Abstract
Originally, the machining centers emerge as a true milestone in the history of mechanical metal, reducing a work that, manually, would take hours to months, running the risk of, at the end of the process, not having the facet of the cutting according to specified patterns and thus, not fitting the purpose it was designed and molded for. In this sense, the new concept of the use of machining techniques is more precise, with minimal chances of errors, but as in the craft production, the errors exist and can be even more aggravating leading to immeasurable losses of production. As with any specific machine, machining centers require parameters and special maintenance, otherwise their productive quality tends to decline causing expressive reduction of the production potential, eminent production of reject as well as waste of raw material. This way, the article will present a proposal for improvement, in the light of a certain machining center which has been presenting production decline over the last six months. The studies initially concentrate efforts to identify the root cause for such decline applying the DMAIC methodology, and will later, present a structured and efficient project.
