Relation between Power and Linear Model of Dynamic Cutting Coefficients

Fundamental importance for the stability analysis results has assumed model of the dynamic cutting coefficients. In most cases it is based on the model of cutting forces in steady state conditions. The models most often used are based on Kienzle power function and linear, proposed by Altintas. The paper presents interdependence of these models and the way of calculation one from another linear from power and power from linear. The in-depth analysis, how the linear model of Altintas and Kienzle power function model can be potentially applied for modelling dynamic cutting characteristics is presented in the paper.
