Simulation of Grinding Process of Polycrystalline Superhard Materials

Abstract:

The results of investigation in order to increase the efficiency of using diamond-abrasive and edge tool made of superhard materials (SHM) on the basis of 3D methodology of complex research of the interrelated processes of their manufacturing and operation are presented. Creation of 3D simulation methodology of processes of sintering of abrasive-diamond tools and processes of grinding of edge SHM tools with their application allows us to increase considerably the reliability of obtained results, to reduce the extent of experimental studies for determination of optimum conditions for grinding and to develop new technologies, tools and equipment. The scientific hypothesis about the expediency of using diamond powders with thick metal coatings in diamond-abrasive tools on metal bonds are proposed and proved on the basis of theoretical research. The research results are implemented as a number of grinding techniques with controllable cutting relief of the wheels and devices which realize them. Using the results of the research makes it possible to increase the reliability of the edged tool made of SHM as far back as at the stage of its sharpening.
