Outline of Final Research Achievements |
The present study developed a CBN cutting tool focusing on the surface micro topography of the tool for the machining of Inconel 718. Detailed wear behavior of the CBN cutting tool and the relationship between surface microstructures of the cutting tool and wear resistance were investigated. The results indicates that a rake face with micro grooves significantly suppressed the crater wear at low cutting speed, although polished surface rake face reduced the initial crater wear by approximately 40 % compared to the non-polished tool in high speed cutting of Inconel 718.
