Abstract
This article is focused on the features of the structure of ultra-fine grained metals and the influence of the machining on its changes. The search for optimal parameters was carried out for machining of pure copper, obtained by the method of several plastic deformations. The objective function, which includes a new criterion of optimization, was proposed. Limitations of the function for turning ultra-fine grained copper were obtained from experimental data. As a criterion of optimality, a general combining criterion is proposed, which is based on the linear convolution, two particular criteria the productivity and size of the grain size of nano- and ultra-fine grained metals, each with its own weight coefficients. The optimization problem was solved by the penalty function method in the MATLAB software environment using the method of unconditional mini-mization of several variables. Optimal decisions on the selection of the cutting speed and feed during the rotation of ultra-fine grained copper with different initial grain sizes are obtained.
