The competitive market requires well-developed components; to reduce the wastes during the manufacturing process is considered an opportunity to perform it. It is considered that during the development of a component about 70% of the manufacturing costs can be estimated. This article proposes the application of Design for Manufacturing (DFM) in the steps of the Topological Optimization (OT) in order, to standardize and unify components, facilitating directly and indirectly manufacturing process at the same time reducing the wastes. In addition, the OT application commonly results in a component with lower mass, consequently it is possible to achieve a better and organized production system (Lean Manufacturing). For the wastes described in Lean Manufacturing (transport, inventory, motion, waiting, over-Processing, overproduction) it was proposed equations an analysis to measure the impact of the OT in each of the seven wastes. It is observed that the gain generated by the OT is not only related to mass reduction of the component, but also in the manufacturing system.
