где E - термо-ЭДС (в мВ) пары "твердосплавный инструмент - обрабатываемый металл", А - постоянная, k - коэффициент, z - показатель степени, определенные из условий предварительной обработки (v = 100 м/мин, s = 0,1 мм/об., t = 1 мм) А = 625, k = 24,7, z = 0,24.The invention relates to metal cutting and can be applied on CNC lathes in the mode of automated determination of the allowable cutting speed corresponding to a given tool life by software, as well as on universal lathes in the manual calculation mode of the allowable cutting speed. The task, the solution of which the claimed invention is directed, is to take into account the variation in the processability of steel billets and cutting conditions when determining the allowable turning speed both in manual mode and in automated determination mode on CNC machines. The technical result, which can be obtained by carrying out the invention, is to provide a more accurate match between the calculated tool life and the actual by measuring the thermo-EMF of the “tool-part” pair directly on the machine under the conditions of a short-term preprocessing. This technical result is achieved by preliminarily processing metal (steel billet) in the speedless cutting zone in the speed range above the build-up zone and measuring the thermo-EMF in the “tool-part” pair and the pre-processing thermo-EMF value and operating parameters of the process a given resistance T in minutes, assigned by the process flow s in mm / rev and depth of cut t in mm, determine the allowable cutting speed according to the following formula:
where E is the thermo-emf (in mV) of the "carbide tool-work metal" pair, A is constant, k is the coefficient, z is the exponent determined from the pre-treatment conditions (v = 100 m / min, s = 0.1 mm / vol., t = 1 mm) A = 625, k = 24.7, z = 0.24.
