The computing system for definition of conditions of cutting

The purpose of the present paper is perfecting of physical model of cutting process for an equilibration of amount of unknown parameters and amount of the equations organizing its mathematical model. The modern level of metal cutting science does not merge achievements of thermodynamics and the statistical physics at mathematical modelling. This require to change physical model. It is necessary to use such a complex factor which merges statistics and thermodynamics laws. Work is such a complex parameter and the proposed mathematical model uses this parameter as a criteria of cutting edge workability. The advantage of new calculation concept is that the flexible mathematical approach is offered convenient for the automated calculations. It is especially important, the mathematical model allows to calculate characteristics of the cutting process at turning without any joint tests of the tool and workpiece materials. The created mathematical model is informative. It allows not only representing necessary knowledge from the metal cutting theory, but it allows joining the new knowledge. The program for calculation is compact. It does not demand extensive databases. The workmaterial database includes the parameters of stress-strain curve gained at the standard tensile tests, as well as parameters of expression for the cutting temperature calculation.
