Investigation of Cutting Processes and Surface of Plastic Deformation in Environment of LCTE with Nanosize Antifriction Particles

In the article, the authors examine the possibility of using the effect of selective transfer (wearless friction) in technological processes and operations of handling, providing for a significant reduction in cutting forces and deformation within the machining of parts. This, in its turn, reduces the energy intensity of technological operations and significantly reduces the cost of manufacturing machine-building products. In addition, the wearout of the tool and its consumption are reduced for manufacturing of a given batch of parts in the production cycle. An effective method of smoothing out details with replaceable polyhedral plates is proposed with a change in the way the tool is installed, and the authors designed a special device to change the position of the tool relative to the workpiece in three coordinate planes. The regularities of the formation of microgeometry during cutting and smoothing of parts with replaceable polyhedral plates were experimentally investigated. The optimum concentrations of the Valen additive with nano-sized antifriction particles were determined to obtain the minimum height of the microgeometry on the treated surface of the part.
