Abstract
Use of high-speed diamond grinding is especially important for the processing of superhard materials, since not only productivity increases at significant processing speeds, but also the tool sharpening accuracy. This is due to the high speed impact of grains on a comparable, or the same hardness, processed material and the formation of micro-edges on cutting grains. Article describes ways of improving efficiency of diamond grinding wheels for high-speed regimes using analytical approaches and finite element method. The cost of the tool is still the main limitation for the wider use of diamond grinding, as well as need for a better understanding and monitoring the grinding process. In this direction three main tasks have been solved: modelling the process of super high-speed grinding; determination of rational conditions of diamond grinding, improving the structure of diamond abrasive tool which increases its efficiency. The aim of this study is to develop the basic principles of practical application of the created mathematical models of the high-speed grinding process in a wide range of applied tool materials and processing conditions.
