The evaluation of temperature distribution in a local zone under conditions of free orthogonal cutting

The paper is dedicated to evaluation of temperature field parameters in the elements of the technological system when processing by cutting tool based on generalized algorithm of thermo physical analysis and engineering methods for calculating temperatures. This technique is based on the use of the limited set of known solutions of nonstationary and stationary thermal conductivity problems for solid units of schematized forms under various boundary conditions. By combining these solutions and coordinating them through the use of balance equations, the first approximation formula for the temperature field values in technological system elements may be obtained. Despite the fact that the accuracy of the calculations using these dependencies is low, that is a natural consequence of a number of significant simplifications, taken when constructing physical models of technological systems, they allow you to clearly identify varied factors influencing thermal processes in the technological system, set the direction and power of their influence.
