Modeling of Tribological Characteristics of Specimens with Wear-Resistant Coating Using Dummy Variables

摘要

In the process of machining, one of the main factors affecting machining tool wear is friction. A decrease in the coefficient of friction between the machining tool and a machined part is a key challenge for researchers. One of the methods to decrease the coefficient of friction and, consequently, to improve the endurance of the tool is the application of wear-resistant coatings. In the current study, modelling of triboprocesses using dummy variables is proposed. Since a peculiarity of modelling of manufacturing processes is a presence of a large number of quality parameters, the influence of all key parameters on the value of the coefficient of friction has been analysed. Also, an adequate model of the dependence of the conditions of the manufacturing process on the coefficient of friction has been developed. The results of the model are important not only for analysis of friction between contact surfaces itself, but also as supplementary and qualitative estimation of different manufacturing processes.
