A study of the cutting temperature during turning of hardened steels used for the manufacture of marine parts
The article presents a solution to the problem of studying the cutting temperature corresponding to the optimal modes of solid turning of structural alloy hardened steel 15KH (HRC 55) used for the manufacture of machine parts included in the design of marine vessels. The radial component of the cutting force and the cutting temperature when processing hardened steel with cutting ceramics are used as optimization parameters. The influence of two factors of cutting speed and feed rate on the turnover was investigated. The method of the experiment and its results are presented. The empirical dependences of the radial component of the cutting force and the cutting temperature on the cutting speed are presented on the basis of the experimental dependences obtained with the help of the program "Microsoft Office Excel" on the dependence of the cutting force and the cutting temperature on the cutting speed and feed per revolution. The nature of the influence of each factor on the optimization parameter is determined. As a result, the optimal values of the factors corresponding to the minimum value of the radial component of the force and the corresponding cutting temperature were determined.
