Tribological Aspects of the Dynamic and Thermal Phenomena Modelling in the Cutting Process

The complex of specific physical phenomena that characterize the cutting process and that influence its development, were not studied as a process as a whole, the processing was done as separate influences for certain specific cases and can be generalized only for small areas. The interpretation of the cutting process as a system in which dynamic and thermal phenomena occur leads to the conclusion that the relationships established until now between the elements that contribute to the cutting process and the effects produced by them give only a global and more qualitative imaging of the process and their use for concrete practical cases can be accepted only by admitting a large margin of error in evaluating the values that characterize the real effects (efforts, wear, temperatures). It was necessary to develop a physical model of the phenomenon in order to perform the researches; in fact, the phenomenon is a conventional image of the real status, representing the basics of mathematical modelling. The model has mathematical equations, functionally describing the physical model, and through it, the real phenomenon. For mathematical model solving, difficult to be analytically solved, there have been used numerical methods to obtain solutions for the differential equations. In essence, the central objective of the this paper is to unify in a single model the multiple phenomena of a dynamic, thermal and tribological nature, in order to assess in advance the intensity with which wear will occur and determine how it can be influenced
