When grinding wheel comes in contact with machined surface thermal coupling occurs between the detail, shavings and cooling lubrication fluid. Depending on machining conditions, heat passes into detail machined from 50 to 83% which results in steel defects. Using results of carried research of thermal fields, thermal processes in grinding operations may be controlled. Through these processes we control quality of upper layer. As the result of carried research the next data are obtained: functional dependence, which allows calculating of rate of heating and cooling for every part of detail to be machined according to machining mode, time and intensity of heating source; dependence of stress calculation on operating time and temperature of heating source while grinding process is carried
