The article describes the system approach to simulation the process of machining hard-to-cut materials using tools with wear-resistant coatings. In addition to increasing the wear resistance of the tool, factors such as thermal state model, load parameters and friction behavior at the tool-chip interface have been analyzed. A comparative analysis of these parameters is described in the article. It has been proven that the greatest wear of the cutting edge does not occur on the top of the tool, but in the area where the chip speed along the rake face of the cutting insert is greatest.

“…It is primarily initiated by the breakdown of protecting surface films under extreme operating conditions, which leads to largescale adhesion, welding of sliding interfaces, and severe wear. Such a problem occurs in many friction pairs like gears, cams and followers, piston ring and cylinder liner pairs, and bearings [1][2][3]. The mechanism of scuffing is quite complex and it is governed by multidisciplinary coupling effects [4,5], including hydrodynamic lubrication, asperity contact, thermal effect, tribochemistry reaction, friction, wear, etc.…”

General reductions in lubricant viscosities and increased loads in many machine components mean that the role of tribofilms has become increasingly important to provide adequate surface protection against scuffing. However, the relationship between the scuffing process and the growth and removal of tribofilm has not been systematically demonstrated. In this study, a multidisciplinary coupling model, which includes hydrodynamic lubrication, asperity contact, thermal effect, tribochemistry reaction, friction, and surface wear, was developed to capture the initiation of surface scuffing. Simulations and experiments for a piston ring and cylinder liner contact were conducted following a step-load sequence under different temperature conditions. The results show that high temperature and extreme load could induce the lubricant film collapse, and then the tribofilm breakdown initiates due to the substantially increased removal process. The failures of both lubricant film and tribofilm progress instantaneously in a coupling way, which finally leads to severe scuffing.
