Investigation of thermophysical characteristics of profile deep grinding based on finite element modeling

One of the promising methods of processing hard alloy products is profile deep grinding with diamond wheels. The object of the study is the qualitative characteristics of the surface layer of T15K6 and VK8 hard alloy samples after profiled deep diamond grinding. The subject of the study is contact temperatures and temperature stresses in the treatment area. The purpose of the work is to study temperatures and temperature stresses in the processing zone during profile deep diamond grinding of hard alloys to predict the defects and quality of the surface layer. The simulation was performed for the radius profile of deep diamond grinding of a hard alloy using the SolidWorks Simulation 2015 software. A computer model of the temperature field has been developed and graphical dependences of the distribution of temperatures and temperature stresses along the length of the contact arc, along the profile of the sample and along the depth of the product have been obtained. Based on the simulation results, conclusions are drawn about the zoning of the maximum contact temperature and temperature gradient. It has been theoretically proven that the use of COOLANT makes it possible to reduce temperatures in the treatment area by up to 30–40 %. When grinding without coolant, the temperature stresses exceed the ultimate strength of the material.
