Abstract
High speed machining of Inconel 718 with SiC whisker reinforced alumina, silicon nitride and TiC added alumina ceramic tools was carried out. All the ceramic tools tested showed the maximal value of the notch wear around the cutting speed of 100 m/min. SiC whisker and silicon nitride ceramic tools showed good performance compared to TiC added alumina ceramic tool in respect of the notch wear under the low cutting speed or low feed rate. However, over the cutting speed of 400 m/min, not only the notch wear but also the flank wear of these tool became large, while TiC added ceramic tools showed the smallest wear compared to other tools. Notch wear of these tools can be suppressed by pouring the cutting fluid at the depth of cut line.
