Abstract
Some results of experimental studies on the specific features inherent in the intermittent cutting of quenched steel AISI 52100 with a PcBN tool were presented, and the process of machining with a PcBN tool was analyzed by using the finite element method with consideration for the polycrystalline structure and composition of the tool. To ascertain the effect of the PcBN composite composition on the cutting forces and tool wear, experiments were conducted with cutters of two types of materials with different PcBN content. The obtained experimental results demonstrated the efficiency of the PcBN tool with a low PcBN content to be comparable with the tool characterized by a high PcBN content in the machining of quenched steel AISI 52100 at a cutting speed of 210 m/min under intermittent cutting conditions. The obtained results indicated the prospects and high performability of tools manufactured from PcBN composites of different composition under certain operational conditions.
期刊介绍：
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
