Experimental aspects regarding the metal cutting tribosystem of the ball nose end mill

Résumé

Ball nose end mills are highly used for 3-5 axis milling operations. The tribosystem of the ball nose end mill demands a detailed study of its internal processes. The current paper concerns a few aspects regarding tool wear during milling. Some direct and indirect effects of tool wear over machined surface quality and productivity are being assessed. The experiments undertaken offer data
regarding tool wear influence over the quality of the machined surface, acoustic emissions and process energy. As a result, conclusions are drawn regarding the cutting strategy used for milling operations with this type of tools and the proper structuring of a tribosystem in its complexity.
