Austenitic stainless steel is a kind of difficult-to-cut material utilized widely in various industry fields. Hole-making tools are the uppermost obstacle of high performance cutting, so the optimizations of tools are imperative. This paper presents respectively the optimal geometrical characteristics and corresponding coating for high performance cutting austenitic stainless steel. The appreciated cutting performance of optimized tools with optimized cutting parameters has also been evaluated completely through experiments. Optimized special drills with point angle 138° and helix angle 38° was decided and TiCN coating was selected as the best coating. However optimized taps had different geometry structures for tapping through holes and blind holes. The former adopted the spiral pointed tap with inclination angle 15 °. The latter was spiral fluted tap with helix angle 34°. In high-performance cutting austenitic stainless steel, the optimized cutting parameters of special drills are 16 m/min and 0.13 mm/rev. The research results will be of great benefit for the development and application of high efficient and precise drills and taps of high performance cutting austenitic stainless steel. |
