This article considers a possibility and an algorithm of the mathematical study of polynomial dependences which are used for describing characteristics of machining. The authors describe advantages of polynomial dependences obtained on the basis of a complete factorial experiment in multidimensional parameters spaces. For illustrative purposes, an analysis of energy consumption during two-stage lathing was carried out on the basis of the obtained polynomial dependence of the tangential cutting force on processing factors. The influence of the specified factors was established a priori on the basis of conducted experimental studies or literary sources. Conditions and results of all the conducted experiments are presented in this paper along with the algorithm for determining the minimal value of energy consumption.
