optimized costs and cost reasoning is fed back to the designer as an output display on an output device.
