Francesco Rosa has worked in research and development in various roles for over four years, with people of different nationalities in small and big projects. He is currently a mechanical design engineer in the molded case circuit breakers group, principally covering topics related to cost saving. His technical competencies include 3-D and 2-D technical design, CAD/CAM machining, laser reverse-engineering, additive manufacturing and FEM simulations. Rosa is also skilled in product engineering and project management. Francesco Rosa attended both Politecnico di Milano (mechanical engineering degree) and Bologna University (doctorate). He is currently an assistant professor in the department of mechanical engineering at the Politecnico di Milano. His research interests include gear bending fatigue; methods and tools for geometric modeling of gears; numerical simulations of gear manufacturing processes; and gear meshing.

- Repair of Large, Surface-Degraded Industrial Gears - a New Approach (January/February 2017)
This paper presents a new approach to repair industrial gears by showing a case study where pressure angle modification is also considered, differently from the past repairing procedures that dealt only with the modification of the profile shift coefficient. A computer program has been developed to automatically determine the repair alternatives under two goals: minimize the stock removal or maximize gear tooth strength.
