Contributions towards the concept of metal cutting tribosystem

Résumé

The systemic approach of tribological processes involves a global vision and in the same time a vision specific to each type of process. Within a tribosystem a series of tribological phenomena take place, which will grant the system’s outputs (machined surface quality, absorbed energy etc.) with values in direct dependency with the phenomena. Metal cutting tribosystems have a certain tradition in Romania. The definitions given by different authors to the notion of tribosystem are presented in this paper in a very succinct way. The concept of metal cutting tribosystem has at its core the metal cutting coupling which in turn is defined by means of basic couplings. A tribosystemic structure oriented on single- and multi-point contact tools as well as on abrasive ones is being proposed. Taxonomy in this direction is much needed.
