| Research Abstract |
The tool lives in turning of BN free-machining steel were obvious longer than those of standard steel. In particular, the tool life of TiC added alumina ceramic tool reached about 10 hours in the case that the tool life criteria was set at VB=0.3mm. This tool life was twice as long as that of coated carbide tool. In intermittent cutting, when depth of cut was set at relatively small, TiC added alumina ceramic tool was able to be used.
