Study of frictional contact during grinding and development of phenomenological model

The processes of the formation of vibroacoustic signals during grinding operations have been considered. Phenomenological models that define the change in vibroacoustic radiation power with an increase in the grinding wheel wear and change in the operating conditions have been proposed. The aim of this paper is to facilitate the development the methods of monitoring friction processes and cutting.     

On the implementation of ultrasonic technology

The results of processing various materials with autoresonance ultrasonic turning are presented. After the ultrasonic processing of metals, nanostructured near-surface layers emerge that are responsible for the macromechanical characteristics of the material. The developed technology allows for the processing of various hard-to-machine materials with the obtainment of a surface of heightened geometrical and mechanical properties and with minimum power inputs and material capacity.
