Current Advances in the Development of Abrasive Tools and Investigation of Diamond Abrasive Machining Processes (Materials Science Approach). Review

Resumo

The paper reviews the latest advances in the development of abrasive tools and investigation of diamond abrasive machining processes. The review demonstrates the necessity of taking into account the interaction between abrasive and workpiece materials as well as the influence of elements of a workpiece material on wear of abrasive grains; also, it shows the importance of sorting diamond grains by shape, especially within a wide range of their strength. Special features of application of CVD diamonds and the methods for changing the diamond–bond interface zone in order to improve grain retention are discussed.
