Abstract

This essay presents a study on the exchange of tools in suppliers of machining service from São Paulo State. We pursued to identify if companies apply the principles of Quick-Change Tools – TRF - and discern the benefits provided by this application. After a survey conducted with representatives of 24,1% of the companies machining industry throughout the State, this study observes the individual and collective contributions of the companies concerning the exchange of industry tools. The analyses were conducted by the ROC algorithm (Rank Order Clustering) aimed at the formation of groups of companies in order to identify those whom know the benefits from the TRF and apply, those who claim knowing the benefits but don´t apply TRF effectively, and those who claim to ignore the benefits and end up not applying TRF effectively. The results revealed that the vast majority of companies know the methodology of SMED and realize its benefits; however, analysis of concerns relating to the changeover activities and their respective times also showed that more than half of companies surveyed do not effectively apply this methodology.
