Selection and evaluation of the efficiency of cutting inserts made of various cutting tool materials

Abstract

In Russia, in the last decade, practical steps for rise of machine-building production are taken. The key role belongs to metal working, development of progressive methods of production of details of machines of high constructive and technological complexity. The most effective is the way of intensification due to the expansion of tools' use equipped with artificial superhard materials on the basis of cubic boron nitride modifications. The results of scientific research of scientists and practicians emphasize the benefits of cutting methods of handling with modern tool materials before using the technologies of grinding. The use of machining technologies of structurally difficult details with tools, made from a composite 10, meets the requirements of the developers of the knowledge-intensive competitive equipment, tending to further increase in constructive complexity. Enhancement of machining processing of the details having structural elements of broken surface on the processed planes, with creation of special conditions of cutting by a method of management of the cutting part position, excluding a negative impact of dynamic loads on the tool is an urgent scientific and practical task.
