“…However, experimental validations of simulated grinding temperature distribution were not reported in these earlier works. Limited works only been reported so far on the mathematical modeling of grinding temperature distribution for laminated structures of metal and polymer composite materials [28,35]. In [28], Shmidt and Dyakonov applied a two-dimensional formulation of the thermophysical model to simulate the temperature distribution in different metal-polymer composite laminar structures.…”

“…Earlier attempts were also made to decrease grinding temperature of polymer composites either by using electroplated wheel with controlled abrasive cluster [26] or by applying internal coolant through grinding wheel [27]. However, detailed mathematical model of the temperature distribution in the metal-polymer composite layered structure during grinding of its working layer has to be developed to understand the effects of different grinding and workpiece material parameters on grinding temperature to avoid grinding burns [28].…”

“…The thermal physics of grinding uses two approaches to the calculation of the temperature distribution in the grinding area; the scheme of discrete contact in which thermal pulse carriers are considered to be cutting grains of the grinding disk on the contact arc is used in [28]. The scheme of flush contact, when the thermal source is a geometric contact zone of the grinding disk with the workpiece, is described in [36,37].…”

The article covers a mathematical model of a temperature distribution in the three-layer metal composite structures when grinding their working layers. The computer program TEMSS, created on the basis of thermal models, allows calculation of all the characteristics of the temperature distribution in the layers of the metal composite structure, depending on the system structure, material properties of its layers, grinding and machining conditions, and duration. The work establishes the adequacy of the developed mathematical model of the temperature distribution when grinding the metal composite systems. The article covers the analysis of standard metal composite systems with Loctite, Chester molecular, and Devcon polymers on the basis of the temperature distribution model, revealing the influence of lamination on the nature of the temperature distribution. Critical temperatures are defined that determine the occurrence of thermal grinding defects in the metal composite system, including their dependencies on processing conditions and the system structure. Thus, it is found that when grinding a working steel layer of the composite system using the standard grinding conditions recommended in the reference handbooks for steel workpieces, the temperature in the working and polymer-composite layers, as a rule, exceeds the threshold values for these materials.
