- © 2019 Published by Faculty of Engineering.The present work analyzed the effect of coating chemical composition and thickness layer over the wear behavior of cutting tools intended for the manufacture of steel molds for injection of various materials. A business analytics approach using design of experiments was implemented to optimize wear measurements taking into account the coating variables as well as the manufacturing cost involved. Confirmatory tests carried out on real manufacturing conditions showed a wear reduction of up to 5.7 times while achieving a minimum cost of coating.
