Abstract: The paper presents the methodology for determining the relationship of calculating the torque of cutting in the drilling process, in certain conditions, of a stainless steel used widely. There are presented numerous experimental data and calculations on which it analyses the torque variation of cutting. Research experiments are carried out in laboratory conditions and for representation and calculations it is used the Excel program. The methodology for determining, the experimental data and numerical, and the results of its processing represent contributions of paper to the establishment of the constant values and of the polytropic exponents for the relation calculation. The graphical representations present the variations of the cutting torque with the work parameters, which are factors for a certain recurrent relation, established in the paper.
Key words: cutting, process parameters, calculus methodology, regression relation, results.
