Tools, powders, pastes: the influence of thermomechanical phenomena on the cutting process stability and wear of cutting tools

摘要

To improve wear resistance of a tip of a truing roller, an angle diamond truing roller is proposed which has a specially designed tip containing coarse diamond grits on its cylindrical rib. The roller performance has been studied in truing worm gear-grinding wheels. It is demonstrated that this roller's life is twice as long as that of conventional rollers. The brittle fracture of a diamond grit under dynamic conditions has been studied theoretically and experimentally.
